Chuck Metals is a reliable manufacturer and supplier of Duplex Steel Bright Bars in Singapore, providing precision-engineered stainless solutions to various industries across Pulau Ujong and Southeast Asia. These bright bars are celebrated for their high strength, excellent surface finish, and remarkable corrosion resistance, making them perfect for critical applications that demand both mechanical durability and aesthetic appeal. Adhering to ASTM A276, A479, and other international standards, our bright bars are crafted using advanced cold drawing or centerless grinding techniques to ensure superior dimensional accuracy and a smooth, shiny surface.
Typically, Duplex Steel Bright Bars consist of 22–25% chromium, 4.5–6.5% nickel, and 2.5–3.5% molybdenum, with added nitrogen to boost strength and pitting resistance. They boast a tensile strength ranging from 600 to 900 MPa and a yield strength of about 450 to 620 MPa, which is nearly double that of standard stainless steels. The duplex microstructure offers excellent resistance to stress corrosion cracking, erosion, and chloride-induced corrosion, while also providing high fatigue strength and good machinability.
