2507 is a ferritic-austenitic (dual-phase) stainless steel that combines the most beneficial properties of many ferritic and austenitic steels. Due to its high chromium and molybdenum content, the steel has excellent resistance to pitting, crevices and uniform corrosion.
Dual-phase microstructure ensures that the steel has high stress corrosion cracking resistance and high mechanical strength.
2507 stainless steel applications in the oil and gas industry;
Offshore shitaitian oil platform (heat exchanger pipe, water treatment and water supply system, fire protection system, sprinkler system, water stabilization system;
Petrochemical equipment;
Desalination (desalination) equipment (and the high-pressure pipe and seawater pipe in the equipment);
Mechanical and structural components requiring both high strength and high corrosion resistance;
Burning (waste) gas purification equipment.
Main ingredients: 25Cr-7Ni-4Mo-0.27N
SAF 2507 offers high compressive strength, impact strength, low coefficient of thermal expansion and high thermal conductivity.
These characteristics are applicable to many structural and mechanical components.
SAF 2507 has high impact strength and is not suitable for prolonged exposure to temperatures higher than 570°F, which may reduce toughness.
Tensile strength: σb≥ 730MPa;
Elongation: δ≥20%
