Super Duplex Steel S32750 pipe fittings from Harry Fittings are crafted from a nitrogen-enhanced duplex stainless steel that contains around 24–26% chromium, 6–8% nickel, 3–5% molybdenum, along with balanced amounts of nitrogen, manganese, and iron. This unique composition delivers impressive mechanical strength, boasting high tensile strength (~800 MPa) and yield strength (~550 MPa), which is nearly double that of standard austenitic stainless steels. These fittings also offer exceptional resistance to chloride-induced stress corrosion, pitting, and crevice corrosion. Each fitting adheres to ASTM A815 standards and undergoes rigorous testing to ensure mechanical integrity, dimensional accuracy, and corrosion resistance even in extreme service conditions.
