Overview of ASTM A276 Super Duplex Steel S32750 Round Bars:

2507 duplex stainless steel is a ferritic-austenitic (duplex) stainless steel. It combines the most beneficial properties of many ferritic steels and austenitic steels. Because the steel contains high chromium and molybdenum, Therefore, it has excellent resistance to pitting corrosion, crevice corrosion and uniform corrosion. The two-way microstructure ensures that the steel has a high resistance to stress corrosion cracking, and the mechanical strength is also high.

2507 stainless steel bars are used in the oil and natural gas industry; offshore rock-breaking oil platforms (heat exchanger tubes, water treatment and water supply systems, fire fighting systems, water spray systems, water stabilization systems; petrochemical equipment; desalination (desalination) equipment (and High-pressure pipes and seawater pipes in equipment); mechanical and structural components that require both high strength and high corrosion resistance; combustion (waste) gas purification equipment.
