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.HAMPDEN is an oil-hardening, high-carbon, high-chromium die steel with excellent wear resistance. It hardens with very little change in size or shape. It has very high compressive strength and mild resistance to corrosion because of its high chromium content.
