S540481-031 - Hobart Hardalloy 118 1/4" Hardfacing Electrodes (50lb Carton)

Armor Your Equipment with Hardalloy 118

When the job calls for serious armor against dirt, rock, and sand, reach for Hobart Hardalloy 118. This 1/4" stick electrode is a beast for laying down high-chromium carbide protection on parts that take a beating. If you are rebuilding crusher rolls or facing off dredge pumps, this rod gives you the abrasion resistance you need to keep equipment running longer. It hits a hardness of 55-60 HRC right out of the gate, making it one of the go-to choices for severe wear environments.

The Hardalloy 118 runs smooth on both AC and DCEP. If you're running a big buzz box or a generator in the field, this rod performs. The 1/4" diameter is perfect for filling up large areas fast, dumping plenty of metal with good bead contour. You'll notice the bead cross-checks (cracks) as it cools—don't sweat it. That's exactly what it's supposed to do. Those relief checks stop the hardfacing from popping off the base metal under stress. Just remember, this stuff is hard. You can't machine it; you have to grind it if you need to shape it.

Best practice? Limit your buildup to two or three layers to avoid spalling. If you need to build up more dimension, use a tough buffer layer first, then cap it with Hardalloy 118. It bonds well to carbon steel and austenitic manganese steel, making it a versatile tool in your hardfacing arsenal. Grab a 50lb carton and keep your heavy iron in the dirt where it belongs, not in the repair shop.
