What is AWS Class E309LMo-16 Coated Electrodes?

AWS E309LMo-16 coated electrodes are made from austenitic stainless steel and contain about 22–24% chromium, 12–14% nickel, and 2–3% molybdenum, all with low carbon content. This unique blend boosts their resistance to hot cracking, oxidation, and corrosion, particularly in harsh environments. The weld metal produced offers impressive tensile strength, great ductility, and reliable impact toughness. These electrodes ensure stable arc characteristics, easy slag removal, and consistent mechanical properties, even when faced with high dilution conditions.
