Wear Plate
Wear plates are essential in extending the service life of equipment and reducing maintenance costs. Whether it’s through quenched and tempered steels or advanced overlay technologies, selecting the right wear plate material depends on operating temperature, impact load, and abrasion type.
- Description
Wear plate refers to a type of steel plate designed to resist abrasion, impact, and erosion in demanding working environments. It is widely used in industries such as mining, construction, cement, and steel production. The choice of wear plate material depends on the type of wear — sliding, impact, or high-temperature abrasion. Below are the most common types of wear-resistant steels used today:
| Type of Wear Plate | Material Description | Key Features | Typical Applications |
|---|---|---|---|
| AR400 / AR450 / AR500 Plate | Quenched and tempered alloy steel with high hardness and good toughness. | High abrasion resistance with moderate weldability. | Buckets, dump truck liners, crushers, and blades. |
| Chromium Carbide Overlay (CCO) Plate | Steel base with welded chromium carbide overlay layer. | Excellent wear resistance under sliding and moderate impact conditions. | Hoppers, chutes, conveyors, and coal handling systems. |
| Tungsten Carbide Overlay Plate | Base steel with tungsten carbide particles fused by welding or thermal spray. | Extreme hardness for severe abrasion and high-temperature service. | Mining, drilling, and earth-moving machinery. |
| Hardox / NM Series Plate | Swedish or Chinese-made wear-resistant steel with consistent hardness and formability. | High toughness and good machinability. | Structural wear parts, construction equipment, and trailers. |
| Boron Alloyed Steel Plate | Steel with added boron for improved hardenability and wear resistance. | Cost-effective for moderate wear environments. | Agricultural tools, plows, and wear bars. |
