HS-220 is a high strength steel designed for minimum tensile strength level of 220,000 psi in the heat treated condition. It exhibits good ductility and impact values consistent with the high hardness. This datasheet provides information on composition, hardness, tensile properties, and bend strength as well as fracture toughness. It also includes information on forming, heat treating, machining, and joining. Filing Code: SA-92. Producer or source: Timken Roller Bearing Company.
