SUPER STAR is a super high-speed steel capable of being treated to high hardness levels. Its combination of composition and properties facilitates the machining of high-hardness materials and difficult-to-machine superalloys. Excellent hot hardness and wear resistance are obtained in Super Star without loss of edge toughness. This datasheet provides information on composition and hardness as well as deformation. It also includes information on forming, heat treating, machining, and surface treatment. Filing Code: TS-283. Producer or source: Carpenter.
