The E309/309L‑16 electrode is tailored for shielded-metal-arc welding (SMAW) of austenitic stainless steels, and it’s also great for joining stainless steels to carbon or low-alloy steels. The typical composition of the deposited weld metal includes: Carbon ≤ 0.04 %, Chromium 22.0-25.0 %, Nickel 12.0-14.0 %, Manganese 0.5-2.5 %, Silicon ≤ 1.0 %, and Molybdenum ≤ 0.75 % (for 309/309L). As-welded mechanical properties usually achieve a minimum tensile strength of around 75 ksi (≈ 520 MPa) and an elongation of at least 30 % in the deposited weld metal. The low-carbon “L” version (309L) offers enhanced resistance to carbide precipitation and inter-granular corrosion.
