Jyoti Steels, based in Mumbai, India, is a leading manufacturer and supplier of Super Duplex Steel Tube Fittings, delivering precision-engineered solutions for high-performance fluid and gas systems. These fittings are designed for extreme service environments requiring superior corrosion resistance and mechanical strength. Manufactured to international standards, Jyoti Steels’ tube fittings are trusted in critical applications across industries like oil & gas, chemical processing, desalination, and marine. Backed by robust infrastructure and technical expertise, the company ensures exceptional product quality, reliability, and durability in every component it delivers.
Super Duplex Steel Tube Fittings are primarily composed of Chromium (Cr: 24–26%), Nickel (Ni: 6–8%), Molybdenum (Mo: 3–4%), Nitrogen (N: 0.2–0.3%), Manganese (Mn: ≤1%), Silicon (Si: ≤1%), and Carbon (C: ≤0.03%), with the balance being Iron (Fe). These fittings exhibit tensile strength of 750–930 MPa, yield strength ≥550 MPa, and elongation of around 25%. They provide outstanding resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. Physically, they have a density of 7.8 g/cm³, a melting point near 1350°C, and thermal conductivity around 15 W/m·K, making them ideal for severe service environments.

Super Duplex Steel Tube Fittings are widely used in applications that demand high corrosion resistance and mechanical strength. They are essential components in offshore and subsea systems, chemical and petrochemical processing, desalination plants, and marine environments where chloride exposure is high. These fittings are suitable for hydraulic and instrumentation tubing, piping systems, and process control systems. Their ability to withstand high pressures, temperatures, and aggressive media makes them ideal for oil and gas refineries, power plants, and water treatment facilities. With long service life and low maintenance, they are preferred in mission-critical and safety-sensitive systems.
