Adinox Overseas is a leading manufacturer, exporter, and supplier of premium-quality Super Duplex S32750 Round Bars, known for their superior strength, corrosion resistance, and durability. These round bars are produced in accordance with ASTM A276 specifications and are designated under the universal standard number UNS S32750.
With outstanding mechanical properties and enhanced resistance to pitting, crevice corrosion, and stress corrosion cracking, Super Duplex S32750 bars are widely used in demanding applications across offshore, marine, oil & gas, and petrochemical industries.The chemical composition of Super Duplex S32750 includes high levels of chromium, molybdenum, and nitrogen, which contribute to its dual-phase microstructure and improved strength over standard austenitic or ferritic grades.
This unique microstructure gives the round bars excellent resistance to chloride-induced stress corrosion, making them an ideal choice for coastal and subsea applications. Additionally, these bars exhibit excellent weldability and high impact strength, even in cryogenic temperatures, allowing their use in structurally critical and highly corrosive environments.
At Adinox Overseas, our Super Duplex S32750 round bars are available in a wide range of sizes and lengths, customized to meet client-specific requirements. These bars undergo strict quality control checks and are tested for parameters such as hardness, tensile strength, elongation, and surface finish, ensuring the delivery of high-performing, defect-free products. Our bars comply not only with ASTM A276 but also with other international standards such as ASTM A479, ASME SA276, and EN 10088-3.
