The AWS Class E309/309L‑16 electrodes are a type of austenitic stainless steel stick welding rods specifically crafted for welding stainless steels that belong to the 22% chromium and 12% nickel family. They’re also great for joining dissimilar metals, like stainless steel to carbon or low-alloy steels. The “L” version stands out with its extra-low carbon content (≤ 0.04%), which helps minimize carbide precipitation and enhances resistance to intergranular corrosion.
