Barsham Nickel Alloys, Doha, Qatar, is a renowned manufacturer and supplier of high-quality nickel alloy products and stainless steel. With precision and reliability at the core, we cater to various industries. Our Super Duplex Steel Fasteners S32750 are designed for exceptional strength and excellent resistance to corrosion, especially in high-chloride conditions. These fasteners are well-suited for mission-critical uses in oil and gas, chemical processing, and marine applications. We are dedicated to delivering on time, satisfying customers with efficiency and quality.
Super Duplex Steel S32750 fasteners consist of about 25-30% chromium, 4-6% molybdenum, 7-8% nickel, and nitrogen and are known to be highly resistant against pitting corrosion, crevice corrosion, as well as stress corrosion cracking. The mechanical specification consists of up to 800 MPa tensile strength as well as approximately 550 MPa yield strength, thereby high strength and high durability. Its density is about 7.8 g/cm³ and, therefore, its temperature range remains from -50°C to 300°C. The exclusive duplex microstructure offers superior performance in corrosive environments and, therefore, finds applications in tough applications across sectors such as oil and gas.
