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.ENDURO AA is a ductile, non-hardening alloy containing 14 to 18 percent chromium with carbon under 0.12 per cent. It has mechanical properties equal to high grade medium carbon steel, with high resistance to general corrosion and oxidation at high temperatures.
