Wear is an everyday reality in heavy-duty operations. From cement plants to mines, quarries, earthmoving sites and recycling facilities, augers, buckets, screws and chutes are constantly exposed to abrasion. If left unprotected, parts wear quickly, maintenance increases and downtime follows.
Hardfacing remains one of the most reliable ways to extend the life of parts. By applying a wear resistant layer only where it is needed, you protect the areas that take the most punishment without replacing the whole component. It is a proven approach used across workshops and site repairs.
The go-to wire for everyday hardfacing
For performance you can count on across a wide range of hardfacing jobs, HARDFACE HC-O is a great choice. Its self-shielded, metal-cored design removes the need for external gas, which suits site work and outdoor repairs. It works just as well in the workshop with suitable ventilation and fume extraction. Preparation is quick, so repairs can get underway without delay.
The metal-cored wire gives operators smooth, predictable welding performance. The arc is stable and easy to control, spatter is low and the bead profile is clean and consistent. Feeding is steady and deposition rates are high, helping operators work efficiently and keep good control of the application. With the right parameters, for example using a short circuit arc, HARDFACE HC-O can also be welded in the horizontal position with good control.
Wear resistance comes from chromium carbides that form in the overlay, providing strong abrasion resistance in mineral wear conditions.
In day-to-day use, HARDFACE HC-O is commonly applied to augers and screw flights, bucket lips and protection plates, ground engaging tools, conveyor components and other high-wear areas. When these parts fail, production stops. That is why an easy-to-use hardfacing wire that performs consistently matters.
When wear is more aggressive
Not every wear situation is the same. In harsher conditions, a more specialised wire often separates routine rebuilds from repeat failures. Welding Alloys manufactures its own cored wires and controls the chemistry, which means we can match the wire to the wear mechanism rather than offering only standard options.
For severe abrasion, HARDFACE HCNB-O includes a niobium addition that improves the formation of hard phases and increases resistance, while helping reduce cracking. For fine mineral abrasion in low impact conditions, HARDFACE HCB05-O uses a boron addition to increase hardness and extend service life.
These tailored options allow us to fine-tune performance to the operating environment and help customers get the maximum life from their parts.
Whether you use HARDFACE HC-O or a more tailored wire, the result is the same: longer service life, fewer maintenance interventions and reduced total costs.
