S125758-035 - Hobart Hoballoy E10018-D2 Low Alloy Stick Electrode 3/16"

High-Performance Manganese-Molybdenum Welding Electrodes

The Hobart Hoballoy 10018-D2 is a premium low-alloy steel electrode designed for the welding of high-tensile steels where weld metal strength must equal or exceed 100,000 psi. Engineered to meet the rigorous AWS A5.5 specifications, this E10018-D2 classified electrode features a specialized manganese-molybdenum alloy core and a low-hydrogen iron powder coating. This composition ensures exceptional mechanical properties, making it the preferred choice for industrial fabrication sectors requiring superior structural integrity and resistance to cold cracking.

Industrial procurement specialists will appreciate the consistent quality and traceability associated with the Hobart brand. The 3/16-inch diameter is optimized for heavy deposition rates in flat and horizontal positions, significantly improving productivity on thick-section materials. The electrode formulation provides a stable arc and excellent puddle control, resulting in X-ray quality welds essential for critical infrastructure projects. The inclusion of manganese and molybdenum enhances the weld deposit's hardenability and impact toughness, even at sub-zero temperatures, which is a critical requirement for pressure vessel and piping applications.

Moisture control is paramount in high-strength welding to prevent hydrogen-induced cracking (HIC). The Hoballoy 10018-D2 is packaged in a hermetically sealed 50-pound can, ensuring the coating remains dry and factory-fresh until the moment of use. This packaging solution reduces waste and the immediate need for re-baking upon opening, provided standard exposure limits are observed. For MRO operations dealing with earthmoving equipment, crane booms, or high-stress structural components, this electrode offers the reliability and mechanical performance necessary to meet stringent engineering codes.
