Is stainless steel pot harmful to human body?

430 stainless steel is not food grade and is harmless to human body. Food-grade stainless steel is certified according to the national GB9684 standard, and will not produce harmful substances when it comes into contact with food. Moreover, 430 stainless steel does not meet the national standards, so it is not food grade. 430 belongs to ferritic stainless steel, and its corrosion resistance is relatively poor compared with austenite, so it is generally not used for tableware. 430 is generally used as a cutting tool because of its wear resistance and hard texture.

Features of 430 stainless steel:

The requirements of food-grade stainless steel are relatively high, because if the heavy metal content exceeds the standard in the process of holding food, it may endanger people's health. 430 stainless steel is a general-purpose steel with good corrosion resistance. Its thermal conductivity is better than austenite, its thermal expansion coefficient is smaller than austenite, and it is resistant to thermal fatigue. With the addition of stable element titanium, the mechanical properties of welded joints are good. 430 stainless steel is used in building decoration, fuel burner parts, household appliances and household appliances.
