Abstract

AL TECH APACHE is an air-hardening, cold-work die steel that exhibits less distortion during heat treatment than water or oil-hardening steels and most high-alloy, air-hardening die steels. Its low-distortion characteristic makes it particulary attractive for applications where close size tolerance is important, such as master hubs, trim dies, molds for plastics, bending tools, notching dies and coining dies. 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, and joining. Filing Code: TS-472. Producer or source: AL Tech Specialty Steel Corporation.
