S125158-035 - Hobart Hoballoy 8018-C1 Low Alloy Stick Electrode 3/16" 50lb Can

Hobart Hoballoy 8018-C1 Stick Electrode Overview

The Hobart Hoballoy 8018-C1 is a premium quality, low-alloy stick electrode designed specifically for applications requiring high tensile strength and exceptional notch toughness at sub-zero temperatures. Classified under AWS E8018-C1, this electrode features a nominal 2.5% nickel content in the weld deposit, which is the key factor in maintaining ductility and impact resistance in environments as cold as -75°F (-59°C). This makes it an indispensable consumable for industries dealing with cryogenic storage, heavy shipbuilding, and structural fabrication in arctic climates.

Engineered with a moisture-resistant, low-hydrogen iron powder coating, the Hoballoy 8018-C1 delivers X-ray quality welds with minimal risk of hydrogen-induced cracking. The iron powder addition not only stabilizes the arc but also enhances the deposition rate, allowing for faster travel speeds and improved productivity compared to standard low-hydrogen electrodes. The 3/16-inch diameter is particularly well-suited for filling larger joints and heavy-plate welding where heat input control and deposition efficiency are paramount.

This electrode operates effectively on both Direct Current Electrode Positive (DCEP) and Alternating Current (AC), providing versatility for various power sources. It is an all-position electrode, although the 3/16" size is most commonly used in flat and horizontal positions due to the larger weld pool. The slag system is designed for easy removal, leaving a clean, smooth bead profile that requires minimal post-weld cleanup. Packaged in a hermetically sealed 50lb can, the electrodes are protected from atmospheric moisture, ensuring they are ready for critical code work right out of the container.

Key Industrial Applications

The Hoballoy 8018-C1 is the electrode of choice for fabricating nickel-bearing steels and other low-alloy high-strength steels. It is extensively used in the construction of refrigerated ammonia tanks, liquefied gas storage vessels, and offshore structures exposed to severe cold. Additionally, it is compatible with weathering steels, providing a color match and corrosion resistance profile similar to the base material after exposure.
