| ER3 0 9L welding wire is primarily composed of austenitic stainless steel, containing approximately 2 3-2 5% chromium and 1 2-1 4% nickel. Designed for welding dissimilar metals, particularly for joining austenitic stainless steels to carbon and low-alloy steels A lower carbon content compared to standard ER3 0 9 electrodes. The low carbon content helps minimize the risk of sensitization and intergranular corrosion in the weld joint. Clean and aesthetically pleasing welds. It offers good wetting and flow characteristics, resulting in visually appealing weld bead Excellent corrosion resistance, suitable for applications where the welds need to maintain their corrosion-resistant properties. It is commonly used for welding stainless steel to carbon steel in applications exposed to corrosive environments. It is commonly used in industries such as petrochemical, power generation, and food processing. Shielding gas for MIG: 9 8%Ar+CO2 , for TIG: 1 0 0%Ar |
| MIG: 0. 8 to 1. 6 （mm) e.g. 0. 0 3 0″, 0. 0 3 5″, 0. 0 4 5″, 1 / 1 6″ TIG: 1. 0 to 5. 0 (mm) e.g. 3 / 6 4″, 1/ 1 6″, 3/ 3 2″, 1/ 8″, 5/ 3 2″, 3/ 1 6″ |
