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.JESSOP MUSTANG is a tungsten-molybdenum high-speed steel that contains vanadium. It offers excellent cutting ability and, for most applications, its performance excels the tungsten-base (18 tungsten-4 chromium-1 vanadium) high-speed grades. It is often used as a general-purpose high-speed steel. Among its many applications are boring tools, broaches, cutters, drills, end mills, gear cutters, lathe tools, taps, punches and wood-working knives.
