FAGERSTA WKE-45 is a tungsten-molybdenum high-speed steel containing 11% cobalt. It has greater red hardness and more wear resistance than almost any other high-speed steel and has adequate (medium) toughness. It is used mainly for lathe tools (for example, tool bits) where maximum wear resistance and red hardness are required. It is particularly suitable for working very hard and wear-inducing materials, including stainless steels. This datasheet provides information on composition and hardness. It also includes information on forming, heat treating, and machining. Filing Code: TS-317. Producer or source: Fagersta Steels Inc..
