Hyderabad-based Dhruv Metals is a leading exporter and producer of high-grade Duplex Steel S31803 Bars and Rods. We are widely known to provide long-lasting, corrosion-resistant duplex steel solutions designed to the stringent needs of sectors like oil and gas, marine, chemical processing, and construction. Our products are specifically designed with accuracy and produced to international standards, which guarantee high performance under extreme conditions. With a focus on quality, dependability, and customer satisfaction, Dhruv Metals has gained a reliable position in the metal manufacturing industry, providing timely supply, reasonable prices, and superior service for all industrial purposes.
Duplex Steel S31803 Bars and Rods contain around 22% chromium, 5–6% nickel, 3% molybdenum, and nitrogen added to enhance strength. This duplex alloy combines austenitic and ferritic steel characteristics, imparting excellent corrosion resistance, especially in chloride-bearing environments. It possesses high tensile strength (to 620 MPa), superior yield strength, good impact toughness, and excellent stress corrosion cracking resistance. The material also exhibits superb pitting and crevice corrosion resistance, superior strength-to-weight ratio, and sound weldability, making it a cost-saving option compared to conventional stainless steels.
