2507 duplex stainless steel contains 25% chromium, 4% molybdenum and 7% nickel. It has high strength and corrosion resistance and is mainly used in chemical processing, petrochemical and subsea equipment. Also, it has excellent resistance to chlorine corrosion, high thermal conductivity and low coefficient of thermal expansion. In addition, higher mesh.
Molybdenum and nickel content also provide good resistance to pitting, crevice and uniform corrosion.
The impact strength of 2507 duplex stainless steel is also high. 2507 stainless steel should not be used for long periods of time in temperatures above 570°F, which will reduce the toughness of the stainless steel.
2507 is a ferritic-austenitic (duplex) stainless steel that combines many of the most favorable characteristics of ferritic and austenitic steels. It has excellent resistance to pitting, crevice and uniform corrosion due to the high content of chromium and molybdenum. The duplex microstructure ensures that the steel has a high resistance to stress corrosion cracking and high mechanical strength.
2507 stainless steel is used in the oil and gas industry; offshore Hippolyte oil platforms (heat exchanger tubes, water treatment and supply systems, fire-fighting systems, water spray systems, water stabilization systems; petrochemical equipment; desalination (desalination) equipment (and high-pressure pipes in equipment, seawater pipes); machinery and structural components requiring both high strength and high corrosion resistance; combustion (exhaust) gas purification equipment. Main components. 25Cr-7Ni-4Mo-0.27N
