2507 Duplex Stainless Steel UNS S32750 DIN/EN 1.4410 F53 SAF 2507

It is a ferritic-austenitic (duplex) stainless steel that combines the most beneficial properties of many ferritic and austenitic steels and has excellent properties due to its high chromium and molybdenum content. Excellent resistance to pitting corrosion, crevice corrosion and uniform corrosion. The bidirectional microstructure ensures that the steel has high resistance to stress corrosion cracking and high mechanical strength.

Stainless steel is used in the oil and gas industry; offshore Shipotian oil platforms (heat exchanger tubes, water treatment and water supply systems, fire protection systems, water spray systems, water stabilization systems; petrochemical equipment; desalination (desalination) equipment (and equipment in High-pressure pipes, seawater pipes); mechanical and structural components that require both high strength and high corrosion resistance; combustion (waste) gas purification equipment.
