Super Duplex S32760 stud bolts contain around 25% chromium, 7% nickel, 3.5% molybdenum, 0.3% nitrogen, and small amounts of tungsten. This combination provides strong mechanical properties and good corrosion resistance. They have a tensile strength of about 800 to 1000 MPa and a yield strength between 550 and 750 MPa. These bolts resist pitting, crevice corrosion, and stress corrosion cracking. Their high mechanical stability, along with strong fatigue resistance and toughness, makes them suitable for chloride-rich and high-stress environments, such as offshore platforms and subsea pipelines.
