ABRASION RESISTANT STEEL | WEAR RESISTANT STEEL
Hard. Tough. Long-lasting. Abrasion-Resistant.
Introduction to Abrasion Resistant Steel
Abrasion resistant steel, often abbreviated as AR steel and also known as wear-resistant steel, is a high-carbon alloy steel designed to provide exceptional hardness and toughness. With a composition that includes elements such as carbon and alloying materials, this type of steel undergoes a heat treatment process that enhances its wear resistance, making it highly suitable for applications involving high wear and tear. The hardness of abrasion-resistant steel typically ranges from 400 to 600 BHN.
Despite its higher initial cost, AR steel offers cost-effective long-term performance due to its durability and extended service life. It is widely used in industries such as mining and construction, where its superior abrasion resistance, weldability, and formability are essential.
Benefits of Abrasion Resistant Steel
The benefits of using Abrasion resistant steel are numerous, particularly in industries where high wear and tear are a constant challenge:
- Extended Service Life: AR steel significantly reduces downtime and maintenance costs due to its durability.
- High Wear Resistance: Its ability to withstand severe wear and tear makes it ideal for harsh environments.
- Toughness and Hardness: AR steel offers an excellent balance between hardness and impact toughness, suitable for demanding applications.
- Cost-Effective: Despite its higher initial cost, AR steel’s durability ensures long-term cost savings.
- Weldability: AR steel can be welded using standard methods, allowing for versatile fabrication.
- Formability: Available in both formable and non-formable grades to meet various manufacturing needs.
- Versatile Applications: Suitable for a wide range of industries, including mining, construction, and material handling.

How the Quenching & Tempering Process Makes AR Plates
The quenching and tempering process is essential for producing high-quality abrasion resistant steel plates, enhancing their hardness and toughness for demanding applications：
The quenching and tempering process begins with heating the steel plate to a high temperature to transform its microstructure into austenite. Then, the plate is rapidly cooled with water (quenching), which changes the grain structure to martensite, significantly increasing the steel’s hardness and strength. This process results in through-hardening, ensuring uniform hardness throughout the plate.
Finally, the steel is reheated to a lower temperature (tempering) to reduce brittleness and achieve the desired balance between hardness and toughness. This precise control of temperature and cooling rates is essential to produce high-quality AR plates that meet the stringent demands of wear-resistant applications.
