The chemical composition of stainless steel


The corrosion resistance of stainless steel decreases with the increase of carbon content, and therefore, most of the stainless steel and carbon content are low, not more than 1.2%, largest Wc (carbon) or even less than 0.03% of some steel (e.g., 00 cr12). The main alloying element in stainless steel is a Cr (Cr), only when the Cr content reaches a certain value, the steel corrosion resistance. Therefore, general Cr stainless steel (chrome) content of at least 10.5%. Stainless steel also contains Ni, Ti, Mn, N, Nb, Mo, Si and Cu elements.
