View Sample Alloy Digest Data Sheet (PDF)Since 1952, Alloy Digest has been the leading reference for materials property data on metals and alloys used throughout the world. Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.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.
