What is AWS Class E320LR-16 Coated Electrodes?

The AWS Class E320LR-16 Coated Electrodes mainly consist of 19–21% chromium, 32–36% nickel, and 2–3% molybdenum, along with low levels of residual elements like carbon and silicon. This low carbon “LR” formulation helps minimize the risk of intergranular corrosion while boosting the toughness of the weld metal. The weld deposit creates a stable austenitic structure, which provides excellent resistance to hot cracking and stress corrosion. Mechanical properties include a tensile strength of about 550–600 MPa, along with good elongation and impact resistance. E320LR-16 electrodes perform reliably with both AC and DC+ current, ensuring consistent results across all welding positions.

AWS Class E320LR-16 Coated Electrodes Uses

These AWS Class E320LR-16 Coated Electrodes are commonly used in industries such as chemical processing, pharmaceuticals, pulp and paper, and power generation, where resistance to acids, chlorides, and other corrosive agents is crucial. They are particularly suited for welding alloys like UNS S32003 and similar materials found in reactors, heat exchangers, pumps, and piping systems. The low carbon content enhances the toughness of the weld metal, making them ideal for fabricating or repairing equipment that endures thermal cycling and stress. E320LR-16 electrodes provide strong, durable welds for essential operations in aggressive chemical and high-temperature environments.
