Jyoti Steels is one of the well-established manufacturers and suppliers of S32750 Super Duplex Steel Fasteners in Mumbai, India. Dedicated to providing high-performance fastening solutions, Jyoti Steels provides fasteners made from S32750 grade with its inherent high strength and superior resistance against corrosion. These fasteners are particularly suitable for severe environments including marine, offshore, and chemical processing plants. Supported by state-of-the-art technology and rigorous quality checks, Jyoti Steels guarantees its Super Duplex S32750 fasteners adhere to international standards, ensuring strength and reliability in extreme industrial uses.
Super Duplex Steel S32750 Fasteners are composed of Chromium (24–26%), Nickel (6–8%), Molybdenum (3–5%), Nitrogen (~0.24–0.32%), and Iron (balance), with trace elements such as Manganese (<1.2%), Copper (<0.5%), and Carbon (<0.03%). These factors offer excellent resistance to pitting, crevice corrosion, and stress corrosion cracking. Mechanically, S32750 fasteners have high tensile strength (~795 MPa), yield strength (~550 MPa), and good ductility with elongation of about 25%. Having a density of 7.8 g/cm³ and thermal conductivity of ~15 W/m·K, they retain excellent strength and corrosion resistance in temperatures up to 300°C.
