What is 2507 stainless steel?

USE:
Due to the high content of chromium and molybdenum in the steel, it has excellent 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 Mechanical strength is also high.

2507 stainless steel is used in the oil and gas industry; offshore Shibatian oil platform (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) high-pressure pipes, seawater pipes); mechanical and structural components that require both high strength and high corrosion resistance; combustion (waste) gas purification equipment. Main components: 25Cr-7Ni-4Mo-0.27N
