OVERVIEW

Armor Your Equipment Against Wear

When your bucket teeth, crusher rolls, or screw conveyors are wearing down too fast, reach for Hobart Hardalloy 148. This 3/16" hardfacing rod is the heavy-hitter you need for severe abrasion. It lays down a super-hard layer of chromium carbide that acts like armor plating for your steel. Whether you are patching up an excavator bucket in the field or resurfacing a Muller tire in the shop, this rod runs smoothly on both AC and DC+ welders, giving you flexibility regardless of your power source.

Welders appreciate the Hardalloy 148 for its user-friendly arc and easy slag release, which speeds up the job when you have a lot of surface area to cover. The bead appearance is excellent, and while it will show relief cracks (cross-checking) as it cools, don't worry—that's exactly what it's supposed to do to relieve stress without popping off. Just remember, this stuff is hard! You won't be able to drill or machine it after welding; if you need to shape it, you'll have to grind it.

Best Uses

  • Earthmoving: Bucket lips, teeth, and sides.
  • Mining: Crusher rolls, hammers, and chutes.
  • Agriculture: Plow shares and tillage tools.
  • General: Pump shells and sand chutes.

Get the job done right and keep your equipment running longer with the reliable performance of Hobart hardfacing.

FAQ

The Hobart Hardalloy 148 typically produces a hardness of Rockwell C 55-60, depending on base metal dilution and the number of layers applied.

No, the deposit is extremely hard and non-machinable. It can only be finished by grinding.

This electrode can be run on both AC (Alternating Current) and DCEP (Direct Current Electrode Positive).

Yes, this electrode is designed to 'cross-check' or form relief cracks. This relieves residual stress in the hard deposit and helps prevent the coating from spalling or peeling off.

It is generally recommended to limit buildup to 2 or 3 layers. Excessive layers of high chromium carbide can lead to spalling due to high internal stresses.

For the 3/16" diameter rod, a range of approximately 150 to 220 Amps is typically recommended.

It offers moderate impact resistance but is primarily designed for severe abrasion. For high impact applications (like rock crushing impactors), a manganese steel electrode might be more appropriate.

Preheat depends on the base metal's carbon content and thickness. High carbon or alloy steels usually require preheat to prevent underbead cracking, though the hardfacing layer itself will check.
