Chuck Metals stands out as a top manufacturer and supplier of Super Duplex Steel Bright Bars in Singapore, catering to industrial clients not just in Pulau Ujong but throughout the Southeast Asian region. Our Super Duplex bright bars are meticulously precision-drawn and cold-finished, ensuring they boast superior dimensional accuracy, a fantastic surface finish, and tight tolerances. Renowned for their remarkable strength and resistance to corrosion, these bars are perfect for use in marine, offshore, chemical, and oil & gas industries. At Chuck Metals, we guarantee that all our bright bars comply with international standards like ASTM A276/A479, delivering reliable performance, exceptional durability, and consistent quality for critical structural and machining applications.
Typically, Super Duplex Steel Bright Bars are crafted from grades such as UNS S32750, S32760, and Zeron 100, featuring a composition of around 25% chromium, about 7% nickel, 3–4% molybdenum, and nitrogen, with some variants including elements like tungsten or copper. These bright bars provide impressive tensile strength (ranging from 750 to 930 MPa), yield strength of approximately 550 MPa or more, and high impact toughness, even in sub-zero temperatures. Their cold-drawn, polished surface not only enhances dimensional stability and finish quality but also offers superior resistance to pitting, crevice corrosion, and stress corrosion cracking in chloride and acidic environments.

The hardness of Super Duplex Steel Bright Bars typically ranges between 250-300 HB (Hardness Brinell), depending on the specific grade and heat treatment, offering excellent strength and resistance to wear and corrosion.
Yes, Super Duplex Steel Bright Bars can be recycled after use. Their high chromium and nickel content makes them highly recyclable, contributing to sustainability and reducing the need for new raw materials.
Super Duplex Steel Bright Bars are highly resistant to corrosion due to their high chromium and molybdenum content. However, in highly aggressive environments, additional coatings may be applied for extra protection.
uper Duplex Steel Bright Bars find their place in industries where high strength, precise dimensional tolerance, and corrosion resistance are essential. In the marine and offshore sectors, they are utilized for shafts, fasteners, and precision components that come into contact with seawater. The oil and gas industries rely on them for valves, pumps, and subsea equipment that operate under high pressure and corrosive conditions. In chemical and petrochemical plants, they serve in reactor components and structural supports. Their attractive finish and ease of machining also make them ideal for automotive, aerospace, and architectural applications where both performance and aesthetics are key.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
