Super Duplex Steel Bars S32750 are made up of about 25% chromium, 7% nickel, 4% molybdenum, along with small amounts of nitrogen to boost resistance against pitting and crevice corrosion. This well-balanced dual-phase structure provides superior strength and toughness compared to regular austenitic grades. S32750 showcases high yield strength, excellent fatigue resistance, and remarkable performance in environments rich in chlorides and under high pressure. The material also offers good weldability and thermal stability, making it perfect for harsh industrial conditions. Its mechanical properties ensure a long service life and reliability in demanding applications.
