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.Allegheny Ludlum Type 430 (UNS S43000) stainless is a corrosion- and heat-resistant chromium steel. Its oxidation resistance is superior to Type 304 in intermittent service, but somewhat lower than Type 304 in continuous service. Type 430 is magnetic in all conditions.
