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.

AISI Type 446 is a high-chromium (nominally 25%), ferritic, heat-resistant alloy with excellent resistance to oxidation and to various forms of hot corrosion. The alloy is used most commonly for service between 1500 and 2200 F (815 and 1200 C), although its elevated-temperature strength is quite low. Among its many applications are combustion chambers, kiln linings, oil-burner components and annealing boxes.
