Abrasion-Resistant Steel Parts for
Hoppers, Chutes & Heavy Equipment
AR400 wear plate combines high hardness with practical fabrication routes for liners, guards, chute sections and high-wear machine parts that see sliding abrasion.
- Typical hardness: 360-440 HBW
- Cutting, drilling, countersinking and weld prep
- DFM support for wear direction and replaceable liners
Used for mining, agriculture, aggregate, recycling and material handling equipment
Material Overview
AR400 is an abrasion-resistant quenched and tempered steel plate commonly specified where sliding wear destroys mild steel too quickly. It is not a cosmetic sheet material; it is a heavy-duty choice for replaceable liners, chutes, hoppers, guards, bucket wear parts and conveyor handling components.
Compared with mild steel or standard carbon steel, AR400 gives much better abrasion life, but it needs more careful cutting, drilling, bending and welding planning.

Wear Plate Grade Comparison
AR400 sits in the practical middle: harder than common structural steels, easier to fabricate than very high hardness wear plate.
| Grade | Typical Hardness | Wear Resistance | Formability | Weldability | Typical Use |
|---|---|---|---|---|---|
| Mild Steel | 120-180 HBW | Low | Excellent | Excellent | General frames, covers, brackets |
| AR400 | 360-440 HBW | High | Moderate | Good with controls | Chutes, liners, hoppers, guards |
| AR500 | 470-540 HBW | Very high | Limited | More restrictive | Severe wear liners and impact plates |
Relative Wear Resistance
A practical comparison for material selection; exact life depends on abrasive type, speed, impact and part geometry.
