202 stainless steel is an austenitic chromium-nickel-manganese alloy. It has high ductility, good corrosion resistance and excellent toughness in both high and low temperature environments. 202 stainless steel is one of the most widely used 200 series stainless steels. 202 stainless steel stabilizes the austenitic structure by adding nickel and manganese, thereby preventing the formation of harmful phases such as sigma phase or chromium carbide. The high nickel content also improves the steel's corrosion and oxidation resistance at high temperatures.
