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.Originally developed as a high-strength alloy for the aircraft industry, this alloy was further developed and optimized to satisfy the most demanding applications of the mold construction industry. The resulting mold construction alloy, Hokotol, exhibits very high strength and wear resistance, as well as excellent uniformity of strength properties.
