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.The 5 Ni-025 Mo Steel is a new carburizing steel designed for heavy-duty service. It possesses materially higher hardenability in both case and core than any other commercially available carburizing steel free from the processing difficulties associated with the formation of massive chromium carbides.
