How much chromium is stainless steel?
Stainless steel Cr chromium content of at least 10.5%. The main alloying element in stainless steel is Cr chromium, and only when the Cr content reaches a certain value, the steel has corrosion resistance. The corrosion resistance of stainless steel decreases with the increase of carbon content, therefore, the carbon content of most stainless steel is low, the maximum is not more than 1.2%, and some steel ωc, that is, the carbon content is even lower than 0.03%, such as 00Cr12. Stainless steel also contains Ni, Ti, Mn, N, Nb, Mo, Si, Cu and other elements. Stainless steel is most suitable for hospitals or other areas where sanitary conditions are critical, such as: food processing, catering, brewing and chemical industry, not only because it is easy to clean every day, sometimes using chemical cleaning agents, but also because it is not easy to breed bacteria. The test shows that the performance in this respect is the same as that of glass and ceramics. The main factors affecting stainless steel corrosion: 1, the content of alloying elements Generally speaking, the content of chromium in 10.5% steel is not easy to rust. The higher the content of chromium nickel, the better the...
