RED CUT SUPERIOR is a high-speed steel of the 18% tungsten-4% chromium-1% vanadium type. Many consider it to be the best type of high-speed steel for general purposes. It is comparatively easy to fabricate and simple to heat treat. It has a minimum tendency to decarburize and an excellent combination of cutting ability and toughness. Its many uses include drills, reamers, milling cutters, lathe tools, punches, dies and springs for use at elevated temperature. This datasheet provides information on composition, physical properties, hardness, tensile properties, and compressive strength as well as fracture toughness. It also includes information on forming, heat treating, and machining. Filing Code: TS-355. Producer or source: Teledyne Vasco.
