With roughly 25% chromium, 7% nickel, 3.5% molybdenum, and 0.2% nitrogen, Super Duplex Steel S32750 is a highly alloyed stainless steel. Excellent resistance to pitting, crevice corrosion, and stress corrosion cracking is provided by this special composition. It has a high yield strength of 550 MPa, a high tensile strength of about 795 MPa, and an elongation of 15–20%. It is appropriate for harsh environments because of the duplex microstructure’s balance of strength and toughness. It is perfect for demanding applications because it also retains exceptional fatigue strength, weldability, and thermal conductivity.
