S540451-033 - Hardalloy 118 5/32" Manganese Build-Up Electrode

Tough Rods for Heavy Impact Repairs

When you are out in the field fixing a rock crusher or repairing a bucket tooth that’s seen better days, you need a rod that can take a beating. The Hobart Hardalloy® 118 is your go-to stick electrode for building up and joining manganese steel parts. This 5/32" rod isn't just for looks; it lays down a deposit that actually gets harder the more it gets hit. We call it "work-hardening," but you can just call it tough as nails. It’s designed to handle the massive shock and impact that would shatter lesser welds, making it perfect for the heavy equipment used in quarries and mines.

Welders will appreciate how smooth this rod runs. Whether you are burning it on DCEP or AC, the arc is stable and consistent, with low spatter to keep your workpiece clean. One of the biggest headaches with hardfacing rods can be the slag, but Hardalloy 118 features a slag system that pops off easily, saving you time with the chipping hammer. It’s great for single or multiple pass applications, allowing you to build up worn-down surfaces back to dimension before capping them with a final hardfacing layer if needed.

This 10 lb can is hermetically sealed, so your rods stay fresh and dry until you crack the lid. Use Hardalloy 118 on crusher jaws, railroad frogs, or impactor bars. It’s specifically formulated for austenitic manganese steel, so you know you are getting the right metallurgical match for the job. If you are planning to put a super-hard wear layer on top, use this rod first to create a solid, crack-resistant cushion underneath. It’s the professional choice for serious heavy-duty repairs.
