201 304 316 Solid Steel Pipe Stainless Steel Round Bar Mill Surface Stainless Steel Round Rod

Superduplex stainless steels have a very high resistance to localized corrosion in chloride media, combined with a high mechanical strength. The series consists of three grades: UR 2507 (EN 1.4410), UR 2507Cu (EN 1.4507) with addition of copper for enhanced resistance in sulfuric acid media, and UR 2507W (1.4501), with tungsten additions for enhanced localized corrosion resistance. The corrosion resistance of these grades is better than UR 904 and comparable to 6Mo austenitics.
All these steels have a pitting resistance equivalent number, PREN, above 40, and a minimum guaranteed yield strength of 550 MPa, allowing for leaner design in load bearing applications.

The alloy composition, including molybdenum and nitrogen additions, has been optimized to obtain a 50/50 austeno-ferritic microstructure with outstanding corrosion resistance even for heavy plates.
The URANUS 2507 series of duplex grades provide cost-efficient alternatives for a wide range of applications, including offshore, phosphoric and sulfuric acid production as well as flue gas cleaning.
