S125644-035 - Hobart Hoballoy 9018-M 1/8" Stick Electrode 50lb Can

Hobart Hoballoy 9018-M Welding Electrode - 1/8" Diameter

The Hobart Hoballoy 9018-M is a high-efficiency, low-hydrogen stick electrode engineered for the welding of high-tensile steels and low-alloy materials. Conforming to AWS A5.5 E9018-M classification, this electrode is specifically formulated to produce welds with high tensile strength (minimum 90 ksi) and excellent notch toughness, even at lower temperatures. This 50lb can of 1/8" rods is an essential consumable for heavy industrial applications involving pressure vessels, military hardware, and structural components subject to high stress.

One of the defining characteristics of the Hoballoy 9018-M is its moisture-resistant coating. In critical welding applications, moisture absorption in the flux can lead to hydrogen cracking, a catastrophic failure mode in high-strength steels. Hobart's formulation minimizes this risk, meeting stringent moisture limits. The iron powder addition in the coating also assists in higher deposition rates compared to non-iron powder electrodes, improving productivity without sacrificing weld quality.

Operable on Direct Current Electrode Positive (DCEP), this electrode provides deep penetration and fusion. It is designed for joining steels such as T-1, HY-80, and HY-90, often found in earthmoving equipment, cranes, and shipbuilding. The slag system is designed to be easily detachable, revealing a clean, convex bead profile. For welders certified in critical code work, the consistency and reliability of Hobart Hoballoy 9018-M make it a trusted choice for meeting X-ray quality standards.
