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.Carpenter Custom 465 stainless steel is a newly developed age-hardenable martensitic alloy with less sensitivity to process parameters than other similar alloys. It develops high strength along with fracture toughness and resistance to stress-corrosion cracking.
