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.URANUS 52N+ is a chromium super duplex stainless steel with a pitting index equal or greater than 40. Improvements in the composition include optimization of the molybdenum and nitrogen. This is an improved version of URANUS 52N (See Alloy Digest SS-566).
