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.

ACI Type HU is an iron-chromium-nickel alloy containing about 60% alloying elements in the iron base. Its high chromium and nickel contents give this grade excellent resistance to corrosion by either oxidizing or reducing hot gases, particularly those containing appreciable amounts of sulfur. This excellent corrosion resistance and its excellent combination of high-temperature strength, resistance to thermal fatigue and resistance to carburization make this alloy especially suited for severe service conditions involving high stress and rapid thermal cycling.
