When your job calls for welding chrome-moly pipe or boiler tubes, you need a rod that you can trust not to crack. The Hobart Hoballoy 8018-B2 is built for exactly that. This 1/8-inch stick electrode is the go-to choice for welders working on 1-1/4% Chrome, 1/2% Moly steels often found in power plants, refineries, and high-pressure steam lines. It delivers the high tensile strength (over 80,000 psi) required to match these heavy-duty base metals, ensuring your welds hold up under stress and high temperatures.
We know that moisture is the enemy of a good low-hydrogen weld. That's why Hobart formulated this rod with a special coating that resists moisture pick-up, even when you're working in hot, humid conditions. This resistance helps prevent hydrogen cracking—a welder's nightmare on critical joints—and helps you avoid that annoying porosity at the start of the bead. You get a clean, solid start every time, which means less grinding and fewer repairs. The slag lifts easily, and the bead profile is smooth, making your finish work much faster.
Versatility is key on the job site. The Hoballoy 8018-B2 runs smoothly on both AC and DCEP, so you can use it with whatever machine you have handy. It's an all-position rod, meaning you can tackle flat, horizontal, vertical, and overhead welds without changing consumables. Whether you are repairing a boiler tube in a tight spot or fabricating heavy-wall piping in the shop, this rod gives you the control and puddle visibility you need.
This product comes in a heavy-duty 50 lb can. The hermetic seal keeps the rods dry and ready to burn right out of the package. If you are doing code work or critical maintenance, don't take chances with inferior filler metals. Stick with Hobart Hoballoy 8018-B2 for consistent, high-quality results on your chrome-moly projects.
