S125551-035 - Hobart Hoballoy 9018-B3 Stick Electrode 5/32" (50lb Can)

Hobart Hoballoy 9018-B3: The Professional's Choice for Chrome-Moly Steel

When your welding project involves 2.25% Chromium and 1% Molybdenum steels, you need a filler metal that matches the base material's performance characteristics perfectly. The Hobart Hoballoy 9018-B3 (5/32" diameter) is the premier solution for these demanding alloys. Packaged in a robust 50lb can, these stick electrodes are formulated to provide X-ray quality welds with exceptional mechanical properties, specifically tailored for service in high-temperature environments found in refineries and power plants.

The "B3" designation in the AWS E9018-B3 classification indicates the specific chemical composition designed to resist creep and maintain high tensile strength at elevated service temperatures. This makes the Hoballoy 9018-B3 indispensable for welding steam pipes, boilers, and hydrocrackers. Welders will appreciate the smooth running characteristics of this rod. It operates well on both AC and DCEP (Direct Current Electrode Positive), providing flexibility depending on your power source and specific joint configuration. The arc is stable with minimal spatter, allowing for precise control over the weld puddle, which is crucial when welding out-of-position on fixed pipework.

One of the standout features of this electrode is its moisture-resistant coating. In critical code work, hydrogen cracking is a major concern. Hobart's advanced coating technology minimizes moisture absorption, thereby keeping diffusible hydrogen levels low. This significantly reduces the risk of cold cracking, ensuring the structural integrity of the weldment. The 5/32" diameter is excellent for filling and capping passes on thicker wall pipes and plates, offering a good balance between deposition rate and heat input control.

Key Performance Characteristics:

• High Tensile Strength: Delivers a minimum tensile strength of 90,000 psi after stress relieving.
• Easy Slag Release: Saves time on chipping and grinding between passes.
• Consistent Chemistry: Ensures predictable response to post-weld heat treatment (PWHT).

For welders who refuse to compromise on quality, Hobart Hoballoy 9018-B3 provides the assurance that every bead laid will stand up to the rigors of industrial service. Ensure your shop is stocked with this essential chrome-moly filler metal.
