2507 (UNS S32750) Super Duplex Round Bar
Our ASTM A276 / A479 / A182-F53 stock ranges from 12.7 to 254.0
2507 Super Duplex Stainless Steel
Super Duplex 2507 has excellent corrosion resistance to a wide variety of media, with outstanding resistance to pitting and crevice corrosion in seawater and other chloride containing environments, with Critical Pitting Temperature exceeding 50°C. Super Duplex 2507 exhibits a low coefficient of thermal expansion and higher heat conductivity than austenitic steels and is suitable for working temperatures up to 300°C.
