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 nickel-iron-chromium alloy 801 is a modification of INCOLOY alloy 800. Its nominally 1% titanium content gives it improved tensile and rupture properties. It has excellent oxidation resistance up to 1600-1700 F and can be readily formed and welded.
