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.CROMO-N tool steel is a low-carbon, high-chromium grade, specially developed to provide optimum resistance to heat-checking during service at elevated temperatures. It is recommended for aluminum die casting dies, extrusion press tooling, aluminum and copper forging dies, and mandrels for extruding all non-ferrous materials.
