UNS S31803 Duplex Stainless Steel Welded Pipe
Product Introduction
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. Seam tube).
Duplex Steel S31803 Welded Tube is a type of tubing made from Duplex Steel Grade S31803. This material combines austenite and ferrite microstructures, offering a unique set of properties. The key features of Duplex Steel S31803 Welded Tube include excellent corrosion resistance, particularly in environments containing chlorides and acidic solutions. It also exhibits high strength, allowing it to withstand demanding conditions.
