Elvis Nickel Alloys, based in Houston, USA, stands out as a top manufacturer and supplier of Super Duplex Steel Stud Bolts S32750. These bolts are specifically designed for critical fastening tasks in environments that are both highly corrosive and under significant stress. Crafted from high-quality UNS S32750 (SAF 2507) material, they boast an impressive blend of mechanical strength and corrosion resistance, thanks to their well-balanced ferritic-austenitic microstructure. Built to endure extreme conditions—like those found in chloride-rich and chemical settings—these fasteners are commonly utilized in offshore oil and gas platforms, chemical plants, marine applications, and desalination systems, meeting ASTM A193 Grade B8 and other relevant standards.
S32750 Super Duplex Steel Stud Bolts are made up of 24–26% chromium, 6–8% nickel, 3–5% molybdenum, and 0.2–0.3% nitrogen, along with iron and trace elements such as manganese, copper, and silicon. This unique blend results in impressive yield strength (≥550 MPa), tensile strength (~800 MPa), and elongation (≥25%), ensuring they perform reliably under both dynamic and static loads. The material is particularly resistant to pitting, crevice corrosion, and stress corrosion cracking, especially in harsh environments like seawater and brine.
