Chuck Metals stands out as a top manufacturer and supplier of Super Duplex Steel Round Bars in Singapore, catering to both industrial and commercial sectors throughout Pulau Ujong and the wider Southeast Asian region. Our Super Duplex round bars are designed to excel in tough environments, boasting remarkable strength, durability, and corrosion resistance. Crafted to meet international standards like ASTM A276 and ASTM A479, these bars are perfect for structural components, machined parts, and high-stress systems. With precise tolerances, a smooth surface finish, and consistent mechanical properties, Chuck Metals provides dependable solutions for marine, chemical, offshore, and energy applications.
Super Duplex Steel Round Bars are typically produced from high-performance grades such as UNS S32750, S32760, and Zeron 100. They generally contain around 25% chromium, 7% nickel, 3–4% molybdenum, and nitrogen, with optional additions of copper or tungsten. These bars deliver impressive tensile strength (750–930 MPa), yield strength (≥550 MPa), and high impact toughness. Their unique austenitic-ferritic structure offers excellent resistance to pitting, crevice corrosion, and chloride stress corrosion cracking, making them ideal for harsh environments like seawater, chemical processing, and high-pressure systems.

Yes, Super Duplex Steel Round Bars can withstand moderately high temperatures but are not ideal for prolonged use above 300°C, as this may reduce their corrosion resistance and mechanical properties.
Yes, Super Duplex Steel Round Bars are highly recyclable. Their materials, including chromium, nickel, and molybdenum, can be reused, promoting sustainability and reducing waste in industrial applications.
No, Super Duplex Steel Round Bars typically do not require additional corrosion protection coatings, as their high chromium, molybdenum, and nitrogen content provides excellent inherent corrosion resistance in harsh environments.
Super Duplex Steel Round Bars find extensive use in applications that demand both high mechanical strength and outstanding corrosion resistance. In the oil and gas sector, they are utilized for shafts, fasteners, valves, and subsea components that face extreme pressure and corrosive fluids. In marine settings, they are perfect for propeller shafts, rudder pins, and seawater piping. Chemical and petrochemical plants rely on them for process equipment, flanges, and fittings. These round bars are also employed in desalination systems, pulp and paper production, and power generation, where reliability, longevity, and resistance to harsh conditions are crucial.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
