Chuck Metals stands out as a trusted manufacturer and supplier of Duplex Steel Round Bars in Singapore, meeting the industrial needs of Pulau Ujong with precision-engineered, corrosion-resistant solutions. These round bars are celebrated for their remarkable strength, outstanding corrosion resistance, and impressive toughness, particularly in challenging environments. Crafted to comply with global standards like ASTM A276, ASTM A479, and ASME SA276, our duplex steel round bars are perfect for both structural and machining applications.
Made up of roughly 22–25% chromium, 4.5–6.5% nickel, 2.5–3.5% molybdenum, and nitrogen, these bars boast tensile strengths between 620 and 900 MPa and yield strengths from 450 to 620 MPa. The unique ferritic-austenitic dual-phase microstructure significantly boosts resistance to stress corrosion cracking, pitting, crevice corrosion, and fatigue, even in chloride-rich or acidic environments, all while ensuring good weldability and machinability.
