UNS S32750 is a ferritic-austenitic (duplex) stainless steel that combines the most beneficial properties of many ferritic and austenitic steels. Due to the high chromium and molybdenum content of the steel, it has a very high Good resistance to pitting corrosion, crevice corrosion and uniform corrosion. The two-phase microstructure ensures that the steel has a high resistance to stress corrosion cracking and high mechanical strength.
2507 stainless steel used in the oil and gas industry; offshore stone breaking oil platform (heat exchanger tubes, water treatment and water supply systems, fire protection systems, water spray systems, water stabilization systems; petrochemical equipment; desalination (fading) equipment (and equipment) High-pressure pipe, seawater pipe); mechanical and structural components requiring high strength and high corrosion resistance; combustion (waste) gas purification equipment. Main components: 25Cr-7Ni-4Mo-0.27N
UNS S32750, classified as a super duplex stainless steel, has a chemical composition that balances chromium, molybdenum, and nitrogen, with a higher PREN (Pitting Resistance Equivalent Number), ensuring enhanced resistance to aggressive chemicals and high-stress conditions. The high mechanical strength of this alloy reduces the need for heavier materials, contributing to structural efficiency.
