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.INCOLOY alloy 825 is a nickel-chromium-iron alloy with additions of molybdenum, copper, and titanium. It is resistant to chloride-ion stress-corrosion cracking, to pitting and crevice attack, and to corrosion in both oxidizing and reducing media.
