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 19-9 DL has been designed primarily for oxidation and corrosion resistance in service up to 1250 F. It is an austenitic stainless steel and, as with all such materials, is not hardenable by heat treatment. When higher is required, the alloy is] hot-cold worked.
