Garg Steels, a leading manufacturer and supplier located in Chennai, India, specializes in high-performance Super Duplex Steel Hex Bars that are celebrated for their strength, corrosion resistance, and precision. Designed to meet the most demanding industrial standards, these hexagonal bars offer exceptional durability in highly corrosive and chloride-rich environments. With a commitment to quality and reliability, Garg Steels serves a wide range of industries, including marine, chemical processing, and oil & gas. Each product undergoes thorough testing to ensure it meets international standards, establishing Garg Steels as a trusted provider of Super Duplex Steel Hex Bars in India and beyond.
Super Duplex Steel Hex Bars are made up of about 25% chromium, 7% nickel, 4% molybdenum, and a carefully controlled amount of nitrogen, which together provide outstanding strength and corrosion resistance. Their dual-phase microstructure enhances toughness and helps resist stress corrosion cracking and pitting. Typically, these bars boast a tensile strength ranging from 750 to 1000 MPa and a yield strength of around 550 MPa. With excellent weldability and durability, Super Duplex Hex Bars maintain their structural integrity even under high pressure and temperature, making them perfect for aggressive environments and demanding operational conditions.

Super Duplex Steel Hex Bars find extensive use in industries that require exceptional mechanical strength and resistance to harsh conditions. They are commonly utilized in offshore oil rigs, desalination plants, chemical processing facilities, heat exchangers, and marine applications. Their unique hexagonal shape enhances torque transfer and grip in mechanical assemblies. Thanks to their corrosion resistance in seawater and acidic environments, they are ideal for flanges, shafts, fasteners, and high-pressure equipment. Super Duplex Hex Bars are also preferred in structural applications that demand durability, precise dimensions, and low maintenance, especially in sectors where failure is not an option.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
