High Quality Duplex 2205 Quenching Hollow Stainless Steel Pipe

Duplex 2205 stainless steel pipe with excellent mechanical properties and corrosion resistance, and good weldability, in oil and gas industry, Marine engineering, chemical industry and other industries have a wide range of USES. Oil and gas industry at present USES duplex stainless steel material laying of oil and gas pipeline length has more than 850 km, the vast majority of the 2205 duplex stainless steel seamless steel tube (there is also a part of S31803 duplex 2205 stainless steel pipes, 2507 duplex stainless steel pipe tube); Due to the corrosive strength of the natural gas medium, the high-pressure duplex 2205 stainless steel pipe line materials.

DUPLEX 2205 STAINLESS STEEL PIPE PERFOMACE AND COMPARISON

Duplex 2205 stainless steel pipe combination of ferrite and austenite is the most beneficial properties, has the very good resistance to chloride stress corrosion cracking, is made up of 21% chromium, 2.5% nitrogen and 4.5% molybdenum nickel alloy consisting of duplex stainless steel, it is the yield strength of austenitic stainless steel double, this feature enables designers when designing products lose weight, make this kind of alloy has the advantages of more than 316,317L. Due to the high levels of chrome and molybdenum, the ability to resist spot corrosion and uniform corrosion is excellent. The double phase microstructure ensures that the steel has high tensile strength and high mechanical strength.
