How To Identify High-Quality Stainless Steel Cookware, And How To Avoid Low-Quality Imitations?

Stainless steel cookware is a great product, and it is one of the most sought-after kitchen appliances in the world. However, many people need to learn how to identify high-quality stainless steel cookware and avoid low-quality imitations. Stainless steel cookware comes in various styles and quality levels in today’s market. While deciding, think about the various coatings and layers that go along with your stainless steel cookware and the pan’s thickness and weight.

In this article, we’ll examine what features to look for in a high-quality stainless steel cooking pan. We’ve done the legwork so you can get started with the correct product; we’ll talk about how to care for your stainless steel cookware to maximize its durability and minimize its reactivity. And we will provide you with some of the most important considerations to remember when you shop for stainless steel cookware.

Can Food Grade Stainless Steel Help Identify High-Quality Stainless Steel Cookware?

The stainless steel used in food equipment must be of the (AISI) 200 series, 300 series, or 400 series to adhere to the NSF International Standard for Food Equipment Material.

Let’s take a closer look at the significance of these sequences.

1. 300 Series

One of the most widespread uses for stainless steel is in kitchenware. 18/10 and 18/8 stainless steel from the 304 class are the most widely used, like All-Clad. These numbers are often found on stainless steel cookware and may perplex you. To understand these, we must first define them.

The first value indicates the chromium concentration, and the second is the nickel concentration. A common combination is 18% chromium and 10% nickel, as in 18/10 stainless steel.

As another example, 18/8 stainless steel consists of 18% chromium and 8% nickel.

There is almost no functional difference between 18/10 and 18/8, and any assertions are only an attempt at upselling.

a. Type 304

Stainless steel type 304 is non-magnetic and belongs to the ‘austenitic’ family of stainless steels.

b. Stainless Steel Type 316

316 stainless is a higher-quality alternative due to the small amount of molybdenum it contains. Almost one-sixteenth to one-eighteen percent chromium, ten to fourteen percent nickel, and two percent molybdenum make up the chemical makeup. Despite its higher price tag, this type of stainless steel offers exceptional corrosion resistance.

2. Series 400

400 series is typically seen in inexpensive cookware like flatware, mixing bowls, and stockpots.

We’ve reached 18/0, which, as we’ve established, consists of 18% chromium and 0% nickel. Flatware from 18/0 stainless steel will be less corrosion resistant or preserve its shine over the years.

The 400 stainless steel series is magnetic because it is a ‘ferritic’ form of stainless steel.

3. 200 series

Production costs are reduced by switching to manganese from nickel in the 200 series. The result is economical stainless steel. While this series is likewise food-grade and safe, it is not high-quality stainless steel and can corrode or rust. This material shares the same lack of magnetic properties as 304.

What To Look More To Identify High-Quality Stainless Steel Cookware

While shopping for cookware, it’s important to verify that it’s constructed of 18/8 or 18/10 stainless steel, the industry standards. You can find these numbers on the bottom of most cookware or the packaging. What should I do if the bottom has no markings? Please have a look at the additional standards that we’ve included.

The Pot’s Heft

A decent quality stainless steel pot will have a particular ‘heft’ that you can feel when you lift it, regardless of whether you get technical about the thickness of the base or the sides and what the ‘correct’ thickness should be.

A heavier pot indicates that more material was utilized in its construction, which implies it was more expensive to produce and will consequently be more expensive for you to buy. The likelihood of hotspots is reduced, and their durability is increased. Food will cook more uniformly as a result of this.

You Can Expect Less Denting With A Heavier Pan

Examine the feedback to see if the pots are mentioned as being heavy or durable.

The Composition Of The Inner Core.

When it comes to transmitting heat, stainless steel needs to be improved. It would be best to search for a set that combines the resilience of stainless steel with the superior heat conductivity of aluminum or copper core or cladding.

A disc at the center of a pan is called a core. Putting up a whole layer along the bottom and sides is called cladding, also known as ‘ply.

Because of the additional metal layers, clad cookware will always cost more than regular cookware. Also, copper-containing cookware will always be more expensive than aluminum-containing options.

Cooking success with stainless steel pans depends on even heat distribution throughout the pan. However, this is conditional on the wall thickness of the copper or aluminum core. A thicker center is better at dispersing heat.

An aluminum core must be thicker by a factor of three to achieve the same heat distribution as a copper core. A pan with an aluminum core will have a more substantial bottom than one copper. Suppose you compare two sets based on weight to measure the pans’ quality. In that case, you should do so only if the pans in each set are of the same material and construction: copper core against copper core, aluminum core against the aluminum core.

Look Into The Following Factors to Avoid Low-Quality Imitations of Stainless Steel Cookware

If your pan has rust, it could be because of one of three things:

The Parts That Make Up The Stainless Steel Cookware:

Nickel-free 18/0 stainless steel is more likely to rust than 18/10 (18% chromium, 10% nickel). The main thing that makes stainless steel not rust is chromium. By definition, stainless steel needs to have at least 10.5% chromium by weight. In the United States, stainless steel that touches food must have at least 16% chromium. The amount of chromium in high-quality 304/316 stainless steel ranges from 18% to 20%. So, a cheaper set that isn’t a brand name might have a low range of chromium, which means that more of the raw steel is prone to rust.

Stainless steel can also rust if it is exposed to too much acidic food, too much harsh scrubbing, or too much salt.

Yet, this idea has a flaw that could improve. One reason is that there is no such thing as a magnetic stainless steel pan, and there’s a solid reason for this:

  • Austenitic (nickel-containing, non-magnetic) stainless steel has exceptional corrosion resistance, making it a great choice for use in a kitchen. Without the nickel to stabilize the metal, the piece would erode and not last very long if made of pure magnetic stainless steel. Would I consider buying an 18/0 stainless steel pan with a magnetic base if it were nickel-free?
  • Some high-quality stainless steel has an outer layer composed of magnetic stainless steel. It needs to be used this way with induction stovetops, which employ a quickly charging electromagnetic field to heat cookware.
  • Manufacturers of high-quality stainless steel use three layers of metal;
  1. The austenite layer of steel on the inside
  2. The ferrite steel on the exterior
  3. And a layer of aluminum in between for optimal heat conductivity (steel alone does not conduct heat evenly). Single layers of austenitic stainless steel are typical of lower-quality stainless steel.
  • Austenitic (non-magnetic) stainless steel comes in a variety of grades. In some cases, the production process will result in austenitic stainless steel having a low magnetic susceptibility.

Suppose you know somebody who has had high-quality stainless steel cookware like Cuisinart for a long period. In that case, you can see that it is quite corrosion-resistant and holds up well over time just by comparing it to low-quality stainless.

To know that your stainless is of the best quality, you need to be a metals specialist and visit the facility where the steel is created to see if their manufacturing technique develops pure austenite without corrosive elements formed. My advice is to start with high-quality stainless steel from a reputable manufacturer.

What Exactly Is The Deal With Magnetic Stainless Steel?

You can use a magnet to determine whether or not a piece of stainless steel is high enough quality. The “magnet test” entails applying a magnet to your stainless steel cookware to see if it sticks; this indicates the absence of nickel and hence the “safety” of the cookware (which is austenite steel). Indeed, steel is not a nickel (austenite) alloy if a magnet does not stick to it.

Yet, the true purpose of this analysis is to determine whether or not the steel is austenitic or whether or not it is a chromium-nickel alloy.

Stainless steel can have three distinct crystal structures:

  • Austenite
  • Ferrite
  • and martensite.

Creating austenite in stainless steel is all about nickel. As a result, both the 18/8 and the 18/10 are austenitic.

What to Do To Keep Stainless Steel Cookware In Good Condition?

Maintenance of stainless steel cookware is much easier than that of coated cookware, but here are some pointers to keep in mind:

  • Use a stovetop temperature in the middle. This results in less food sticking to the stainless steel and easier cleaning removal.
  • Put your pan in water as soon as you cook, but only after it has cooled. Warping can occur if water is added to a hot pan.
  • When the pan has cooled, soak it in hot soapy water. The food should be easily removed when cleaning time comes.
  • Use vinegar and water to clean your pan if you notice any stains or a white deposit.
  • Avoid soaking the pan for long periods. You can trigger the pitting.
  • Keeping acidic foods (like tomato sauce) in a stainless steel pot is not good.
  • Stainless steel doesn’t rust, corrode, or get dirty. But just because it doesn’t stain doesn’t mean it will never rust. Yes, it does leave marks, and yes, it does sometimes rust.


Which stainless steel grade is ideal for cookware?

Generally, high-quality, food-grade stainless steel cookware is found in the 300 series, with 316 being the optimal grade. Also, it would be best to look for the 300-series digits 18/10 and 18/8. The first value represents the proportion of chromium, whereas the second represents the proportion of nickel.

Is there any variety of stainless steel qualities?

As you may have seen, stainless steel grades fall into three categories: austenitic, ferritic, and martensitic. Their structure and makeup determine their classification. Carbon, chromium, and nickel concentrations will vary amongst the three types.

How can one conduct a home test for stainless steel?

When tested for steel, a piece of the material can be ground on a grinding wheel to reveal its true nature by producing a “glow” of sparks, indicating that it is made of steel. The 300-series stainless steel grade is the most common for non-magnetic and spark-producing items.

What is the best stainless steel cookware according to thickness?

All-Clad tri-ply is the thickest standard layer for stainless-steel cookware, measuring in at a whopping 2.6mm and featuring an aluminum layer measuring in at 1.7mm. Longevity and durability are both increased with thicker pots. They’re hefty, but their heat is consistent and lasts long.


Some people with nickel allergies may want to avoid using any stainless steel that is not labeled “nickel-free.” Still, stainless steel is considered a healthy cooking surface because it does not produce off-flavors when exposed to acidic food. Stainless steel is inexpensive, simple to clean, has a high melting point, and does not release toxic fumes when heated, unlike overheated nonstick PTFE materials like Teflon.
