In duplex pipe fittings, the ferrite phase and the austenite phase account for about half of its solid solution structure, and the content of the lesser phase generally needs to reach 30%. In the case of low C content, the Cr content is 18%~28%, and the Ni content is 3%~10%. Some duplex pipe fittings also contain alloying elements such as Mo, Cu, Nb, Ti, and N.

As a professional duplex stainless pipe manufacturer in China, Yuhong Group provides quality super duplex tubing solutions. The microstructure of duplex stainless steel pipe for sale is approximately 50% ferrite (body-centered cubic structure) and 50% austenite (face-centered cubic structure) crystal structure. The two phases coexist as a stable mixture, but this is different from two-phase alloys, where one of the two phases appears as a precipitate. The alloying elements in duplex stainless steel tubes are ferritic (eg chromium, silicon, molybdenum) or austenitic (eg carbon, nickel, nitrogen), which means that they favor the formation of the ferritic and austenitic phases, respectively.
