DUPLEX 2507 STAINLESS STEEL PIPE
SUPER DUPLEX 2507 STAINLESS STEEL PIPE is a ferritic-austenitic (biphasic) stainless steel that combines the most beneficial properties of many ferritic and austenitic steels because of their high levels of chromium and molybdenum The ability to resist pitting corrosion, crevice corrosion and uniform corrosion.The biphasic microstructure ensures that the steel has a high resistance to stress corrosion cracking, and the mechanical strength is also high.
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 systems, water stabilization systems; petrochemical equipment; desalination (desalination) equipment High-pressure pipe, sea water pipe); both high strength and high corrosion resistance of the mechanical and structural components; combustion (waste) gas purification equipment. Main components: 25Cr-7Ni-4Mo-0.27N
