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.Armco 434 is a ferritic stainless steel with good corrosion resistance to mildly corrosive environments and the atmosphere. The alloy is oxidation resistant at temperatures up to 871 C (1600 F) for intermittent service and up to 788-816 C (1450-1500 F) for continuous service. It is used for automotive trim and other exterior environments.
