The Super Duplex Steel Stud Bolts S32750 are made up of about 25% chromium, 7% nickel, 4% molybdenum, and nitrogen, all of which boost their corrosion resistance and mechanical strength. They boast impressive tensile strength ranging from 800 to 1000 MPa, with yield strength nearly twice that of standard stainless steels. These bolts also maintain excellent impact toughness and ductility, even in sub-zero temperatures. The advanced alloy composition guarantees remarkable resistance to chloride-induced stress corrosion cracking and localized corrosion, making them ideal for highly corrosive and high-pressure settings.
