Stainless Steel for Cookware: What You Need to Know

Stainless steel cookware is a popular choice for professional chefs and home cooks. However, with so many options available, it can be challenging to know which type of them is best suited to you. In this article, we will explore everything you need to know about stainless steel for cookware.

What Is Stainless Steel?

Stainless steel is a type of steel alloy that contains a minimum of 10.5% chromium, as well as other metals such as nickel, molybdenum, or titanium. Steel, which is an alloy of iron and carbon, is highly durable and resistant to warping, scratching, and chipping.

However, it is not very effective at resisting corrosion on its own. To enhance its durability and resistance to corrosion, manufacturers mix chromium with steel to produce stainless steel. When chromium reacts with oxygen, it creates a strong outer layer that is highly resistant to corrosion. The corrosion resistance of stainless steel increases with higher chromium content, while a minimum of 10.5% by weight is necessary for steel to be classified as stainless.

Is Stainless Steel Safe for Cooking?

Stainless steel is generally considered safe for cooking because it is non-reactive and doesn’t leach chemicals or metallic flavors into food. And the first thing to do is to choose cookware that meets the standards, and to choose stainless steel supplier carefully.

Note as well that some grades of stainless steel may contain other elements like nickel, which can potentially cause allergic reactions in some people.

It’s also important to note that while stainless steel cookware is generally safe, it can still pose a health risk if it is scratched or damaged, as this can create areas where bacteria can grow. Additionally, it’s important to follow proper cooking and cleaning techniques to ensure the safety and longevity of your cookware.

1. Food Grade Stainless Steel

Food-grade stainless steel necessitates at least 16% chromium by weight and comprises nickel, enhancing its corrosion resistance, and adding a silver-like luster. This article specifically focuses on food-grade stainless steel. According to the NSF international standard, food-grade stainless steel must belong to the 200, 300, or 400 series, and we will discuss more about this below.

The 300 series is the most well-known type of stainless steel used in cookware and includes 304 and 316 variations.  The 304 series is made of 18/10 or 18/8 stainless steel, indicating the percentage of chromium and nickel respectively.  Both types have similar performance, despite what advertisers may describe.  304 stainless steel is nonmagnetic, nonreactive, and belongs to the austenitic metal family, which contains low levels of carbon and high levels of chromium and nickel, making it the most commonly used food-grade stainless steel. 

On the other hand, 316 stainless steel is less prevalent and contains more molybdenum, which makes it even more corrosion-resistant than the 304 series.  As a result, it is employed in marine environments and biomedical implants. While in everyday cooking, the difference between 304 and 316 stainless steel is not noticeable. The primary distinction is in their corrosion resistance, but for the majority of standard kitchens, there is insufficient humidity or saltwater to make a significant difference. 

The 400 series is made of 18/0 or nickel-free stainless steel and is primarily used for flatware and mixing bowls. It may be less expensive than the 300 series, but it is less durable and less corrosion-resistant. Additionally, it loses its shine more rapidly over time than the 300 series. Although the 400 series is mostly nickel-free, it still contains minimal amounts of nickel at 0.75%. Those with severe nickel allergies may consider other metal types.

Lastly, the 200 series is the lowest-quality option, and usually falls under budget cookware. Instead of nickel, it is made of manganese, which is less expensive but less corrosion-resistant. Nevertheless, it is food safe and non-magnetic. If you have a tight budget but do not want standard aluminum, this may be a good choice.

2. Magnetic(Nickel-free Stainless Steel)

Magnetic (nickel-free) stainless steel is a type of stainless steel without any nickel. It is called “magnetic” because it can be attracted to a magnet, which is different from regular stainless steel that is not magnetic.

Magnetic stainless steel is often used in kitchen utensils because it works on induction cooktops.

One advantage of magnetic stainless steel is its nickel-free composition. which can cause allergic reactions for some people. Additionally, it is more affordable because it is not made of  the expensive metal nickel.

However, magnetic stainless steel may be more prone to rust and stains than regular stainless steel, and may not be as durable over time.

Magnetic stainless steel cookware is a good option for those who are looking for an affordable, nickel-free cookware works on induction cooktops. However, it is important to be aware that it may not be as durable as traditional stainless steel and may require more maintenance to prevent rust and stains.

However, there are some disadvantages to using stainless steel cookware that you should be aware of.

1. Heat distribution. Stainless steel cookware is not the best conductor of heat. It can create hot spots which would lead to uneven cooking. For example, when cooking a steak, the part of the steak on the hot spot of the pan may cook faster than the rest, making the steak unevenly cooked. To avoid this, it’s important to use lower heat settings and to preheat the pan before adding the food.
2. Food sticking Stainless steel cookware can be prone to food sticking to the surface. This is especially true if the cookware isn’t properly preheated or if the food isn’t properly oiled. When food sticks to the surface, it can make cooking certain dishes more challenging. For example, when cooking eggs or pancakes, it can be tough to flip them without sticking. To avoid this, it’s important to preheat the pan properly and to use enough oil or butter.
3. Reactivity Stainless steel cookware can react with acidic foods, causing discoloration or imparting a metallic taste. This can be a problem when cooking dishes with acidic ingredients like ketchup or citrus-based marinades. To avoid this, it’s best to use non-reactive cookware like glass, ceramic, or enamel-coated cast iron for acidic dishes.
4. Maintenance Stainless steel cookware requires regular maintenance to keep it looking and performing its best. It can be prone to scratches and stains, and may require special cleaning products or techniques to keep it in good condition. For example, using abrasive scrubbers or harsh cleaning products can scratch the surface of the cookware, leading to more food sticking and discoloration. To keep stainless steel cookware in good condition, it’s best to clean it with a mild detergent and a soft cloth or sponge.
