They focus on **Super Duplex Steel Pipes UNS S32750**, which are celebrated for their remarkable strength, resistance to corrosion, and long-lasting durability. These pipes cleverly combine the best features of both austenitic and ferritic stainless steels, making them perfect for tough environments. Bosega offers precision-engineered S32750 pipes in a variety of sizes and finishes, all while meeting international quality standards and serving industries like oil and gas, marine, chemical processing, and infrastructure development.
Super Duplex Steel S32750 boasts a unique dual-phase microstructure, consisting of about 50% austenite and 50% ferrite. Its makeup includes 24–26% chromium, 6–8% nickel, 3–5% molybdenum, and 0.24–0.32% nitrogen, along with trace amounts of manganese, silicon, and copper. This well-balanced composition provides excellent resistance to pitting and crevice corrosion. On the mechanical side, it showcases impressive strength, with a yield strength around 550 MPa, tensile strength close to 800 MPa, and elongation rates between 15–25%, ensuring superior toughness and resistance to stress corrosion cracking.
