S126058-035 - Hobart Hoballoy 11018-M 3/16" Stick Electrodes (50lb Can)

Technical Overview of Hobart Hoballoy 11018-M

The Hobart Hoballoy 11018-M is a premium low-alloy steel stick electrode designed specifically for applications requiring exceptionally high tensile strength and toughness. Classified under AWS E11018-M, this electrode is engineered to produce weld deposits with a minimum tensile strength of 100,000 psi (often exceeding 110,000 psi in standard testing conditions). It is the consumable of choice for fabricating high-yield steels such as HY-80, HY-90, HY-100, and T-1 (ASTM A514) grades, which are commonly found in military, offshore, and heavy industrial environments.

This 3/16-inch diameter 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 thick sections and restrained joints. The coating formulation also includes iron powder, which improves deposition efficiency and assists in maintaining a stable arc. The electrode operates effectively on both Direct Current Electrode Positive (DCEP) and Alternating Current (AC), providing flexibility for various power source configurations. The slag system is designed for easy removal, and the puddle fluidity allows for excellent wetting action and tie-in at the toes of the weld, minimizing stress concentrations.

Metallurgically, the Hoballoy 11018-M deposit is a low-alloy composition typically containing manganese, nickel, and molybdenum to achieve its high strength and impact toughness properties, even at lower temperatures. It is suitable for single and multiple pass welding. Due to its low hydrogen nature, proper storage and handling are critical; the product is supplied in a hermetically sealed 50lb can to ensure factory-fresh performance upon opening. For critical code work, reconditioning in a rod oven may be required if the electrodes are exposed to the atmosphere for extended periods.
