Application fields are:
2205 duplex stainless steel pipe is defined as smelting and manufacturing of stainless steel in which the ferrite phase and austenite are 50% each in comparison with the solidified structure. The actual comparative example is that ferrite accounts for 45-55%, and the corresponding austenite accounts for 55-45%. The excellent performance of 2205 duplex stainless steel is ensured by a proper proportion of the two-phase structure.
2205 duplex stainless steel pipe has excellent mechanical properties and corrosion resistance, as well as good weldability, and has a wide range of uses in the oil and gas industry, marine engineering, chemical industry and other industries. The oil and gas industry uses duplex stainless steel materials to lay oil and gas pipelines with a length of more than 850Km, most of which are 2205 duplex stainless steel seamless steel pipes (also some are S31803 duplex stainless steel pipes and 2507 duplex stainless steel pipes); Due to the strong corrosiveness of the natural gas medium, the high-pressure pipelines are made of 2205 duplex stainless steel.
