Duplex Steel S31803 / S32205 Welded Pipes

S31803 duplex stainless steel is a kind of steel with good corrosion resistance and high strength (yield strength is 2-3 times that of other austenitic steels). The steel contains high chromium and molybdenum, so it has excellent The ability to resist pitting and uniform corrosion. The dual-phase microstructure ensures that the steel has a high resistance to stress corrosion cracking, and the mechanical strength is also high. S31803 duplex stainless steel pipe is a medium-alloy duplex stainless steel with good chloride stress resistance. Medium alloy type-representative grade is UNS S31803 (22Cr-5Ni-3Mo-0.15N); S31803 duplex steel pipe is used in three types of duplex steel (2205 duplex stainless steel pipe, 2507 duplex stainless steel pipe, S31803 duplex stainless steel pipe, and S31803 duplex stainless steel pipe.

Product Details of Duplex 2205 Stainless Steel Welded Pipe


Duplex S31803 / S32205 stainless steel welded pipes



Overview of Duplex S31803 / S32205 Stainless Steel



Duplex stainless steel S31803 / S32205 is a ferritic-austenite stainless steel. S31803 has good resistance to chloride ion stress corrosion cracking. It has better resistance to chloride ion pitting and crevice corrosion than ferritic stainless steel. Ordinary corrosion ability, good resistance to sulfide stress corrosion.


S31803 is developed on the basis of Swedish SAF2205. It is currently the most widely used steel grade in two-way steel in the world. It is resistant to curing hydrogen, carbon dioxide, and chloride environments. It can be formed by hot and cold processing and has good welding performance. Suitable for use as structural material, instead of 304 and 316.


Due to its excellent performance, duplex stainless steel S31803 can be used in: food industry equipment, paper industry equipment, thermal power plant flue gas desulfurization equipment, offshore oil platforms, desalination equipment and other special chemical environmental equipment: oilfield pipelines and equipment, and other chemical equipment. Used in heat exchangers and cold showers and devices for oil refining, fertilizers, papermaking, petroleum, chemical industries, etc., resistant to seawater, high temperature and concentrated nitric acid.
