2507 is a ferritic-austenitic (duplex) stainless steel. It combines the most beneficial properties of many ferritic steels and austenitic steels. Because steel contains a high chromium and molybdenum content, it has excellent resistance to pitting corrosion, crack corrosion and uniform corrosion The dual-phase microstructure ensures that the steel has a high resistance to stress corrosion cracking, and the mechanical resistance is also high.
Typical 2507 duplex stainless steel microstructure
Stainless steel 2507 is used in the oil and natural gas industry; offshore rock breakwater oil rigs (heat exchanger tubes, water treatment and supply systems, fire protection systems, water spray systems, water stabilization systems; petrochemical equipment; desalination) equipment (and equipment) High pressure pipes, seawater pipes); machinery and structural parts that require high corrosion resistance and resistance; combustion gas purification equipment (waste).
