Super Duplex Steel Bolts Manufacturer in Mumbai, India

Super Duplex Steel Bolts consist of Chromium (24–26%), Nickel (6–8%), Molybdenum (3–5%), Nitrogen (~0.2–0.3%), and Iron (remainder), along with traces of Copper (~0.5%), Manganese (<1.2%), and Carbon (<0.03%). Such composition provides the bolts with remarkable pitting resistance, crevice corrosion resistance, and stress corrosion cracking resistance. The bolts have superior tensile strength (~800 MPa), yield strength (~550 MPa), and elongation of approximately 25%. Physically, Super Duplex bolts possess a density of 7.8 g/cm³ and thermal conductivity of ~15 W/m·K and can withstand mechanical strength at high-pressure and high-temperature conditions.
