S125432-035 - Hobart Hoballoy E8018-B2 Low Alloy Stick Electrode 3/32" 50lb Can

High-Performance Chrome-Moly Welding Electrode

The Hobart Hoballoy 8018-B2 is a premium low-alloy stick electrode designed specifically for the welding of 1-1/4% Chromium, 1/2% Molybdenum steels. Engineered to meet the rigorous demands of industrial fabrication and maintenance, this electrode delivers a weld deposit with tensile strengths exceeding 80,000 psi. It is the preferred choice for MRO professionals working on boilers, pressure vessels, and associated piping systems where high-temperature service and creep resistance are critical. The 3/32-inch diameter allows for precise control in various joint configurations, making it versatile for both root passes and fill passes in complex assemblies.

Advanced Moisture Resistance

One of the standout features of the Hoballoy 8018-B2 is its specially formulated coating. In industrial environments, humidity and heat can compromise standard low-hydrogen electrodes, leading to moisture absorption and subsequent hydrogen cracking in the weld zone. Hobart has engineered this coating to resist moisture pick-up significantly better than standard electrodes. This resistance to reabsorption aids in the elimination of starting porosity and ensures that the hydrogen content remains within safe limits, which is vital when welding high-strength, low-alloy steels that are susceptible to cracking.

Operational Efficiency and Versatility

This electrode is designed for all-position welding, providing flexibility for operators working in difficult field conditions. It operates smoothly on both Direct Current Electrode Positive (DCEP) and Alternating Current (AC), offering a stable arc and manageable puddle control. The slag system is designed for easy removal, reducing post-weld cleanup time and improving overall productivity. Whether used for single-pass or multiple-pass applications, the Hoballoy 8018-B2 produces X-ray quality welds that meet stringent code requirements.

Typical Applications

The Hoballoy 8018-B2 is extensively used in the power generation, petrochemical, and construction industries. It is specifically tailored for materials such as ASTM A387 Grade 11 plates and A335 Grade P11 pipes. By choosing this Hobart electrode, facilities managers and procurement specialists ensure they are stocking a consumable that provides reliability, safety, and compliance with AWS A5.5 specifications.
