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.ALFA-IV alloy is a 20% Cr, 5% Al stainless steel enhanced in oxidation resistance for high-temperature use by the addition of the rare earth metals cerium and lanthanum. The alloy was designed for substrates in industrial and automotive catalytic converters.
