Super Duplex Steel S32750 possesses a specially controlled chemical composition that normally consists of 24–26% chromium, 6–8% nickel, 3–5% molybdenum, and nitrogen, manganese, and iron additions. This composition leads to a two-phase microstructure—ferrite and austenite—that offers outstanding resistance to stress corrosion cracking, pitting, and crevice corrosion. The alloy provides high tensile strength of about 795 MPa and yield strength of about 550 MPa, with excellent impact toughness even at subzero temperatures. Its strength, along with good weldability and heat stability, makes it ideal for high-performance and long-term industrial application.
