AL TECH A-HT is a tool steel for difficult cold-work applications. It is somewhat similar to AISI Type A2 in alloy content but with increased wear resistance. Additions of titanium and tungsten produce hard, long-wearing carbides that help to decrease galling and metal pick-up. The main advantages of AL TECH A-HT are: (1) Very high wear resistance, (2) Good toughness, (3) Air hardening and (4) Low distortion in heat treatment. A-HT is used where better wear resistance is required than is attainable using AISI Type A2 or better toughness than AISI Type D2. This datasheet provides information on composition, physical properties, microstructure, hardness, elasticity, and compressive strength as well as fracture toughness. It also includes information on forming, heat treating, and machining. Filing Code: TS-457. Producer or source: AL Tech Specialty Steel Corporation.
