Garg Steels, a well-respected manufacturer and supplier located in Chennai, India, specializes in top-notch Super Duplex Steel Round Bars that are engineered for outstanding performance in harsh and corrosive environments. With a strong emphasis on quality, precision, and durability, Garg Steels delivers round bars that adhere to international standards, catering to a diverse array of industries such as oil & gas, marine, chemical, and power generation. These bars are recognized for their unique dual-phase microstructure, which offers an impressive blend of strength and corrosion resistance. Garg Steels is dedicated to providing timely, reliable solutions tailored to critical applications, all while maintaining competitive pricing.
Super Duplex Steel Round Bars generally contain around 25% chromium, 7% nickel, 4% molybdenum, and a well-balanced amount of nitrogen, which together provide remarkable corrosion resistance and strength. Their dual-phase (austenitic-ferritic) structure enhances toughness and durability. These bars boast a tensile strength ranging from 750 to 1000 MPa, a yield strength exceeding 550 MPa, and commendable impact resistance. Their mechanical stability at high temperatures and resistance to chloride-induced stress corrosion cracking make them perfect for challenging conditions, ensuring long-lasting structural integrity and performance in aggressive chemical and marine settings.

Super Duplex Steel Round Bars find extensive use in critical industries where high strength and corrosion resistance are paramount. You’ll often see them in offshore oil platforms, heat exchangers, desalination plants, chemical processing facilities, and pulp & paper mills. Their exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking in chloride-rich or acidic environments makes them ideal for marine components, valves, shafts, and structural supports. Additionally, these bars are well-suited for pressure vessels and high-load equipment, delivering superior mechanical performance, durability, and longevity in some of the harshest conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
