Hobart 418 E7018-1 H4R Carbon Steel Electrode Overview

The Hobart 418 is a premium quality, low hydrogen carbon steel electrode designed for critical welding applications requiring high mechanical properties and X-ray quality welds. Classified as E7018 H4R and E7018-1 H4R, this electrode is engineered to provide exceptional resistance to moisture absorption, minimizing the risk of hydrogen-induced cracking in heavy structural fabrications. The 5/32-inch diameter is well-suited for welding heavier plate thicknesses in single or multiple pass applications, offering a deposition rate that enhances productivity in industrial environments.

Ideally suited for industries such as petrochemical, power generation, and shipbuilding, the Hobart 418 delivers a tensile strength of 78,500 psi and a yield strength of 65,500 psi. It is formulated to weld effectively on low, medium, and high-carbon steels, as well as low-alloy structural steels. The electrode's formulation allows it to perform reliably even when the base metal surface is not perfectly clean, handling minor rust or dirt better than many standard low-hydrogen rods. This makes it a preferred choice for infrastructure repair and rebuilding projects that must adhere to strict State and Federal Transportation Codes.

Packaged in a 50 lb hermetically sealed can, the Hobart 418 ensures factory-fresh performance upon opening. The H4R designation signifies that the coating is resistant to moisture pickup, which is critical for maintaining the low hydrogen status of the weld deposit over time. This electrode operates smoothly on both DCEP and AC currents, providing flexibility for shops with varying power source capabilities. Whether used for boiler pressure vessels, mining equipment, or railcar construction, the Hobart 418 provides the structural integrity and code compliance required for heavy-duty engineering projects.
