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.NICROFER 4823 HMo is an austenitic nickel-chromium-iron alloy with increased molybdenum and an addition of copper. The alloy has very good corrosion resistance to a wide range of corrosive media under both oxidizing and reducing conditions. It also has excellent resistance to crevice corrosion, pitting and stress-corrosion cracking.
