Equipment uptime is pivotal, particularly in industries that have high impact and abrasion like pulp & paper, mining, and construction. AR steel plates help address these needs. Placing abrasion resistant steel plates in high wear areas of your machinery can help make your equipment more durable, increasing uptime and profitability.

However, not every abrasion resistant steel plate is created equal. Alloyed steel plates, such as Tricon’s Tri-Braze®, allow businesses in these industries to greatly extend equipment life and reduce time spent on maintenance and repairs. In order to help you understand the different types of AR steel plates and their use cases, we’ve assembled a helpful guide below.
What are Abrasion Resistant Steel Plates?
Abrasion resistant steel plates are designed to withstand more wear and tear, abrasion, and impact than a traditional structural or mild steel plate. While traditional structural steel is an alloy of iron and carbon with small additions of manganese and silicon, standard AR steels use higher levels of these elements to achieve higher hardness and wear resistance. Alloyed abrasion resistant steels can also include other elements like chromium, nickel, molybdenum, boron and titanium added during the steel production process, changing the molecular makeup, and ultimately the balance of properties of the end product.Commodity AR steel plates are rated based on their surface hardness as measured by a Brinell Hardness Tester. The higher the calculated Brinell Hardness of a material, the harder the material’s surface. Materials with a higher Brinell Hardness Number (BHN) will generally have higher resistance to abrasion. This grading system gives a general indication of a material’s service life under abrasive conditions, but suffers from two major flaws. First, being only a surface test, it gives no indication of the hardness in the plate’s middle. Second, it does not give any indication of the material’s impact resistance and tendency to crack during welding.
There is typically a tradeoff when it comes to hardness. As the hardness of a carbon/manganese/silicon-based material increases, the ductility, weldability, formability and impact resistance of that material decreases. This means that steels with higher hardness levels can be more difficult to form, fabricate or weld. When you are selecting an AR steel plate, the best option strikes a balance between the level of abrasion/impact resistance and workability.

Introduction
Wear resistant steel plates are essential materials in industries where equipment is subjected to extreme abrasion and impact. Their primary purpose is to enhance the durability of machinery, reducing downtime and maintenance costs. Choosing the right wear resistant steel plate can greatly improve the performance of your operations, whether in mining, construction, or manufacturing.
This guide explores the properties, benefits, and applications of wear resistant steel plates, helping you make informed decisions for your specific needs.
What Is a Wear Resistant Steel Plate?
Definition
A wear resistant steel plate is a type of steel designed to withstand abrasion, impact, and harsh environments. It is commonly used in industries where machinery encounters abrasive materials, such as mining, construction, and transportation.
Key Properties
- High hardness, typically ranging from 400 HBW to 600 HBW.
- Excellent toughness to absorb impact.
- Exceptional resistance to wear and abrasion.
- Good formability for cutting, bending, and welding.
Factors to Consider When Choosing a Wear Resistant Steel Plate
Application Requirements
The application determines the level of hardness and toughness needed. For example, mining equipment often requires higher hardness, while construction machinery may need a balance of toughness and abrasion resistance.
Material Grade
Different grades offer varying levels of wear resistance:
- AR400 is suitable for moderate wear.
- AR500 is ideal for high abrasion conditions.
- AR600 is designed for extreme wear environments.
Thickness
The plate’s thickness impacts its durability and weight. Thicker plates are more wear-resistant but may require special handling during fabrication.
Processing and Machining
Ensure the plate can be easily cut, drilled, or welded to meet your specific design requirements.
