S125532-035 - Hobart Hoballoy E9018-B3 Low Alloy Stick Electrode 3/32" 50lb

Performance and Reliability for Chrome-Moly Welding

When your job calls for welding chrome-moly pipe or repairing high-pressure boilers, you need a rod that runs smooth and deposits sound metal every time. The Hobart Hoballoy 9018-B3 is built for the professional welder who demands consistency and quality in critical applications. This 3/32-inch stick electrode is your go-to solution for welding 2.25% Chromium / 1% Molybdenum steels, commonly found in power plants, refineries, and high-stress construction projects. With a 50lb can, you have the volume needed to tackle large pipe joints and extensive fabrication work without constant restocking.

One of the biggest headaches with low-alloy stick welding is fighting porosity and hydrogen cracking, especially in humid environments. Hobart has addressed this with a specially formulated moisture-resistant coating. This means the rod stays drier longer, giving you confidence that your starts will be solid and your welds will pass X-ray inspection. You will notice the difference in the arc stability; it is smooth and predictable, whether you are running DCEP or AC. This stability is crucial when you are welding out of position, allowing you to manipulate the puddle effectively in vertical-up or overhead welds without fighting the rod.

Cleanup is another area where the Hoballoy 9018-B3 shines. The slag system is designed to detach easily, often curling up on its own as the weld cools. This saves you valuable time on chipping and grinding, letting you move on to the next pass or the next joint faster. The bead profile is flat to slightly convex with fine ripples, producing a professional-looking finish that inspectors appreciate. Whether you are fabricating new pressure vessels or performing maintenance on steam lines, this electrode provides the high strength (90,000 psi tensile) and ductility required to ensure the safety and longevity of the weldment. It is a workhorse rod for the serious industrial welder.
