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 020 is an austenitic nickel-iron-chromium alloy. Its relatively high nickel content provides resistance to stress-corrosion cracking. Molybdenum gives the alloy good resistance to pitting and crevice corrosion; chromium makes it resistant to oxidation and niobium confers resistance to intergranular attack.
