321 stainless steel is a material with excellent high temperature stress fracture performance and high temperature creep resistance, and its stress mechanical properties are better than 304 stainless steel. 321 austenitic stainless steel has good corrosion resistance in the atmosphere and is widely used in petrochemical, electric power, bridge, automobile and other industries. Industry applications:
It is applied to outdoor machines with high requirements for grain boundary corrosion resistance in chemical, coal and petroleum industries, heat-resistant parts of building materials and parts with difficulty in heat treatment.
