$144.00/10 lb ctnThe McKay E8018-B2 Stick Electrode is a premium low-alloy steel consumable designed specifically for the welding of 1-1/4% Chromium, 1/2% Molybdenum steels. Engineered to meet stringent AWS A5.5 specifications, this electrode provides exceptional mechanical properties, particularly in high-temperature service environments where creep resistance is paramount. It is the preferred choice for fabrication and repair in the power generation, petrochemical, and refinery industries, ensuring structural integrity in boilers, pressure vessels, and high-pressure piping systems.
This 3/32-inch diameter electrode features a specially formulated low-hydrogen iron powder coating that enhances deposition rates while minimizing the risk of hydrogen-induced cracking—a critical factor when welding hardenable low-alloy steels. The chemical composition is tightly controlled to match the base material properties of ASTM A387 Grade 11 plates and A335 Grade P11 pipes, ensuring consistent thermal expansion and corrosion resistance across the weld zone. The electrode operates effectively on both DCEP and AC currents, providing flexibility for various shop and field power sources.
For procurement specialists and QA/QC managers, the McKay E8018-B2 offers reliability and compliance. The manufacturing process adheres to rigorous quality control standards, delivering electrodes that consistently produce X-ray quality welds. The moisture-resistant coating reduces the frequency of re-drying cycles when handled correctly, optimizing workflow efficiency. Whether used for root passes in heavy wall pipe or fill and cap passes in pressure vessel seams, this electrode delivers the metallurgical performance required for code-compliant fabrication.
