Ashraf Nickel Alloys stands out as a top-notch manufacturer and supplier of Super Duplex Steel Stud Bolts S32750 in Riyadh, Saudi Arabia. We provide high-performance fastening solutions tailored for critical industrial applications. Crafted from UNS S32750 Super Duplex Stainless Steel, these stud bolts are designed to deliver exceptional strength, corrosion resistance, and dimensional stability, even in the toughest environments. They comply with ASTM, ASME, DIN, and ISO standards and are commonly used in sectors like oil and gas, chemical processing, desalination, and offshore engineering. Thanks to their dual-phase austenitic-ferritic microstructure, they excel at resisting chloride-induced stress corrosion cracking, making them perfect for marine and subsea applications.
Super Duplex Steel S32750 Stud Bolts are made up of 24–26% chromium, 6–8% nickel, 3–4% molybdenum, and nitrogen, which gives them a PREN of over 40 for outstanding pitting and crevice corrosion resistance. They boast a minimum tensile strength of 800 MPa and a yield strength of 550 MPa, along with impressive fatigue and wear resistance. The dual-phase (austenitic-ferritic) structure ensures remarkable toughness, hardness, and resistance to sulfide stress cracking. S32750 stud bolts remain stable in high-pressure and high-temperature settings, making them a preferred choice for fastening in offshore platforms, chemical processing facilities, and structural assemblies.
