Detailed Product Description

S32205,2205,F60,022Cr23Ni5Mo3N,EURONORM 1.4462 - X2 Cr Ni Mo N 22.5.3

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.The high chromium and molybdenum content, coupled with the nitrogen addition in 2205, provides general corrosion, pitting, and crevice corrosion resistance superior to 316L and 317L.2205 demonstrates superior erosion-corrosion resistance when compared to 316 stainless steel. It is not subject to intergranular corrosion in the as-welded condition. 2205 may be successfully machined by conventional methods.

The (UNS S32205) grade is a restricted-chemistry version which maintains chromium, molybdenum and nitrogen at higher levels than the (UNS S31803) composition.

Due to its excellent corrosion resistance, 2205 is a suitable material for service in environments containing chlorides and hydrogen sulfide. It is also suitable foe use in dilute sulfuric acid solutions and for handling organic acids, i.e., acetic acid and its mixtures.Oil and Gas Production Down-hole piping, gathering line pipe, CO2 tertiary recovery piping, oil-gas separators, heat exchangers.Chemical Processing Heat exchangers, pressure vessels, tanks, columns, pumps, valves, piping.Transportation Tank trailers, ocean-going tankers, barges.Pulp & Paper Pulp digesters;Power Industry Feedwater heaters, coolers, flue gas scrubbers.Marine Service Sea water piping, pumps.
