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.VAN CHIP is a tungsten-molybdenum high-speed steel of the M-3 (6-6-3) type containing high carbon and high vanadium. This high carbon and high vanadium content combine to produce superior abrasion resistance for more difficult cutting operations.
