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.CRUCIBLE VERSASTEEL is a new type of tool steel with its composition carefully balanced to provide an unusual combination of fine grain structure, high secondary hardness and compressive yield strength, good toughness and exceptional wear resistance. Its resistance to tempering approaches that of high-speed steels.
