ALLOY 00Cr18Ni5Mo3Si2 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, these duplex stainless steels 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 as well as forming and joining. Filing Code: SS-702. Producer or source: Central Iron & Steel Research Institute.
