Carbon steel and stainless steel sound similar, but they are actually very different cookware materials. Both make useful cookware, but they have unique properties that cooks should understand before deciding which to buy (and for what).
Here we will talk about each metal's strengths and weaknesses, explain the tasks each is good at, and share some of our favorites.
Carbon Steel Vs. Stainless Steel at a Glance
Here are the basic features of both metals at a glance. Don't worry about where we get technical because you don't have to remember the numbers or the terms, just what those numbers tell you, which is:
1) Stainless steel heats extremely slowly and unevenly, which is why it's clad to aluminum and/or copper in cookware, which makes it fast and even heating.
2) Carbon steel heats better than stainless steel, but is still slow and uneven compared to aluminum and copper. However, once heated carbon steel hangs onto heat better than most clad stainless cookware.
These are important features to think about so you can pick pans based on what each metal is best at. The other important features to consider are also listed in the table.
Feature | Carbon Steel | Stainless Steel |
---|---|---|
Metal Content | iron and carbon (0.5-2% carbon) | Steel alloy with at least 10.5% chromium and less than 1.2% carbon. Can contain 10, 8, or 0% nickel. |
Cookware Construction | 100% carbon steel | Stainless steel clad with aluminum and/or copper. Can vary from 3 layers up to 7 layers (more not always better) |
Thermal Conductivity* (speed/evenness of heating) | 51 W/m-K | 16 W/m-K (steel) 237 W/m-K (aluminum) 401 W/m-K (copper) |
Density | approximately 7.85 g/cm3 (varies slightly by carbon percentage) | approximately 7.85 g/cm3 (varies by alloy content) |
Specific Heat (Heat Capacity)** | 500 J/kg-K | 500 J/kg-K |
Weight | Heavier than stainless steel*** | Lighter than carbon steel*** |
Heat Limits | Usually up to 800F or more | Usually up to 600F |
Durability | Extremely durable; will last forever | Extremely durable; will last forever |
Stability | Must be seasoned to avoid rusting and reacting with acidic foods | Extremely stable; won't rust, corrode, or react with foods |
Ease of Care | Must be seasoned but virtually nonstick when it is; must be hand washed and dried | Easy to care for but foods can stick to it; most stainless can go in the dishwasher |
Budget | $-$$ | $$-$$$$ |
Uses/Versatility | Best for skillets, omelet pans, crepe pans, woks, and enameled cookware | Good for all types of cookware |
* Thermal conductivity measures how fast a material absorbs and transmits heat. It is measured in watts per meter Kelvin (w/M-K). The higher the w/M-K number, the better the thermal conductivity.
** Specific heat is the amount of energy needed to raise or lower the temperature of a material. When multiplied by a material's density, it measures heat capacity, or a material's ability to hang onto heat. Specific heat is measured in Joule per kilogram per Kelvin (J/kg-K). The higher the number and the thicker the material, the longer the material will stay hot.
***Though the two metals have nearly the same density, stainless pans are typically clad to aluminum (density: 2.7 g/cm3). This makes a clad stainless pan lighter than a carbon steel pan of the same size. Copper is more dense than stainless, but is found in thinner layers in clad cookware, so is also usually lighter than carbon steel.

Carbon Steel Pans
First, let's look at carbon steel, which is an older and more traditional cookware material. It's been around for at least a few centuries and is loved by French and Chinese cooks especially for its durability, low cost, and semi-nonstick properties.
What Is Carbon Steel?
Carbon steel is an alloy made of iron and carbon. It can range from 0.5% carbon up to 2% carbon. Carbon steel used in cookware is typically 99% iron, 1% carbon. Carbon steel with a carbon content of 0.6-1% is called "high carbon steel." It is a very strong material used in many industrial applications as well as in cookware and high-end kitchen knives.
Carbon Steel vs Cast Iron
Yes, we're comparing carbon steel to stainless in this article, but we also compare to cast iron because it's what carbon steel is closest to in composition, durability, stability, price, and heating performance.
Cast iron contains 97-98% iron and 2-3% carbon; remember that carbon steel pans contain about 1% carbon. The higher carbon content in cast iron makes it more brittle than carbon steel, which is why cast iron is always thicker and heavier: thinner versions of it would be too brittle to make durable cookware.
It depends on the gauge (i.e., thickness), but typically a carbon steel pan weighs about half as much as a cast iron pan of the same size. Fans of carbon steel will claim that it sears and browns every bit as well as cast iron, but the physics of the materials make this wishful thinking: the thinner walls and lighter mass of carbon steel can't retain heat as well as the thicker, heavier cast iron.
Carbon steel does a good job searing, but cast iron will always be better.
What Are Blue and Black Carbon Steel?
Blue and black carbon steel are variants of carbon steel seen often in cookware. "Blue" and "black" refer to carbon steel that has been heat treated to harden the surface, which helps to prevent rust and corrosion (sort of like anodized aluminum). The treatment darkens the steel so instead of being silver, it looks blue or black even when new.
Blacking and bluing carbon steel are technically different processes, but the end result is the same as far as cookware goes. That is, the treatments help prevent rust and do not affect heating properties.
Also, as you add layers of seasoning to your pan, the colors will darken to the same deep brown color whether your original pan was blackened, blued, or untreated carbon steel.
Blue and black carbon steel will resist rust, but they are not rust-proof. You still have to season them, hand wash, and dry thoroughly after use to prevent rust.
Are blue or black carbon steel better options than untreated carbon steel? They look great, but as we said, the performance is not affected, and seasoning makes it kind of a non-issue.
Is Carbon Steel Nonstick?
Some companies today are marketing their carbon steel pans as nonstick, but the truth is a little more complicated than this.
Well-seasoned carbon steel comes close to true nonstick, but it will never be as slippery a new PTFE pan. Some people swear they are, as do the makers who are selling "nonstick" carbon steel pans, but they can't compare to PTFE (Teflon), which is the most slippery substance known to man.
Even so, you can get excellent results from carbon steel and cast iron both. For food to not stick to carbon steel (or cast iron), pans need to be seasoned--at least a few times before first use, even if bought pre-seasoned.
For best results, you also need to use enough cooking oil to coat the pan well. This doesn't mean you need to use a ton of oil. Just enough to thinly coat the entire pan. (When you use enough cooking oil, all pans are nonstick.)
Even though carbon steel isn't as nonstick as Teflon, there are good reasons why you should use it instead of Teflon: no potentially toxic chemicals, the ability to use high heat and metal utensils, and a smaller carbon footprint on the planet are the biggest reasons we can think of.
Your carbon steel pan will last for decades, while you have to replace nonstick pans every few years. This not only gets expensive, it is a landfill issue, too, since most recycling centers do not take coated cookware.
If you learn how to use a carbon steel pan, you won't miss your nonstick. Seasoning is easy to do and rarely necessary once the pan has built up several layers of it.

France and China: The Original Users of Carbon Steel
Use of carbon steel cookware is growing in the US for its many excellent features (and perhaps because of recent marketing campaigns proclaiming it a nonstick alternative to Teflon). But French and Chinese chefs have been using carbon steel for a couple of centuries.
The French have long used carbon steel for their omelet and crepe pans. They are cheap, durable, and nonstick (enough), with none of the issues of PTFE nonstick (such as toxins, heat restrictions, no metal utensils, and mediocre browning). Most importantly, they consistently turn out excellent results.
The Chinese also love carbon steel, but for different reasons. Carbon steel is the traditional material used for woks, and we believe it is the best type of wok you can buy. Wok cooking is done at extremely high temperatures (in fact, you can buy special wok burners if you're really into stir-frying because most regular cooktops don't get hot enough to achieve the results seen in Chinese restaurant kitchens).
Carbon steel can withstand high temperatures and is considerably lighter than cast iron--an important consideration if you want to toss the wok like a professional chef does (the standard wok size is 14 inches, so even carbon steel ones are heavy).
Add in that it is inexpensive, will last forever, and develops a near-nonstick, easy-to-clean cooking surface, and you can see that carbon steel makes an excellent wok.
Why Don't Carbon Steel Pans Come in Sets?
We scoured the Internet for an answer to this question and couldn't find anything definitive. So, we will just share our thoughts, knowing they may not be 100% accurate.
Weight: Carbon steel is lighter than cast iron, but it's still heavy. Most people prefer their saucepans and stockpots to be lighter than what carbon steel can offer. The one exception is the Dutch oven, which is simply superb in enameled cast iron and worth the extra weight (click the link to find out why).
The Seasoning issue: Liquids, even water, can strip the seasoning you've worked so hard to build up on your carbon steel and cast iron pans. Since sauce pans and stock pots are used primarily for liquids, you rarely see them in bare (that is, un-enameled) carbon steel or cast iron.
Enameled carbon steel is becoming more popular, as evidenced by All-Clad's Fusiontec cookware, a full line of enameled carbon steel cookware. One source, an ex-employee of All-Clad, told us this is All-Clad's foray into "colored" cookware, which has gained popularity recently. Enameled carbon steel doesn't need seasoning, and can be made in a huge array of colors.
Carbon steel pots can be thin enough to not be overly heavy, but you have to wonder how well they'll perform. Remember that carbon steel's best property is its heat retention, and the thinner it is, the worse it will retain heat.
For now, cast iron reigns in the enameled cookware category, but this may change as carbon steel--and colored cookware--both gain popularity in the US. People may be willing to trade in slightly worse heat retention for lighter cookware, especially if it's available in many beautiful colors.
Are Expensive Carbon Steel Pans Better Quality?
Boutique brands of carbon steel and cast iron have become quite popular in the past few years, with several artisan makers popping up all over the US.
These pans are high quality, and some are also very beautiful (like the blue carbon steel pan from the Northwest Skillet Company shown above).
You may get some features you won't find in lower-priced carbon steel, such as different pan shapes and fancier handles. But as far as performance goes, expensive carbon steel is going to be about the same.
You can get better performance from clad stainless steel and copper cookware as you go up in price, because high-priced brands tend to have thicker layers of aluminum and/or copper. But all carbon steel heats pretty much the same: a thicker gauge will provide better heat retention, while a thinner gauge will be lighter and more responsive. But paying boutique prices for carbon steel won't get you a higher grade of it, because there really is no such thing.
High-end carbon steel cookware brands are extremely durable and will probably last forever, but so will their cheaper counterparts. If you fall in love with a fancy brand and can afford it, there's no reason not to buy it--but there's also no practical or scientific reason to go with a higher-end brand.
Just know that the performance, durability, and longevity of an expensive pan is going to be about the same as a less expensive one.

Joyce Chen 14-inch Wok, 4 Piece Set (About $35)
Whatever you do, please do not buy a nonstick wok. Woks are designed to be used on high heat, and high heat is the public enemy number one of nonstick coatings. Carbon steel woks are cheap, designed for high heat, and will last forever. Our Joyce Chen pick comes with a lid, bamboo spatula, and recipe booklet (though you rarely need a lid for wok cooking, so you may prefer one without: here's a flat-bottomed wok with no lid for about the same price).
Woks are different than skillets or egg/crepe pans in that you want them to be thin. Heat retention is less important in wok cooking because it's done quickly, and the thin carbon steel will heat faster and make the large wok easier to handle (standard wok size is 14" across the top, which is a big pan).
If you have a wok burner and want a round-bottomed wok, we like this one best and this one for a more affordable option.
Don't buy a round-bottomed wok for use on a regular cooktop.

Stainless Steel Pans
Clad stainless steel is one of the most popular types of cookware on the market. It is also one of the most expensive types, with some brands costing as much as high-end copper cookware. Yet many cooks are willing to pay more because cooking on stainless steel is worth it to them.
Stainless steel is durable, stable, and won't rust. So even though the initial cost of good stainless cookware is more than other types of cookware, the cost-per-year-of-use is low because it will last for several decades.
Most stainless cookware also has a lifetime warranty, so if you have any issues, manufacturers will replace a piece free of charge.
What Is Stainless Steel?
According to Wikipedia, stainless steel is an iron alloy that contains a minimum of 10.5% chromium and less than 1.2% carbon. Chromium prevents rusting and corrosion by forming a thin layer of oxidation on the metal's surface; this is what makes it "stainless."
There are hundreds of types of stainless steel that can contain nickel, aluminum, titanium, copper, molybdenum, manganese, selenium, silicon, and more, depending on the application it's used for.
Stainless steel used in cookware usually contains chromium and nickel. These are corrosion preventatives and create some of the highest grades of stainless steel. They are sometimes called "surgical" stainless steel for their use in the medical industry.
The numbers 18/0, 18/8, or 18/10 refer to the percentages of chromium and nickel in the steel. 18/8 is 18% chromium and 8% nickel, 18/10 is 18% chromium and 10% nickel.
18/0 is 18% chromium and 0% nickel; nickel makes steel non-magnetic, so 18/0 is typically used on cookware exteriors to make it compatible with induction cooktops (which require magnetic cookware).
You may see 18/0 steel called "magnetic stainless" in reference to cookware, as in this All-Clad D3 configuration diagram:
Since 0% nickel steel is less corrosion resistant than steel with nickel, it is usually used only on the exterior, with the cooking surface being 18/8, 18/10, or something similar.
There is much more to know about stainless steel as it applies to cookware. Probably the most important thing to understand is that quality can vary greatly even among the same types of stainless steel. This can account for the price differences you often see in the cookware market.
For example, 18/10 stainless steel made in China is often inferior to 18/10 stainless steel made in the USA or Western Europe, and many brands of Chinese clad stainless cookware are priced accordingly. If you want to buy on the budget end, there are only a few brands of Chinese-made clad stainless cookware we recommend. They are Cuisinart Multiclad Pro and Tramontina Tri-Ply Clad. (You can also check out our Cuisinart Clad Stainless review and our Tramontina Tri-Ply Clad review.)
The more you know, the better decision you'll make when buying clad stainless cookware. Our Stainless Steel Cookware Set Buying Guide goes into more detail about stainless steel if you want to learn more.
Is Stainless Steel Cookware Safe?
Yes: clad stainless steel is one of the safest types of cookware on the market.
Stainless steel is durable: a good brand won't rust or corrode. Though it may show some discoloration with use, the steel itself will remain intact indefinitely.
Stainless steel is also stable: it reacts minimally with food (mostly with acidic foods). This is not the case with many other cookware materials, including aluminum, copper, cast iron, and carbon steel, which can sometimes impart metallic flavors. In the case of aluminum, it can even create a potential health risk as some studies have linked aluminum with Alzheimer's disease (though these have been mostly debunked).
Stainless steel can leach small amounts of nickel, chromium, and iron. While some leaching has been detected in scientific studies, the amounts are extremely small and generally considered safe for humans.
The one possible exception is people with nickel allergies (a common type of allergy): stainless steel may leach enough nickel to cause a reaction, so may want to be avoided.
The same studies show that new stainless steel leaches the most, and that after several uses, the amount of leaching decreases to almost zero.
Other than nickel, the chemicals that leach from stainless steel are mostly required by the human body and thus are not dangerous. Even nickel does not leach in amounts unsafe to anybody other than people with an allergy to it. (For these people, there is nickel-free stainless steel cookware such as Chantal Induction 21.)
Every type of cookware has some drawbacks and possible safety concerns. The overall stability of stainless steel makes it one of the safest cookware choices on the market.
Why Is Stainless Steel "Clad" with Other Metals?
As we already mentioned, stainless steel has terrible heating properties: it heats slowly, unevenly, and does not hang onto heat well. In fact, it's so poor that it is considered to be more of an insulator than a conductor of heat.
If you go back to the table above, you can see that the thermal conductivity of stainless steel is only 16 W/m-K, compared to carbon steel's 51 W/m-K and aluminum's 237 W/m-K (never mind copper's W/m-k of over 400!).
You don't need to know what these units mean to see that stainless steel has a much lower heat conductivity rating than other metals used in cookware.
This terrible rating explains why stainless steel is clad to other metals: both aluminum and copper have excellent thermal conductivity, but are reactive with food. Stainless steel is durable, non-toxic, stable and non-reactive.
When All-Clad founder John Ulam invented the metal cladding process, he revolutionized the cookware industry. Clad stainless cookware offers durability and stability along with the excellent heating properties of aluminum and/or copper.
Most people also think stainless steel is easier to care for than carbon steel (and cast iron) because it doesn't need to be seasoned. We talk more about ease of care below.
Stainless steel is not completely without risks, but if you don't have a nickel allergy, it is one of the safest cookware choices on the market.
Does Stainless Steel Heat Better than Carbon Steel?
If you compare the two metals, carbon steel has better thermal conductivity than stainless (though nowhere near that of aluminum or copper), and they have roughly the same heat capacity (i.e., heat retention).
However, there's more to the story if you want to fully understand how the two types of cookware perform.
Thermal conductivity: Because stainless steel is clad to aluminum and/or copper, it takes on the excellent thermal conductivity of these materials. Thus, clad stainless steel heats faster and more evenly than carbon steel.
Heat capacity/retention: Carbon steel and stainless steel retain heat at about the same rate. However, because stainless steel cookware is clad with aluminum and/or copper, it actually has a much lower heat capacity than carbon steel--that is, clad stainless cookware does not hang onto heat for as long as carbon steel. Put another way, clad stainless cookware is more responsive to temperature changes than carbon steel.
This makes clad stainless cookware excellent for cooking tasks where you want speedy heating and responsiveness to temperature changes. This includes sautéing, pan frying, steaming, making sauces, making grains, boiling potatoes and other vegetables, boiling water, making eggs, fish, pancakes, and more.
Add to this that the aluminum/copper layers in clad stainless cookware heat faster and more evenly than carbon steel, and the result is cookware that most people believe is superior to carbon steel.
There are exceptions. The Demeyere Proline skillet has almost 4mm of aluminum, which is enough to retain heat very well (the more mass, the better the heat capacity no matter what the material is), making it a good choice even for high-heat searing.
But most clad stainless is thinner than this, and will gain and lose heat faster than a carbon steel pan.
Does this mean you need both stainless steel and carbon steel in your kitchen? It depends on your cooking style, budget, space, and other considerations. You can certainly make either pan work for any task. But stainless steel is the more versatile material (and no seasoning required), and is our number one choice for best all-around cookware material.
Even so, many chefs who prefer clad stainless like to have a cast iron or carbon steel skillet in their collection for high-heat searing (us included), as well as a carbon steel wok for stir fries. If you want to get away from nonstick egg pans, carbon steel is also an excellent option.
If you want a versatile, multi-purpose pan responsive to temperature changes, good quality clad stainless steel is the right choice.
If you want a pan for high-heat searing, deep frying, and other tasks where heat retention is needed, carbon steel or cast iron is the right choice.
If you want nonstick properties without the dangerous chemicals, carbon steel is a great choice.
You can use both pans for all types of tasks, but you will have better results if you choose the right pan for the job you want it to do.
Is Stainless Steel Lighter than Carbon Steel?
No, but stainless steel cookware is lighter than carbon steel cookware.
Why?
Once again, it's about the cladding. Carbon steel and stainless steel have roughly the same density, thus roughly the same weight. However, stainless steel is typically clad to aluminum, which is much lighter and less dense.
Therefore, clad stainless steel pans tend to weigh less than carbon steel pans of the same size.
And even though copper is actually more dense than steel, the layers are usually thinner--it takes half as much copper to get the same heating performance as aluminum--so stainless clad with copper is usually lighter than carbon steel, too.
Stainless steel and carbon steel weigh about the same, but aluminum is much lighter, so clad stainless is typically lighter than carbon steel pans of the same size. True also for stainless clad with copper even though copper is heavier because less copper is needed for excellent performance.
Is Stainless Steel Nonstick?
As you probably already know, no: stainless steel is not nonstick.
Well-seasoned carbon steel is way more nonstick than stainless steel.
However, you may be surprised to learn that all cooking materials easily release food when used properly. Therefore, having gunky, messy cookware to clean up is more an issue with technique than with material.
So if you use stainless steel "wrong," you can have sticky messes to clean up. But if you use stainless steel right, the pans clean up almost as easily as nonstick--even if you don't use a ton of butter or oil.
The secret is getting the pan to the right temperature before adding oil or food. When you get it to the right temperature, an air pocket forms between the food and the pan--and nothing sticks!
You know the pan is the right temperature when water forms balls and dances across the surface like mercury. Some people call this the "mercury test." It takes some practice to get it right, but when you do, you will be rewarded with stainless steel pans that behave almost like nonstick.
This 6 minute video from Demeyere (our favorite stainless steel cookware brand) shows the technique:
This is a new discovery for us. We have always told people to heat the pan, then add the oil, then add the food, and to let the food form a crust before trying to stir or turn.
While this method works, too, the "mercury test" method is exciting because it means you can cook on stainless steel without fat if you don't want to use it.
That's a game changer!
We tested it, and it really works. How exciting is that?
And even though the video is from Demeyere, the method should work on all stainless steel cookware.
Stainless steel cookware is not nonstick, but with the right cooking technique, it behaves almost like nonstick, and is easy to clean.
Is Stainless Steel Cookware Easy to Care For?
Now that we've shown you how to cook on stainless steel without sticking, we can honestly answer this question with an enthusiastic "yes": stainless steel cookware is easy to care for.
Even when you get do get a sticky mess, which is bound to happen occasionally--especially as you're trying to get the hang of the "mercury test" method--there's no drama involved in cleaning a stainless steel pan. You can use abrasive scrubbies to lift the gunk, you can use cleansers like Barkeeper's Friend, or you can let pans soak and let the hot soapy water do the work.
Stainless steel cookware is durable, so you can clean it however you want to with no worries about damaging the pan.
Whatever method of cooking you use, stainless steel is easy to care for.
When you use the right technique, clad stainless steel cookware cleans up easily, with none of the heat or utensil restrictions of nonstick.

Tips for Cooking with and Cleaning Stainless Steel Pans
Do You Need to Season Stainless Steel Pans?
Seasoning cookware has become all the rage of late, and now many pans, including nonstick and stainless steel, come with instructions to "season before use."
You can season stainless steel cookware, but you don't need to. Here's an easy seasoning method from Epicurious if you want to give it a try.
Note, however, that this is not the same process as seasoning cast iron. You aren't really building layers of polymerized oil as you do on cast iron or carbon steel. You're just coating the pan with a thin layer of oil, which may help food to stick less.
Rather than go to this trouble, ruining the pan's shiny cooking surface in the process, we suggest you follow the mercury test method in the video above, or the heat pan/add oil/heat oil/add food/let food form crust before moving method. Both will result in easy-to-clean pans, no seasoning necessary.
You do NOT need to season stainless steel pans, but some people find it makes them easier to use and clean.
What to Look for When Buying Stainless Steel Pans
There's a lot to consider when buying stainless cookware. We'll cover as many of the basics as we can here.
When buying stainless steel cookware, there are several features to consider. One easy way to know what you're getting is to buy a reputable brand--there are good brands at every budget level, except for the very lowest (we recommend that you don't spend less than about $200 on a 7-piece set).
You also have to decide whether you want a set or open stock and whether you want full cladding or disc cladding; we discuss this more below.
Should You Buy Sets or Open Stock?
Stainless steel cookware is good for most cooking tasks, so you can find almost any type of pan you want in it. This is great, but can make it hard to decide which pieces you need and whether you want a set or individual pieces ("open stock").
Advantages to buying sets:
Advantages to buying open stock:
Our general recommendations for buying cookware are:
Is Full Cladding Better than Disc Cladding?
Clad stainless cookware comes in two basic configurations: full cladding and disc cladding (also called impact-bonded or encapsulated cladding).
Full cladding is just that: the internal layers of aluminum and/or copper go all the way up the sides of the pan, as shown in this All-Clad diagram:
Disc cladding has the aluminum and/or copper layers only on the bottom of the pan. The sides are stainless steel only, as you can see in this Demeyere Atlantis diagram:
The Demeyere diagram also shows the "seam" which is a telltale sign that cookware is encapsulated and not fully clad.
Which type is better quality? High quality cookware comes in both types, as does low quality cookware. So you need to understand more than just if cookware is fully clad or disc clad: you need to understand the configuration of the cladding.
In general, you want enough cladding to provide fast, even heating. For fully clad cookware, that typically means a layer of aluminum at least 1.5mm thick or a layer of copper at least 1mm thick. For disc cladding, you need thicker cladding to get good heating: Atlantis and other top brands can have up to 5mm of aluminum, copper, or both. (As you can see above, Atlantis even has silver in its disc cladding.)
Lower quality brands can have encapsulated bases barely thicker than the walls of fully clad pieces and that don't fully cover the bottom surface, like this:
The thin, small disc can result in poor heating. These types of pans are alright for liquids, but we do not recommend them for skillets, which perform best with either full cladding or a thick disc cladding that covers the entire cooking surface (as in the Demeyere diagram above).
If you come across an incredible "deal" on clad stainless cookware, there's a good chance that it's disc-clad with too-thin cladding that won't provide good heating. If you're not sure, look for the seam.
We have more information in other articles. Check out our Best Stainless Cookware article for more details on sets, cladding, and more.
Full cladding vs. dis cladding is less important than the actual quality of the cladding. You have to do the research to figure out if the cookware is good quality or not.
How Do You Know How Much Aluminum or Copper a Stainless Pan Contains?
It can be hard to know what you're paying for when buying clad stainless cookware because makers often do not disclose the information you need: How thick is the heating core of aluminum and/or copper?
The thickness of the heating core determines how fast, how even, and how responsive your cookware is going to be. It also determines, in large part, how heavy the cookware will be.
Both are important considerations.
We don't know why makers don't provide this information, as it's crucial to your buying decision. However, we at TRK, as well as some other independent reviewers, have actually cut pans open and measured their configuration.
So the best way to know this information, if the maker does not supply it, is to find an independent reviewer who has measured it.
Another way is to go by weight: if cookware is too light, it almost certainly has a too-thin layer of aluminum and won't heat evenly.
We recommend buying only a brand with a known configuration. (This is where we come in.)
It's up to you to decide what's more important to you: weight or performance. If you don't mind heavy cookware, you should go with a premium brand like Demeyere, which has up to 75% more aluminum than All-Clad D3. If you want good performance but also want something lighter, then you should go with All-Clad or an All-Clad knockoff with nearly the same configuration (Tramontina Tri-Ply Clad or Cuisinart Multiclad Pro).
There are some other good options, but these are the most dependable brands we've found that fit the budgets of most buyers.
It can be hard to know what you're paying for in terms of heating core configuration because makers don't supply this information. To buy wisely and know exactly what you're getting, it's best to rely on independent reviewers who have the information (like us).
Don't buy clad cookware without knowing the cladding configuration.

Carbon Steel Vs. Stainless Steel FAQs
Here are some common questions about carbon steel vs. stainless steel cookware.
Which Is More Nonstick, Carbon Steel or Stainless Steel?
Seasoned carbon steel is more nonstick than stainless steel, but both are easy to cook on without too much sticking if you know the right techniques.
Which Is Heavier, Carbon Steel or Stainless Steel?
Usually carbon steel is heavier, but it depends on the brand. Stainless steel usually has an aluminum heating core, which is a light metal, and is usually lighter than carbon steel. But if you buy a brand of stainless steel with a very thick heating core (like Demeyere Atlantis), then it can be just as heavy as carbon steel.
Do Carbon Steel and Stainless Steel Both Need to Be Seasoned?
Carbon steel needs to be seasoned, stainless steel does not. Some people swear by seasoning stainless steel, but it's non-reactive with food whether seasoned or not. Carbon steel must be seasoned to be non-reactive.
Can Carbon Steel Go in the Dishwasher?
No, you have to wash carbon steel by hand, but if it's seasoned well, washing is almost as easy as with nonstick pans.
Can Stainless Steel Go in the Dishwasher?
Most stainless steel cookware can go in the dishwasher, but hand washing usually produces better results and is better for the cookware. Dishwasher detergents are abrasive and can dull the shiny surface of stainless steel cookware.
Which Is More Oven Safe, Carbon Steel or Stainless Steel?
Both carbon steel and cast iron are oven safe up to at least 500 degrees (this may not apply to lids, especially if glass).
If You Could Just Have One, Would You Choose Carbon Steel or Stainless Steel?
If you could have just one of these, stainless steel is the best choice. It is non-reactive with food and doesn't require seasoning, which make it the more versatile choice. It is also durable enough to last for decades.
Final Thoughts: So, Which Makes the Best Cookware, Carbon Steel or Stainless Steel?
Vs:
Both carbon steel and stainless steel make great cookware, but they have different strengths and weaknesses.
Carbon steel requires seasoning, so is not good for acidic foods or liquids (both of which can strip seasoning). But its excellent heat retention makes it great for high heat cooking. When well-seasoned, a carbon steel pan is an excellent replacement for a nonstick skillet if you're trying to get away from Teflon or other nonstick cookware chemicals.
Carbon steel is usually available only as a skillet-type pan or wok, so if you're looking for a matching set, your best bet is clad stainless.
Carbon steel comes in different thicknesses. If you want a light pan, go with a thinner pan (like the Lodge). If you want cast-iron like heat retention, go with a thicker pan (like the Matfer-Bourgeat). For best performance, we recommend the thicker gauge for skillets. Thin carbon steel is fine for woks.
Stainless steel is a little more complicated because its heating performance depends on how much aluminum and/or copper it's clad with. When clad with a good amount of aluminum and/or copper, stainless steel makes versatile, durable cookware great for many cooking tasks. It is also usually lighter than carbon steel because of the aluminum, and available in many more pieces, as well as sets.
However, good quality stainless cookware is more expensive than most carbon steel cookware, often by a lot. But if you're looking for your forever cookware, stainless steel should fit the bill.
In summary, we recommend clad stainless for your daily use, all-around cookware and a carbon steel skillet and/or wok for searing, stir frying, and as a replacement for nonstick pans if you want to move away from those nonstick chemicals.

It sounds like there are a lot of benefits to stainless steel. I need to get a new set of appliances. I'll have to make sure they are stainless steel.
Great reviewing on choosing pans. It's always terrible work. Your post reminds me of the best pan to keep in your collection.
Thanks.
Drawing from the insights on Iupilon, it's worth noting that while stainless steel pans are durable and tolerant to various utensils, they can indeed be scratched by metal utensils. However, these scratches don't affect the cooking process or the pan's functionality. For those who prefer their cookware to remain pristine, opting for silicone or wooden utensils and gentle cleaning products can help prevent scratches.
