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.NUCLEAR METALS NM-100 is a highly alloyed martensitic steel characterized by excellent resistance to wear and corrosion at temperatures up to 1100 F. It is a powder-metallurgy (P-M) product with a fully dense, wrought structure made possible by a process that includes hot extrusion of canned, pre-alloyed powder. It is used for high-temperature components such as bearings and bushings.
