The AWS Class ER320LR MIG and TIG filler wire primarily consists of chromium, nickel, molybdenum, and low carbon, with niobium added to boost corrosion and oxidation resistance. The low carbon content helps reduce carbide precipitation, which in turn provides excellent resistance to intergranular corrosion. Typical mechanical properties include a tensile strength of around 550 MPa, along with good ductility and toughness, even at higher temperatures. This filler guarantees strong, crack-resistant welds and exceptional performance in environments that contain acids, alkalis, and chlorides, ensuring durability under fluctuating heating and cooling conditions.
