Austenitic stainless steel is a stainless steel with austenitic tissue at normal temperature. Steel has a stable austenitic tissue when containing about 18% Cr, Ni 8%~25%, and about 0.1% C. Austenitic stainless steel is not magnetic and has high toughness and plasticity, but has low strength, cannot be strengthened by phase transition, can only be strengthened by cold processing, such as adding S, Ca, Se, Te and other elements, it has good easy cutting.
