Austenitic stainless steel is stainless steel in high temperature and room temperature. The Ni, 8%~10% Cr and C about 0.1%, with a stable austenite structure. Austenitic chromium nickel stainless steel including 18Cr-8Ni and based on the famous Cr, increase Ni content and adding Mo, Cu, Si, Nb, Ti and other elements of the development of high Cr-Ni series steel Austenitic stainless steel is not magnetic and has high toughness and plasticity, but the strength is low, it is impossible to strengthen by phase transformation, which can be strengthened by cold work, such as adding S, Se, Ca, Te and other elements, it is easy to cut.
