S32750 (UNS S32750) contains about 24–25% chromium, 3–4% molybdenum, 6–8% nickel, and 0.24–0.32% nitrogen. It possesses a tensile strength of ~780–890 MPa and yield strength about 450 MPa. With a PREN rating greater than 37, it provides superior pitting and crevice corrosion resistance in chloride-bearing regions. It also provides high fatigue strength and toughness at sub-zero temperatures. S32750 can be welded with proper techniques, retaining duplex microstructure and structural toughness even in harsh environments.
Super Duplex Steel S32750 bars and rods are made of 25% chromium, 7% nickel, 4% molybdenum, and nitrogen, providing exceptional corrosion resistance Their mechanical properties include high tensile strength (≥795 MPa), good yield strength (≥550). MPa) , remarkable length (≥15%). ) were present. They are adept at resisting pitting, crevice corrosion and stress corrosion cracking even in harsh environments. The main advantages are good strength, good corrosion resistance, good weldability and high temperature tolerance. These properties make them ideal for use in the medical, marine and offshore industries, where durability, durability and resistance to extreme conditions are required.
