ALLOY 00Cr22Ni5Mo3N is one of four grades of duplex stainless steel that were developed and have found wide applications in China since 1980. In oil refinement and the petrochemical processing industries, they have substituted for austenitic stainless steels in many types of equipment, valves, and pump parts. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on high temperature performance, and corrosion resistance. Filing Code: SS-704. Producer or source: Central Iron & Steel Research Institute.
