Nakamura Stainless, a trusted supplier in Pulau Ujong, Singapore, offers AWS Class ER309/309L SAW and FLUX wires for welding dissimilar steels and cladding applications. The low carbon “L” grade improves resistance to intergranular corrosion, ensuring durability in corrosive settings. These wires provide smooth arc characteristics, high deposition rates, and consistent weld bead quality, making them efficient for submerged arc welding jobs. Nakamura Stainless guarantees each wire meets global quality standards, making them suitable for industries such as chemical processing, shipbuilding, and petrochemicals, where strength and corrosion resistance are essential.
AWS Class ER309/309L SAW and FLUX wires are made of 22–24% chromium and 12–14% nickel, with low carbon content (≤0.04% for “L”). This combination gives excellent oxidation and corrosion resistance while reducing the risk of carbide precipitation. Weld deposits typically show tensile strength around 600 MPa and elongation of 30–35%. These wires also display great toughness and mechanical stability, especially under high thermal cycling conditions. They are designed for joining dissimilar steels, buffer layers, and cladding, ensuring long-term reliability and durability in challenging industrial settings.
