Abstract

AL-7 is a general-purpose air-hardening tool steel having exceptional toughness coupled with good resistance to softening at moderately high temperatures. This combination of properties makes it suitable for many hot-work and cold-work applications. This datasheet provides information on composition, physical properties, hardness, and elasticity as well as fracture toughness. It also includes information on forming, heat treating, machining, joining, and surface treatment. Filing Code: TS-282. Producer or source: Allegheny Ludlum Corporation.
