ED032878 - Lincoln Excalibur 8018-B2 3/32" Stick Electrode (24lb Carton)

Lincoln Electric Excalibur 8018-B2 Stick Electrode

The Lincoln Electric Excalibur 8018-B2 is a premium low alloy stick electrode engineered for critical welding applications involving 1.25% chromium and 0.50% molybdenum steel. This electrode is a staple in industries requiring high-integrity welds capable of withstanding elevated temperatures and pressures, such as power generation, petroleum processing, and process piping. The ED032878 SKU represents a 24 lb Master Carton, typically containing three 8 lb cans, ensuring a substantial supply for project-based requirements.

One of the defining characteristics of the Excalibur line is its Moisture Resistant (MR) coating. This feature is crucial for maintaining low hydrogen levels (H4R designation) in the weld deposit, thereby significantly reducing the risk of hydrogen-induced cracking and porosity. The electrode is manufactured to meet strict AWS A5.5 and ASME SFA-A5.5 standards, providing certified performance for code-quality work. Its formulation ensures a consistent chemical composition, which is vital for matching the mechanical properties of chrome-moly base materials.

Operational efficiency is enhanced through the electrode's superior arc characteristics. It provides a stable, easy-to-control arc that is forgiving in various positions, although it excels in flat and horizontal applications. The slag system is designed for easy removal, often peeling away with minimal effort, which reduces post-weld cleaning time and improves overall productivity. For industrial MRO and fabrication shops dealing with alloy steels, the Excalibur 8018-B2 offers the reliability and performance necessary for high-stakes welding environments.
