Jyoti Steels is a renowned manufacturer and supplier of Duplex Steel Coils from Mumbai, India. We provide high-quality coils designed to provide excellent corrosion resistance, strength, and durability in numerous industrial applications. Our Duplex Steel coils are produced with the latest technology and rigorous quality checks to meet international standards and specifications. Distributing to the petrochemical, marine, construction, and power generation industries, Jyoti Steels is dedicated to delivering cost-saving, dependable, and timely solutions to satisfy domestic and international customers’ changing needs.
Duplex Steel Coils consist of approximately 22% Chromium, 5–6.5% Nickel, 3–3.5% Molybdenum, and 0.14–0.2% Nitrogen, with Manganese (≤2%), Silicon (≤1%), and Carbon (≤0.03%). These coils possess good mechanical properties, such as a tensile strength of 620–880 MPa and yield strength of about 450 MPa. In terms of physical properties, Duplex steel possesses a density of 7.8 g/cm³ and melting point of about 1350°C. With its two-phase microstructure of ferritic and austenitic content, Duplex steel exhibits fine resistance towards stress corrosion cracking, pitting, and crevice corrosion, and hence is suitable for application in aggressive and chloride-bearing environments.
