AIRKOOL-S is a sulfur-bearing air-hardening tool and die steel intermediate in abrasion resistance between the oil hardening and high-carbon high-chromium types. It is recommended for applications which call for toughness and fairly high abrasion resistance along with good machinability. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on forming, heat treating, machining, and joining. Filing Code: TS-231. Producer or source: Crucible Materials Corporation.
