2507 is a ferritic austenitic (duplex) stainless steel, which combines the most beneficial properties of many ferritic and austenitic steels. Because the content of chromium and molybdenum in this steel is very high, it has excellent resistance to spot corrosion, crevice corrosion and uniform corrosion The dual phase microstructure ensures that the steel has high resistance to stress corrosion cracking and high mechanical strength
2507 stainless steel is used in oil and natural gas industry; Offshore stone skyshatter oil platform (heat exchanger pipe, water treatment and water supply system, fire protection system, water spraying system, water stabilization system; petrochemical equipment; desalination (desalination) equipment (and high-pressure pipe and seawater pipe in the equipment); Mechanical and structural components with high strength and corrosion resistance are required; Fuel (waste) gas purification equipment. Main composition: 25Cr-7Ni-4Mo-0.27N.
