The yield strength of 2205 duplex stainless steel is more than twice that of ordinary austenitic stainless steel. This feature makes the designer reduce the weight when designing products, making this alloy more cost-effective than 316317l. This alloy is particularly suitable for the temperature range of - 50 ° f / + 600 ° F. For applications beyond this temperature range, this alloy can also be considered, but there are some limitations, especially for welded structures.
Application fields:
·Pressure vessel, high pressure storage tank, high pressure pipeline, heat exchanger (chemical processing industry).
·Oil and gas pipeline, heat exchanger and pipe fittings.
·Sewage treatment system.
·Pulp and paper industry classifier, bleaching equipment, storage and treatment system.
·Rotary shaft, press roller, blade, impeller, etc. in high-strength corrosion-resistant environment.
·Cargo box of a ship or truck
·Food processing equipment

2507 is a Ferritic Austenitic (duplex) stainless steel, which combines the most beneficial properties of many Ferritic and austenitic steels. Due to the high content of chromium and molybdenum, the steel has excellent resistance to pitting corrosion, crevice corrosion and uniform corrosion. The duplex microstructure ensures that the steel has high resistance to stress corrosion cracking and high mechanical strength
2507 stainless steel is used in oil and gas industry; Offshore skyshatter 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 high-pressure pipe and seawater pipe in the equipment); mechanical and structural components requiring both high strength and high corrosion resistance; fuel (waste) gas purification equipment.
