What Is The Difference Between 2507 Stainless Steel Pipe And 2205 And 2206 Stainless Steel Pipe?

What is the difference between 2507 stainless steel plate and 2205 and 2206? 2507 stainless steel tube is a ferritic - austenitic (duplex) stainless steel, which combines many of the most beneficial properties of ferritic and austenitic steels. Due to the high content of chromium and molybdenum in the steel, it has excellent resistance to spot corrosion, gap corrosion and uniform corrosion. The bidirectional microstructure ensures that the steel has high stress corrosion cracking resistance and high mechanical strength.

2507 stainless steel pipe used in the oil and gas industry; Offshore Oil platform (heat exchanger pipe, water treatment and water supply system, fire fighting system, sprinkler system, water stabilization system; Petrochemical equipment; Desalination (desalination) equipment (and high pressure pipe in the equipment, seawater pipe); Mechanical and structural components with high strength and high corrosion resistance are required; Burning (waste) gas purification equipment.
