ASTM A790 UNS S31260 Duplex Seamless Pipe

                                                  ASTM A790 UNS 31260 Duplex Stainless Steel Pipe DUPLEX is the duplex stainless steel (Duplex Stainless Steel, referred to as DSS), refers to the ferritic and austenitic each accounted for about 50%, generally the content of the lesser phase of the stainless steel needs to reach a minimum of 30%. Duplex stainless steel (DuplexStainlessSteel, referred to as DSS), refers to ferrite and austenite each accounted for about 50%, generally the lesser phase of the content of at least 30% of the stainless steel needs to be reached. In the case of low C content, Cr content in 18% ~ 28%, Ni content in 3% ~ 10%. Some steel also contains Mo, Cu, Nb, Ti, N Some steels also contain Mo, Cu, Nb, Ti, N and other alloying elements. This type of steel both austenitic and ferritic stainless steel features, comp…
