Barsham Nickel Alloys, a Qatar-based company in Doha, specializes in the production and supply of high-quality nickel alloys and specialty metals. We deal in supplying superior nickel alloy and specialty metal products that cater to the strict requirements of various industries like oil and gas, chemical processing, and marine. Our Super Duplex Steel Nuts (S32750) are recognized for their superior strength, corrosion, resistance to high-pressure and high-temperature conditions, etc. With superior pitting and crevice corrosion resistance, we provide timely delivery of all orders, meeting customer specifications with precision and reliability.
Super Duplex Steel Nuts S32750 consist of 25% chromium, 7% molybdenum, 4% nickel, and nitrogen, with the balance being iron. This composition offers superior strength, improved corrosion resistance, and good resistance to pitting, crevice, and stress corrosion cracking. The mechanical properties are a minimum tensile strength of 80 ksi (550 MPa) and yield strength of 50 ksi (345 MPa). Physically, the material is of density 7.8 g/cm³ and melting point of approximately 1350°C (2462°F). These nuts are best suited for application in harsh, high-stress, and high-temperature conditions.
