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.*INCONEL ALLOY 601GC is a nickel-chromium-iron alloy with additions of aluminum, zirconium, and nitrogen to resist oxidation and micro-alloy, the last to pin the grain boundaries and prevent grain growth at high temperatures. Maintaining finer grain sizes especially helps low cycle fatigue life.
