Description
AR400 Abrasion-Resistant Steel Plate
AR400 is a medium-carbon, abrasion-resistant steel plate specifically designed for applications requiring high wear resistance combined with good formability and weldability. The “AR” in AR400 stands for “Abrasion Resistant,” and the “400” denotes its Brinell hardness rating (approximately 360–440 HBW), making it suitable for moderate to heavy wear applications.
Key Features
- High wear resistance
- Moderate impact resistance
- Tough under extreme load and friction
- Cost-effective solution for extending equipment life

Benefits
- Extended Service Life: Resists abrasion and impact, reducing downtime and replacement costs.
- Customizable: Can be cut using plasma, oxy-acetylene, laser, or water jet to meet specific project requirements.
- Cost-Effective: Offers a balance of performance and affordability compared to higher-grade AR steels like AR450 or AR500.
- Reliable Performance: Through-hardened for consistent hardness, unlike surface-hardened alternatives that wear quickly in the core.
Applications
AR400 steel plate excels in high-wear environments across various industries, including:
- Mining and Quarrying: Liners for chutes, hoppers, and dump truck beds.
- Construction: Components for bulldozers, excavators, and bucket liners.
- Material Handling: Conveyor liners, fan blades, and wear straps.
- Other Uses: Cement mixer drums, shooting range targets, and equipment housings.
