Garg Steels, a reputable manufacturer and supplier located in Chennai, India, focuses on producing top-notch Super Duplex Steel Hollow Bars designed for outstanding performance in tough conditions. These hollow bars are celebrated for their remarkable mechanical strength, resistance to corrosion, and overall reliability, making them a go-to choice in industries like offshore oil and gas, marine, and chemical processing. Garg Steels takes pride in ensuring that every bar is crafted with precision to meet international standards, guaranteeing consistent quality, accurate dimensions, and long-lasting durability. With a strong emphasis on customer satisfaction and efficient logistics, Garg Steels has established itself as a trusted partner for durable stainless steel solutions.
Super Duplex Steel Hollow Bars are generally made up of around 25% chromium, about 7% nickel, 3-4% molybdenum, and nitrogen, resulting in a unique dual-phase austenitic-ferritic microstructure. This combination offers outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking. The bars can achieve tensile strength up to 1000 MPa and yield strength exceeding 550 MPa, along with impressive impact resistance and fatigue strength. Their structural integrity holds strong even under high pressure and extreme temperatures, making them perfect for demanding applications where both mechanical performance and corrosion resistance are essential.

Super Duplex Steel Hollow Bars find extensive use in high-stress and corrosive settings. They are particularly well-suited for offshore platforms, chemical processing facilities, marine shafts, pump sleeves, and heat exchanger tubes. The hollow design not only makes them lighter but also maintains their strength, which is crucial for precision machining, pressure-containing equipment, and hydraulic systems. Additionally, they are ideal for structural components, bridge supports, and valve bodies, especially in saltwater and chloride-rich environments. Their durability, resistance to corrosion, and ability to handle high pressures make them an excellent choice for various applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
