USS 5, Type 501, and 5S, Type 502, contain approximately 5% chromium and 0.50% molybdenum. They resist corrosion and oxidation at elevated temperatures and are particularly adaptable to applications in the petroleum refinery industry. Type 502 contains slightly lower carbon and is used for applications where better weldability is required. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness and creep. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, and joining. Filing Code: SS-22.
