Super Duplex Steel S32760 Pipes and Tubes

Super Duplex Steel S32760 Pipes and Tubes withstand corrosion in a wide range of media, with exceptional resistance to pitting and crevice corrosion in saltwater and other chloride-containing environments. Toughness, high strength, and corrosion resistance in a wide range of organic and inorganic acids are among the properties of Super Duplex Steel Tubes. It contains 25% chromium(Cr), 4% molybdenum(Mo), and 7% nickel(N). It includes around 40-50 percent of different iron oxides when annealed. This is a alloyed super duplex SS that has excellent pitting resistance that is suitable for usage in harsh situations. This super duplex grade microstructure is ferritic and austenitic. It is resistant to stress cracking induced due to chloride, which occurs in normal grades of stainless steel. In sour gas fields, it is also particularly resistant to sulfide-induced stress corrosion cracking.
