Nakamura Stainless stands out as a top manufacturer and supplier in Pulau Ujong, Singapore, specializing in high-quality stainless steel welding consumables designed for peak performance. Their AWS Class ER309/309L MIG and TIG Filler Welding Wire and Rod are perfect for welding different metals and overlay applications where both corrosion and heat resistance are crucial. With a well-balanced mix of chromium and nickel, these products guarantee strong welds, stability, and resistance to oxidation. The low-carbon “L” variant helps reduce carbide precipitation, enhancing resistance to intergranular corrosion. These filler wires and rods are highly trusted for projects that face high temperatures and corrosive environments.
The AWS Class ER309/309L MIG and TIG Filler Welding Wire and Rod typically features 22–24% chromium and 12–14% nickel, along with manganese, silicon, and carefully controlled carbon levels. The elevated chromium and nickel content boosts both corrosion and oxidation resistance, even at temperatures reaching 1095°C. ER309 delivers robust mechanical properties, while ER309L, with its lower carbon content, provides better resistance to intergranular corrosion and cracking. The weld deposits showcase high tensile and yield strength, excellent ductility, and solid toughness, making them reliable for joining dissimilar steels, stainless overlays, and applications in high-temperature environments.
