ED032600 - Lincoln Excalibur 8018-C3 1/8-Inch Stick Electrode (30lb Carton)

Industrial Grade Low Alloy Stick Electrode

The Lincoln Electric Excalibur® 8018-C3 MR® is a premium low alloy stick electrode designed specifically for applications requiring a 1% nickel deposit. Engineered to meet the rigorous demands of the oil and gas industry, this electrode is fully compliant with NACE MR0175 standards, making it an essential consumable for sour gas applications where resistance to sulfide stress cracking is paramount. The electrode carries the AWS classification E8018-C3 H4R, indicating its high tensile strength and low hydrogen content, which is critical for preventing hydrogen-induced cracking in high-stress structural welds.

One of the defining characteristics of the Excalibur line is its Moisture Resistant (MR) coating. This advanced coating technology significantly reduces the rate of moisture pickup, ensuring that the electrode maintains its low hydrogen status even in humid environments. This feature is particularly beneficial for field operations in cross-country pipeline construction and shipbuilding, where storage conditions may not always be optimal. The ED032600 SKU comes packaged in a 30 lb master carton containing three 10 lb Easy Open Cans, providing convenient handling and ensuring product freshness until the moment of use.

Beyond its chemical compliance, the Excalibur 8018-C3 delivers exceptional mechanical properties. The 1% nickel addition enhances the notch toughness of the weld metal, providing superior impact resistance at lower temperatures compared to standard carbon steel electrodes. This makes it a preferred choice for process piping and structural fabrication where ductility and durability are non-negotiable. Lincoln Electric also provides test data for SSC (NACE TM0177) and HIC (NACE TM0284), offering engineers and quality control managers the documentation needed to validate weld procedures in critical infrastructure projects.

The electrode is manufactured in the United States and is designed to operate with a smooth, stable arc that resists fingernailing. The square coating burn-off allows for precise control, enabling welders to produce high-quality, defect-free welds consistently. Whether used for root passes or fill and cap passes in heavy wall pipe, the Excalibur 8018-C3 stands as a benchmark for reliability in low alloy welding consumables.
