Product Description

DUPLEX 2205 STAINLESS STEEL PIPE

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.

Welding performance
 
The line thermal tendency coefficient is small, need not preheat before welding, do not need heat treatment after welding, can be welded with 304 stainless steel
In principle, no welding and preheating should be done
Welding is prone to high temperature cracks
