S125651-035 - Hobart E9018-M Low Alloy Stick Electrode 5/32" 50lb

Hobart Hoballoy 9018-M Stick Electrode Overview

The Hobart Hoballoy 9018-M is a premium quality, low hydrogen, iron powder electrode designed for the Shielded Metal Arc Welding (SMAW) process. Engineered to meet the AWS E9018-M classification, this electrode is specifically formulated for joining high-strength low-alloy (HSLA) steels where weld metal tensile strength in the 90,000 psi range is required. The 'M' designation indicates compliance with specific military requirements regarding moisture content and mechanical properties, making it a reliable choice for critical structural fabrication.

This 5/32-inch diameter electrode provides excellent deposition rates and arc stability. The iron powder coating assists in maintaining a smooth, consistent arc while enhancing metal recovery. One of the defining characteristics of the Hoballoy 9018-M is its superior impact toughness, particularly at lower temperatures, which is essential for equipment operating in harsh environments. The weld deposit is highly resistant to cracking, a common challenge when welding high-tensile steels.

Packaged in a 50 lb hermetically sealed can, the electrodes are protected from atmospheric moisture absorption, ensuring they remain within low-hydrogen limits until opened. This is crucial for preventing hydrogen-induced cracking in the heat-affected zone of the base metal. The electrode operates primarily on Direct Current Electrode Positive (DCEP), providing deep penetration and strong fusion. It is suitable for all-position welding, although the 5/32" size is most commonly used in flat and horizontal positions for heavy plate fabrication.

Industries utilizing the Hoballoy 9018-M include heavy construction, mining, shipbuilding, and pressure vessel manufacturing. It is an ideal consumable for welding T-1 steels, HY-80, and other quenched and tempered grades. Users can expect X-ray quality welds with easily removable slag and minimal spatter, reducing post-weld cleanup time and improving overall productivity.
