Different types of stainless steel in the restaurant (2020)

The perfect material for our restaurants

Stainless steel is an alloy of several different types of metal that, when combined, is stronger and more durable than when separated. By adding and subtracting various elements to stainless steel, engineers have been able to create many different varieties of the alloy, each with its own characteristics and uses.

Stainless steel is a versatile metal and can be used for many different things, from construction to construction equipment. kitchen. Many different types of stainless steel grades are used in food service establishments, and each type has its own pros and cons. In order to make an informed decision when purchasing food grade stainless steel equipment, you need to understand the main elements of the alloy, the different classification systems and the main types of stainless steel.

Important terms and elements

When describing different types of food grade stainless steel and its properties, there are some key terms and elements that appear regularly. Here are some definitions of what those terms mean and what kind of effect those elements will have on steel.


    • Stainless steel: stainless steel is a durable and affordable metal that is used for a wide variety of purposes. It is strong, making it perfect for construction purposes, and it is corrosion resistant, so it can last a long time without being replaced or broken.

    • Corrosion: Corrosion describes the natural process in which stainless steel breaks down into a more chemically stable form. The most common and best known form of corrosion is rust. Stainless steel is inherently more resistant to corrosion than other metals, but eventually corrodes. There are factors that can also accelerate corrosion, such as exposure to salt, excess moisture, or strong acids.

Stainless steel

  • Alloy: An alloy is a metal that is made by combining various types of metal. For example, stainless steel is not found naturally, but is made by combining iron, carbon, and other metals.

  • Element: "Element" is a chemical term that refers to atoms that have the same number of protons. Elements are the most basic form of substances, and they combine to form an alloy. Some common elements that you may have heard of are oxygen, carbon, nitrogen, and iron.


  • Chrome: Chrome is an essential element for stainless steel, and helps make steel resistant to staining, fogging, and corrosion.

  • Nickel: When nickel is added to stainless steel, it brings stability and strength to the metal. Another benefit of adding nickel to food grade stainless steel is that it makes the steel shiny and shiny, which is an essential quality for cutlery.

  • Carbon: Adding carbon to stainless steel hardens and strengthens the steel and reduces wear. High carbon food grade stainless steel is often used to make chef knives as the knives must be strong, durable, and able to retain a sharp edge.

Benefits of food grade stainless steel in the food service industry

1. Corrosion resistance: stainless steel is especially resistant to corrosion and oxidation compared to other metals, making it perfect for use in kitchen. Food grade stainless steel is often used for equipment kitchen, which is expensive to replace. But since most grades of stainless steel are highly resistant to corrosion, you won't have to worry about replacing your equipment as often.

2. Resistance- Food grade stainless steel is sturdy, and is an excellent material for use in heavy equipment or on shelves for areas of storage.

3. Ease of cleaning: Other materials, such as wood or plastic, have grooves or openings where bacteria can invade and grow. Stainless steel is smooth and doesn't provide a place for bacteria to hide, allowing you to easily clean them, which is an essential benefit for food service.

4. Non-reactive surface: Stainless steel is a nonreactive metal, which means you can use it to cook acidic foods like citrus, tomatoes, and vinegar. Other metals, such as aluminum and iron, are reactive and cooking acidic foods in these metals will affect the taste and damage the metal surface.

Stainless steel grades

There are many different types of stainless steel, and the differences can vary greatly between types. To better differentiate between the different types of stainless steel, they are divided into degrees. There are many different classification systems that are used by different countries and in different settings. For the food service industry, there are two grades of stainless steel that you need to know better, which are SAE grades and cutlery grades.

  • SAE Grades: This classification system is implemented by SAE International, an organization of engineers that develops standards for professionals in various manufacturing industries. To distinguish between stainless steel grades, your system uses integers to classify the different types. You can also see this classification system called the AISI system, which refers to the American Institute of Iron and Steel, which originated this system, although it is now updated and regulated by SAE International.

  • Cutlery grades- Another system for organizing stainless steel grades in the food service industry is the cutlery grading system. This system uses ratios such as 18/0, 18/8, and 18/10 to describe nickel and chromium levels in food grade stainless steel. Chromium and nickel are the two most important elements for cutlery, as they affect the corrosion resistance, shine and magnetism of steel.

Another ratio you can find is 13/0, which is used to make most food grade stainless steel dessert and dinner knives. 13/0 stainless steel is softer than other grades of stainless steel, so manufacturers can add serration to the blade. And while this classification system is typically used to describe cutlery, it can also be used to describe some pots, pans, and other types of utensils. kitchen made of food grade stainless steel.

What are the main types of stainless steel?

There are over 150 varieties of stainless steel, and each of them has different properties, so it is important to understand their variations. In the industry of restaurantsIt is also especially important to distinguish between the various types because a type of food grade stainless steel may be more suitable for a particular task.

For example, if you are buying utensils from kitchen that will come in contact with very salty foods, a pot made of 316 stainless steel is probably better than 304 due to its superior corrosion resistance. Understanding the differences between grades and types of food grade stainless steel can help you make sure you take strategic informed and buy the best products to meet your needs.
