Is 430 stainless steel food grade?

Posted by Admin

430 stainless steel is not food grade, and 430 belongs to ferritic stainless steel with magnetism. It is well known as stainless iron and is used to make tools (wear-resistant and hard). At present, austenitic stainless steel (without magnetism or with micro magnetism) is generally used for cooking utensils, such as 304, 201, 202 and 301 (austenitic has good corrosion resistance)

430 stainless steel is called "stainless steel" in the industry because it is a kind of ferritic stainless steel with good corrosion resistance and superior thermal conductivity than austenitic stainless steel. At present, it is mainly used in building decoration, some Stainless Steel Cookware, fuel burner parts and other normal or high temperature scenarios.

However, the chromium content in 430 stainless steel is much less than 304, so the hardness is not as good as 304. Such a ferritic stainless steel is inferior to 304 stainless steel in terms of corrosion resistance at first, and its performance indicators do not meet the national listing standard for food grade stainless steel. In any way, 430 stainless steel is not food grade stainless steel, and more often, Aluminum Cookware Manufacturers process recycled scrap iron, steel, lead and other materials through secondary remelting, It is made through a series of processing.

Comparison between 304 stainless steel and 430 stainless steel:

1. Corrosion resistance: 430 stainless steel contains 16.00-18.00% chromium, basically no nickel metal. 304 stainless steel contains more chromium and nickel metals, so 430 stainless steel has less corrosion resistance than 304 stainless steel.

2. Stability: 430 stainless steel is ferritic, 304 stainless steel is austenitic, and 304 stainless steel is more stable than 430 stainless steel.

3. Toughness: 304 stainless steel has very strong toughness, which is stronger than 430 stainless steel. 3. Thermal conductivity: 430 stainless steel ferrite has better thermal conductivity than 304 stainless steel austenite.

4. Mechanical property: 430 stainless steel is added with stable chemical element titanium, and the mechanical property of weld joint is better than 304 stainless steel.

304 stainless steel and 430 stainless steel have their own advantages. 430 stainless steel has good thermal conductivity and mechanical properties. 430 stainless steel is better in building decoration, fuel burner parts, household appliances, household appliances and other fields;

304 stainless steel has strong toughness and corrosion resistance. In industries that need corrosion resistance such as industry, food, tableware and medical treatment, 304 stainless steel is better.
