2507 is a ferritic-austenitic (duplex) stainless steel. It combines the most beneficial properties of many ferritic steels and austenitic steels. Due to the high content of chromium and molybdenum, the steel has extremely high Good resistance to pitting corrosion, crevice corrosion and uniform corrosion. The dual-phase microstructure ensures that the steel has a high resistance to stress corrosion cracking, and the mechanical strength is also high.

2507 stainless steel is 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 equipment) High-pressure pipes, seawater pipes); machinery and structural parts that require both high strength and high corrosion resistance; combustion (waste) gas purification equipment. Main component: 25Cr-7Ni-4Mo-0.27N

Application areas: pulp and paper industry, seawater desalination, flue gas purification, heat exchangers, chemical tanker piping systems, seawater systems, etc.
