S125132-035 - Hobart E8018-C1 3/32" Low Alloy Stick Electrode (50lb Can)

Technical Overview: Hobart Hoballoy 8018-C1

The Hobart Hoballoy 8018-C1 is a high-quality, low-hydrogen stick electrode designed specifically for the Shielded Metal Arc Welding (SMAW) of high-strength, low-alloy steels. Classified under AWS A5.5 as E8018-C1, this electrode is formulated with a nominal 2% to 2.5% nickel content in the weld deposit. This metallurgical composition is critical for applications requiring superior notch toughness at sub-zero temperatures, typically down to -75°F (-60°C). It provides a minimum tensile strength of 80,000 psi, making it suitable for structural components that must withstand significant stress and cold weather conditions.

Engineered for versatility, the Hoballoy 8018-C1 operates effectively on both Direct Current Electrode Positive (DCEP) and Alternating Current (AC). The AC capability is particularly beneficial in preventing arc blow, a common issue when welding complex joint geometries or magnetized plates. The electrode features a moisture-resistant coating that helps maintain low hydrogen levels in the weld metal, significantly reducing the risk of hydrogen-induced cracking (cold cracking) in the heat-affected zone. This 3/32-inch diameter variant allows for precise control in thinner sections or root passes.

Packaged in a durable, hermetically sealed 50-pound can, these electrodes are protected from atmospheric moisture absorption prior to opening. For optimal performance and code compliance, it is recommended to store opened consumables in a rod oven according to manufacturer specifications. The Hoballoy 8018-C1 is the professional's choice for critical fabrication where metallurgical integrity and low-temperature impact properties are non-negotiable.
