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.INCO Alloy G-3 is a nickel-chromium-iron alloy with additions of molybdenum and copper. Some of the minor elements are controlled to provide increased resistance to weld heat-affected zone corrosion. The alloy has exceptional stress-corrosion cracking resistance in chloride-containing environments.
