AR400 Wear Resistant Steel Plate

Overview of AR400 Wear Resistant Steel Plate

AR400 is a premier, through-hardened abrasion-resistant alloy steel plate engineered to provide superior protection against wear in high-friction environments. The “AR” stands for “Abrasion Resistant,” and “400” represents its nominal Brinell hardness value of 400 HBW. AR400 is the most widely utilized grade in the wear-resistant series due to its exceptional balance of high surface hardness, structural toughness, and excellent fabrication characteristics. It is specifically designed for industrial components that must withstand constant sliding abrasion and moderate impact energy.

Shandong Tanglu Metal Material Co., Ltd. supplies high-quality AR400 plates processed through a precision Quenching and Tempering (Q+T) heat treatment. This process ensures a uniform martensitic microstructure, providing consistent wear resistance from the surface deep into the core of the material. For B2B buyers in the mining, aggregate, and heavy construction sectors, AR400 represents a cost-effective solution that significantly extends the lifespan of equipment while remaining highly versatile for various manufacturing processes.

Key Features and Engineering Advantages

The defining feature of AR400 is its hardness range, typically maintained between 360 and 440 HBW. This hardness level makes the steel approximately four times more durable than standard structural carbon steel, significantly reducing equipment downtime and replacement costs. One of the greatest engineering advantages of AR400 is its remarkable formability and weldability. Unlike higher-hardness grades, AR400 can be successfully cold-bent and welded with standard industrial equipment, provided that proper low-hydrogen consumables and preheating procedures are followed.

AR400’s chemical composition is optimized with moderate carbon levels and alloying elements like Manganese and Chromium to ensure high hardenability and impact resistance. Every AR400 plate delivered by Tanglu is accompanied by original Mill Test Certificates (MTC) documenting its chemical and mechanical compliance. This level of material traceability ensures that your projects meet the rigorous safety and durability standards required in extreme industrial material-handling applications.

Main Applications of AR400 Steel Plate

AR400 is the industry workhorse for wear protection across multiple heavy sectors. It is primarily used for the construction of conveyor liners, heavy-duty chutes, and material-handling hoppers in the mining and quarrying industries. In the construction and earthmoving sectors, it is an essential material for fabricating excavator bucket liners, cutting edges, and wear strips for dump truck bodies.

Beyond mining and construction, AR400 is extensively utilized in the cement processing and recycling industries for mixing blades, screening equipment, and waste-handling liners exposed to continuous friction. It is also a preferred choice for the agricultural sector in high-wear components such as grain chutes and tillage equipment. Due to its proven durability and ease of fabrication, AR400 remains the global benchmark for 400 Brinell abrasion-resistant steel plates.
