430 stainless steel, known as "stainless iron" in our stainless steel industry, has good corrosion resistance and better thermal conductivity than austenitic stainless steel. At present, it is mainly used in architectural decoration, some home appliance parts, and fuel burners. Scenarios with normal temperature or high temperature such as components.

However, since the chromium content in 430 stainless steel is much less than that of 304, it is not as good as 304 in terms of hardness. But 430 stainless steel is not food-grade stainless steel at all, and more often than not, stainless steel is made by reprocessing recycled scrap iron, steel, lead and other materials through a series of treatments.

Stainless steel products for food are divided into two categories according to their uses. One is tableware containers, which refer to stainless steel utensils used to hold food, that is, pots, bowls, basins, etc. There is also a class of stainless steel tableware, which is usually tableware such as knives, forks, spoons, chopsticks, etc. that come into direct contact with food.  

430 stainless steel is not food grade, 430 belongs to ferritic stainless steel, with magnetism, known as stainless iron, used to make knives, etc. ). Such as 201 202 301 304 (austenite has good corrosion resistance), so 430 stainless steel is not very safe to make tableware, because 430 stainless steel has poor corrosion resistance.

1. Corrosion resistance 430 stainless steel contains 16.00-18.00% chromium, basically no nickel metal, 304 stainless steel contains more chromium and nickel metal, so the corrosion resistance of 430 stainless steel is not as good as 304 stainless steel. 2. Stability performance 430 stainless steel is in the form of ferrite, 304 stainless steel is in the form of austenite, and 304 stainless steel is more stable than 430 stainless steel. 3. Toughness 304 stainless steel has strong toughness, which is stronger than that of 430 stainless steel. 4. Thermal conductivity The ferrite of 430 stainless steel has better thermal conductivity than the austenite of 304 stainless steel. 5. Mechanical properties 430 stainless steel is added with a stable chemical element titanium, and the mechanical properties of the weld are better than 304 stainless steel.

The main safety concern of stainless steel for food contact is the migration of heavy metals. Under normal circumstances, stainless steel products do not pose a food safety risk during the process of holding, cooking or contacting food. When the heavy metals migrated by stainless steel products in use exceed the limit, it may endanger human health.
