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.Soleil A2 is a 13% Cr martensitic stainless steel that is quenched and tempered with properties dependent on the heat treatment. The alloy has improved corrosion resistance over chromium-manganese steels.
