Industeel URANUS® 45N+ 22% Cr Austenitic-Ferritic Duplex Stainless Steel
Categories:	Metal; Ferrous Metal; Duplex; Stainless Steel; T S30000 Series Stainless Steel
Material Notes:	Description: URANUS® 45N+ (UR 45N+) is a nitrogen alloyed austenitic-ferritic Duplex stainless steel (22.05), with a minimum PREN value guaranteed of 36 due to over-alloying in Molybdenum and Chromium. This alloy presents higher mechanical and corrosion resistance properties than duplex 22 Cr stainless steels. Its yield strength is about twice that of standard austenitic grades and well in excess of that of nitrogen alloyed austenitics. Operation temperature of UR 45 N+ is generally limited from -50°C to 280°C (- 58°F to 536°F). Lower temperature used particularly for welded structures may also be considered, but needs technical background. Information provided by manufacturer.
