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.RA 353 MA is a 25Cr-35Ni alloy designed with oxidation resistance and applications above 1800 F in mind. It is fortified with a rare earth element and silicon for oxidation resistance and nitrogen for stability and high temperature strength. Typical applications include radiant tubes and furnace components.
