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.SUPERDIE is a superior oil-hardening cold-work die steel of the high-carbon, high-chromium type. It has outstanding wear resistance combined with high hardenability and exceptional size stability. SUPERDIE is especially suited for tools and dies where dimensional limits are close, and high strength and long runs between grinds are necessary. Among its many applications are blanking dies, burnishing tools, beading rolls, lathe centers, plug gages, spinning tools, slitters and punches.
