Super Duplex Steel Stud Bolts S32760 are made up of about 25% chromium, 7% nickel, and 3.5% molybdenum, along with tungsten and nitrogen to boost corrosion resistance. They showcase impressive mechanical properties, with tensile strength ranging from 800 to 1000 MPa and yield strength that is nearly double that of standard stainless steels. These bolts retain excellent toughness and impact resistance, even in low-temperature conditions. The advanced composition of the alloy ensures strong resistance to chloride-induced stress corrosion cracking and localized corrosion, making them ideal for fastening in highly corrosive and high-pressure settings.
