CARPENTER HI SHOCK 60 is an air-hardening steel for tools and dies that require extreme shock resistance. Its benefits, in addition to exceptional toughness, include good machinability and a low hardening temperature. Recommended applications include hobs, heavy-duty punches, mandrels and other tools and dies subject to high shock. This datasheet provides information on composition, physical properties, hardness, and tensile properties as well as fracture toughness, and deformation. It also includes information on forming, heat treating, machining, and surface treatment. Filing Code: TS-397. Producer or source: Carpenter.
