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 7-Mo PLUS is a duplex stainless steel of austenite in a ferrite matrix. It is superior to 300 series stainless steels like types 304 and 316 in strength, corrosion, pitting and stress-corrosion cracking resistance (to chlorides). Typical applications are heat exchangers in the chemical and petrochemical industries.
