HS-260 is a high strength steel designed for minimum tensile strength level of 260,000 psi in the heat treated condition. It exhibits good ductility and impact values consistent with the high hardness. This datasheet provides information on composition, physical properties, hardness, and tensile properties as well as fracture toughness. It also includes information on high temperature performance as well as forming, heat treating, machining, and joining. Filing Code: SA-117. Producer or source: Timken Roller Bearing Company.
