Ferritic stainless steel

Ferritic stainless steel is a kind of stainless steel with ferritic structure in use. The chromium content is 11-30%, with body centered cubic crystal structure Sometimes it also contains a small amount of Mo, Ti, Nb and other elements. This kind of steel has the characteristics of high thermal conductivity, low expansion coefficient, good oxidation resistance and excellent stress corrosion resistance. It is mostly used to manufacture parts resistant to atmospheric, water vapor, water and oxidizing acid corrosion

Ferritic stainless steel can be divided into low chromium, medium chromium and high chromium according to the chromium content. According to the purity of steel, especially the content of carbon and nitrogen impurities, ferritic stainless steel can be divided into ordinary ferritic stainless steel and ultra-pure ferritic stainless steel

Ferritic stainless steel grades include 405,409,429,430,439,434, 444 ,439,446,447 etc
