CarTech A6, also known as CarTech Vega, is an air-hardening, high-carbon (0.70%), Mn-Cr-Mo, alloy cold-work tool steel. It combines the deep-hardening and minimum size change characteristics of air-hardening tool steels with the simplicity of low-temperature heat treatment possible in many oil-hardening tool steels. This datasheet provides information on composition, physical properties, hardness, and elasticity. It also includes information on forming, heat treating, and machining. Filing Code: TS-803.
