When it comes to composition, **Super Duplex Steel Valves** are typically made from grades like S32750 and S32760, which include about 25% chromium, 7% nickel, 4% molybdenum, and nitrogen. This well-balanced dual-phase microstructure of austenite and ferrite gives them exceptional mechanical strength, with tensile strength ranging from 800 to 900 MPa, along with impressive resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. They also boast excellent toughness, weldability, and oxidation resistance, even at high temperatures, ensuring they perform reliably under extreme pressure and chemical exposure.
