Garg Steels, a prominent manufacturer and supplier located in Chennai, India, specializes in high-performance Super Duplex Steel Bars and Rods designed for tough industrial settings. These bars are engineered to deliver exceptional strength and corrosion resistance, making them perfect for offshore, chemical, and marine applications. Garg Steels prides itself on precision manufacturing, strict adherence to global quality standards, and the ability to customize dimensions to fit specific client needs. Renowned for their durability and outstanding mechanical properties, the Super Duplex Steel Bars and Rods from Garg Steels are the go-to choice for industries that require materials capable of withstanding both mechanical and chemical stresses effectively.
Super Duplex Steel Bars and Rods are crafted from a well-balanced blend of 22–25% chromium, 4.5–7% nickel, and 3–4% molybdenum, along with nitrogen and manganese. This unique alloy boasts a duplex microstructure that combines ferritic and austenitic phases, providing remarkable strength and corrosion resistance. These bars demonstrate a tensile strength ranging from 750–850 MPa, yield strength between 500–550 MPa, and a good elongation of about 25%. They also exhibit outstanding resistance to chloride stress corrosion cracking, pitting, and crevice corrosion, making them ideal for highly aggressive and corrosive environments.
