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 STAINLESS No. 7-Mo is a two-phase alloy consisting of a ferritic matrix with pools of austenite. It has high resistance to stress-corrosion cracking and pitting, and good general corrosion resistance in many environments. Its principal use is for tubing and pipe in heat exchangers involving corrosive conditions. It is normally used in the annealed condition for maximum corrosion resistance and ductility.
