The AWS Class ER320LR MIG and TIG fillers are low-alloy steel consumables primarily made of iron, with carefully controlled amounts of manganese, chromium, molybdenum, and nickel to boost strength, toughness, and resistance to thermal and mechanical stresses. The LR designation signifies a low-hydrogen, rutile-type wire/rod that’s ideal for critical welds, minimizing the risk of cracking. In terms of mechanics, the weld metal from ER320LR filler typically delivers high tensile strength (often around 80–90 ksi / 550–620 MPa) along with good elongation and impact resistance, ensuring it performs well even under tough conditions.
