AWS Class E320LR-16 Electrodes contain 18-20% chromium, 32-36% nickel, 2-3% molybdenum, and minor amounts of niobium and manganese, with iron as a balance. The “LR” grade indicates low residual elements, reducing the chance of hot cracking. They provide a tensile strength of around 550 MPa and elongation of 30-35%, along with excellent toughness even at high temperatures. The weld deposits resist severe chemical attack, including both oxidizing and reducing environments. Their combination of corrosion resistance, flexibility, and strength makes them ideal for making equipment exposed to extreme conditions.
