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.REMANIT 4539 is a low carbon corrosion resistant austenitic stainless steel with good levels of chromium, nickel, molybdenum, copper and nitrogen to show good resistance to reducing acids and chloride solutions. It was one of the early alloys used in flue gas desulfurization equipment.
