Ed Stainless offers AWS Class E309/309L-16 Electrodes, designed for joining stainless steel to carbon steel as well as for joining dissimilar stainless steels. These electrodes provide superior corrosion and oxidation resistance and thus are ideally used in high-temperature and extreme-environmental applications. The E309/309L-16 electrodes are well suited to petrochemical, power generation, and food processing industries where durability and corrosion resistance are the priority. They provide consistent arcs, less spatter, and sound welds, ensuring stable joints in a variety of industrial and manufacturing processes.
AWS Class E309/309L-16 Electrodes have 22-25% Chromium and 12-15% Nickel content, providing superior oxidation, corrosion, and high-temperature degradation resistance. The “L” grade low carbon content reduces carbide precipitation, resulting in the stability of the weld for a long time. Tensile strength ranges from 550 to 750 MPa, while yield strength is approximately 210 MPa. These electrodes offer better arc stability, low spatter, and simple slag removal, making them suitable for applications where dependable, high-strength welds are needed to endure aggressive environments and high temperatures.
