Super Duplex Steel Flanges S32750 are made up of about 25% chromium, 7% nickel, 4% molybdenum, and nitrogen, all of which contribute to their impressive strength and corrosion resistance. These flanges boast excellent mechanical properties, with tensile strength ranging from 800 to 1000 MPa and yield strength that is nearly double that of standard stainless steels. They also retain outstanding toughness and ductility, even in sub-zero temperatures. Their advanced chemical makeup ensures reliable resistance to chloride-induced stress corrosion cracking and localized corrosion, making them perfect for highly corrosive and high-pressure service conditions.
