Jyoti Steels is a leading manufacturer and supplier of S32760 Super Duplex Steel Fasteners located in Mumbai, India. It is well-known for providing corrosion-resistant and high-strength fastening solutions and supplies fasteners made of S32760 grade for applications in aggressive and harsh environments. They are designed according to international standards and are constructed for durability, reliability, and long service life. With robust supply chain and technical capabilities, Jyoti Steels supplies various industries such as oil & gas, marine, desalination, and chemical processing industries in India and worldwide markets.
Super Duplex Steel S32760 Fasteners are made of Chromium (24–26%), Nickel (6–8%), Molybdenum (3–4%), Tungsten (~0.5–1%), Nitrogen (~0.2–0.3%), and Iron (balance), with traces of Copper (~0.5%), Manganese (<1%), and Carbon (<0.03%). These fasteners possess superior resistance to pitting, crevice corrosion, and chloride-induced stress corrosion cracking. They have high tensile strength (~800 MPa), yield strength (~550 MPa), and good elongation (~25%). With a density of 7.8 g/cm³ and thermal conductivity approximately 15 W/m·K, S32760 fasteners retain structural integrity at high-pressure and high-temperature environments.
