AWS Class E320LR-16 electrodes deposit a low-carbon, high-alloy austenitic stainless steel weld metal enriched with chromium, nickel, and molybdenum. The “LR” designation indicates low residual elements, improving resistance to hot cracking and enhancing weld ductility. The weld metal provides good tensile and yield strength, excellent toughness, and superior resistance to pitting and crevice corrosion. These electrodes operate smoothly on AC or DC current, with stable arc performance and easy slag removal.
