AISI Type S7 is a chromium-molybdenum, general-purpose, air-hardening tool steel recommended for uses where shock-resistance, good hot-work properties, good wear resistance, excellent toughness and easy machining are important. These properties make it suitable for many hot-work and cold-work applications. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on forming, heat treating, machining, joining, and surface treatment. Filing Code: TS-297. Producer or source: Tool steel mills.
