Jyoti Steels in Mumbai, India is a topmost manufacturer and supplier of Duplex Steel S31803 Forged Fittings with high strength and corrosion-resistant solutions for critical industrial applications. The forged fittings are precision manufactured according to international standards and find extensive use in aggressive environments where strength, durability, and corrosion resistance are paramount. Jyoti Steels supplies a variety of forged fittings like elbows, tees, couplings, and reducers to industries like oil & gas, petrochemicals, marine, and power. Focused on quality and customer satisfaction, Jyoti Steels supplies to customers in India and worldwide.
Duplex Steel S31803 Forged Fittings consist of about Chromium 21–23%, Nickel 4.5–6.5%, Molybdenum 2.5–3.5%, Manganese <2%, Silicon <1%, Nitrogen 0.14–0.2%, Carbon <0.03%, and Iron as the remainder. These fittings provide tensile strength of 620–880 MPa, yield strength ≥450 MPa, and elongation of 25–30%, making them mechanically strong. The density is approximately 7.8 g/cm³, and melting point is ~1350–1400°C. Duplex S31803 offers good resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. It also offers good weldability and fatigue strength and can be used for high-temperature and high-pressure service conditions.

Duplex Steel S31803 Forged Fittings are extensively applied in oil and gas industries, particularly in offshore platforms, pipelines, and subsea systems because of their resistance to chloride stress corrosion. They are utilized for transferring corrosive fluids in chemical and petrochemical processing plants. These fittings are critical in desalination units, marine environments, and shipbuilding, providing long-term performance in saltwater exposure. They are also employed in power generation systems, heat exchangers, and high-pressure steam lines. Due to the high mechanical strength and superior corrosion resistance, they are a first choice in structurally demanding and corrosive industrial environments.
