MOTUNG is a general-purpose high-molybdenum, low-tungsten type of high-speed tool steel. It was the first molybdenum high-speed steel to be melted commercially. It is one of the least expensive high-steels and has an excellent combination of cutting ability, toughness and finishing properties. Its many uses include drills, cutters, punches, lathe tools and general-purpose applications. This datasheet provides information on composition, physical properties, hardness, and elasticity. It also includes information on forming, heat treating, and machining. Filing Code: TS-362. Producer or source: Cyclops Corporation.
