ASTM A790 S32750 Super Duplex Steel Seamless Pipe Water Treatment Equipment
What is S32750 Duplex seamless pipe ?
S32750 consists of 25% chromium, 4% molybdenum and 7% nickel and is a ferrite-austenitic (duplex) stainless steel that combines many of the beneficial properties of ferrite and austenitic steels. Due to the high chromium and molybdenum content of the steel, it has excellent resistance to pitting, crevice and uniform corrosion. The duplex microstructure ensures high resistance to stress corrosion rupture and high mechanical strength. It has an austenitic + ferrite dual-phase organization with a Cr content of 18% to 28% and a Ni content of 3% to 10%. Some steel also contains Mo, Cu, Nb, Ti, N and other alloying elements, with high strength, resistance to pore erosion, corrosion resistance, fatigue resistance, etc., mainly used in oil refining, fertilizer, paper, petroleum, chemical, seawater-resistant, high-temperature concentrated nitric acid equipment.
