Duplex 2507（UNS S32750）
2507 is a ferritic-austenitic (duplex) stainless steel, which combines many of the most beneficial properties of ferritic and austenitic steels, and has excellent resistance to spot corrosion, crevice corrosion and uniform corrosion due to the high content of chromium and molybdenum in the steel. The biphase microstructure ensures that the steel has a high resistance to stress corrosion cracking and a high mechanical strength.
