What are Hardfacing Products? A Guide to Wear Plates, Wires, and More for Industrial Repair

From construction sites to mining pits and production plants, machinery is exposed daily to abrasion, impact, and demanding workloads. Over time, this wear leads to breakdowns, costly repairs, and production downtime. Hardfacing is a proven solution to extend equipment life and reduce these risks. It involves applying a tough, wear-resistant layer to surfaces that are most exposed to damage. This can be done through welding, bonding, or using pre-fabricated components.

Whether it’s a digger bucket, conveyor screw, or crusher blade, the right hardfacing products protect valuable assets and help businesses maintain efficiency. In this guide, we’ll explore the most common hardfacing products, from wear plates and carbide plates to hardfacing wire, chocky bars, and wear buttons, and how they solve everyday industrial wear problems.

The Hardfacing Arsenal: Types of Products & Their Specific Roles

Hardfacing Wires

Hardfacing wire is used in welding processes to rebuild worn surfaces or provide a protective coating. These wires come in different formulations depending on the environment,  from high-impact to high-temperature applications. By applying hardfacing wire through methods like MIG or submerged arc welding, equipment parts can be restored instead of replaced, cutting costs and extending service life.

Wear Plates (Carbide Plates)

Wear plates are pre-manufactured steel plates with a hardened surface layer. They are designed to handle sliding abrasion and impact in harsh conditions. In many industries, carbide plates are used as liners in hoppers, chutes, or buckets where material movement quickly wears down ordinary steel. These plates can be cut and shaped to fit specific equipment, offering a ready-to-install solution that delivers long-term protection.

Chocky Bars & Wear Buttons

Chocky bars and wear buttons provide spot protection in areas where full wear plates are not practical. Chocky bars are rectangular blocks bonded to a backing plate, while wear buttons are round inserts used for smaller or curved surfaces. Both are made from highly wear-resistant alloys and are easy to weld onto equipment. 

They are commonly used in excavator buckets, crushers, and heavy earthmoving machinery. By targeting the most vulnerable points, these components significantly reduce repair frequency.

The Problem Solver: Key Applications for Hardfacing Products

Hardfacing solutions can be applied across a wide range of industries. In construction, wear plates line the buckets of excavators and loaders to handle abrasive soil and rock. In mining, carbide plates and chocky bars protect crushers, conveyor systems, and drilling tools from constant impact.

In manufacturing, hardfacing wire is used to rebuild worn rollers, mixers, and hoppers. Even the energy sector benefits, as pumps and turbines can be reinforced against erosion. These applications highlight how hardfacing is not just about repair but also about preventing problems before they disrupt operations.

Benefits of a Proactive Hardfacing and Wear Protection Strategy

Waiting for equipment to fail before acting often leads to high costs and long delays. A proactive approach using wear plates, chocky bars, and other solutions reduces unplanned downtime. Businesses that plan regular maintenance with hardfacing enjoy longer equipment life, fewer replacements, and lower overall maintenance budgets. 

There are also safety benefits: well-maintained machinery is less likely to fail unexpectedly, reducing risks for operators. For industries under pressure to maintain productivity while managing costs, proactive wear protection is both a financial and operational advantage.

Choosing the Right Product for Your Wear Problem

Not all wear is the same. Some equipment suffers from sliding abrasion, while others face repeated heavy impacts. Selecting the right solution requires understanding the type of wear, the operating environment, and the equipment design. 

Carbide plates may be the best option for extreme abrasion, while hardfacing wire is ideal for rebuilding worn components. Chocky bars and wear buttons are excellent for spot reinforcement. Working with a knowledgeable supplier ensures the correct match, saving money and preventing ineffective repairs.

Frequently Asked Questions (FAQs)

1. What’s the difference between carbide plates and wear plates?Carbide plates are a type of wear plate with an especially tough surface, designed for extreme abrasion. Wear plates are the broader category.

2. How do I choose between chocky bars and wear buttons?Chocky bars suit larger flat surfaces, while wear buttons are ideal for smaller areas or curved surfaces where full plates can’t fit.

3. What hardfacing wire is best for my application?It depends on the type of wear. Different wires are designed for abrasion, impact, or high heat. A supplier can recommend the best match.

4. How long do hardfacing products typically last?The lifespan varies by material and application, but in general, they extend service life several times longer than untreated steel.

5. Can hardfacing products be applied to existing equipment?Yes. Hardfacing can rebuild worn areas or add extra protection to current equipment. This avoids costly full replacements.

6. What’s the ROI of investing in wear protection?Although the upfront cost is higher, reduced downtime, lower maintenance bills, and longer equipment life deliver strong returns over time.
