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 803 is a new high-temperature corrosion-resistant, nickel-iron-chromium alloy, developed by Inco Alloys International for pyrolysis in high-severity ethylene furnaces, and for other petrochemical applications where high levels of oxidation-, carburization-, and/or sulfidation-resistance are important.
