Jyoti Steels is a well-known manufacturer and supplier of Duplex Steel S31803 Bars in Mumbai, India. Renowned for producing high-quality industrial steel products, Jyoti Steels provides S31803 bars that confer an optimal balance of strength, corrosion resistance, and durability. These bars are produced in strict compliance with international standards and are well suited to their use in harsh environments. With state-of-the-art manufacturing facilities and customer satisfaction as their prime focus, Jyoti Steels supplies various industries like oil & gas, marine, petrochemical, and construction with reliable material solutions for high-criticality engineering and structural applications.
Duplex Steel S31803 Bars consist of Chromium (21–23%), Nickel (4.5–6.5%), Molybdenum (2.5–3.5%), Nitrogen (0.14–0.20%), Manganese (≤2%), and the balance Iron. The chemical composition has a high degree of resistance to stress corrosion cracking, pitting, and crevice corrosion. The bars have high mechanical strength with tensile strength of around 620 MPa, yield strength of 450 MPa, and elongation of 25%. The bars are physically dense with a density of 7.8 g/cm³ and melting point of around 1400°C. These features render Duplex S31803 bars suitable for use in processes that demand high strength and ability to withstand corrosive environments, particularly in conditions rich in chlorides.
