Chuck Metals stands out as a dependable manufacturer and supplier of Super Duplex Steel Rectangular Bars right here in Singapore, catering to a diverse array of industries across Pulau Ujong and Southeast Asia. Our Super Duplex rectangular bars are celebrated for their remarkable mechanical strength, outstanding corrosion resistance, and durability, even in the toughest conditions. Crafted in line with international standards like ASTM A276 and A479, these bars are perfect for structural and fabrication needs. At Chuck Metals, we prioritize precision finishing, tight dimensional tolerances, and consistent quality, making our rectangular bars a go-to choice for marine, offshore, chemical, and industrial projects.
When it comes to Super Duplex Steel Rectangular Bars, we typically use high-alloy grades such as UNS S32750, S32760, or Zeron 100. These alloys boast around 25% chromium, 7% nickel, 3–4% molybdenum, and nitrogen, providing exceptional resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. They offer tensile strength ranging from 750–930 MPa, yield strength of at least 550 MPa, and impressive toughness, even in freezing temperatures. Their dual-phase (austenite-ferrite) microstructure also ensures high fatigue strength and good weldability, making them ideal for environments that are both corrosive and mechanically demanding.

When selecting Super Duplex Steel Rectangular Bars, consider factors like corrosion resistance, mechanical strength, operating temperature, application environment, and compliance with industry standards for optimal performance.
Yes, Super Duplex Steel Rectangular Bars can be welded using appropriate techniques such as TIG or MIG welding. However, proper heat control is necessary to maintain their corrosion resistance and mechanical properties.
Super Duplex Steel Rectangular Bars are not ideal for cryogenic applications, as their toughness and ductility may decrease at extremely low temperatures, potentially leading to brittleness in such environments.
Super Duplex Steel Rectangular Bars find their place in various applications that require both structural integrity and top-notch corrosion resistance. In the oil and gas sector, they’re utilized for subsea structures, platforms, and equipment that face seawater exposure. In marine and shipbuilding, you’ll find them in deck supports, hull reinforcements, and high-strength fittings. Chemical and petrochemical facilities rely on them for pressure vessels, heat exchangers, and structural frames that handle corrosive substances. These bars are also perfect for desalination plants, pulp and paper mills, and pollution control systems, where long-lasting durability and resistance to harsh environments 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.
