Ferritic stainless steel is an interstitial solid solution of carbon dissolved in α-Fe with a body-centered cubic structure. It is one of the three kinds of stainless steels that came into being at the beginning of the 20th century, together with martensite and austenitic stainless steels. The traditional ferrite stainless steels contain almost no nickel, with relatively low cost and price, and excellent comprehensive performance, which make them favored by the market.
