Wear-resistant Steel

Wear-resistant steels are a class of specially alloyed and heat-treated steels with excellent resistance to wear.

The primary function of this steel is to resist constant friction, impact and wear.

Unlike ordinary steels, wear-resistant steels derive their resistance to wear from their unique chemical composition and manufacturing process.

Advantages of Using Wear Resistant Steel Plate

Abrasion Resistance

One of the primary advantages of wear resistant steel plates is their abrasion resistance. This quality is a result of the alloy composition of the steel and the heat treatment process that the steel undergoes. Wear resistant plates can withstand high levels of abrasion, making them ideal for use in applications with a risk of wear and tear.

Impact Resistance

Another advantage of wear resistant steel plate is their impact resistance. This quality allows the steel to absorb energy from impact rather than being damaged by it. This makes wear resistant plates ideal for applications with a risk of impact or collision.

Corrosion Resistance

Wear resistant steel plate also has corrosion resistance due to the addition of chromium to their alloy composition. This element forms a thin layer of chromium oxide on the surface of the steel, which acts as a barrier against corrosion.

Temperature Resistance

Wear resistant plates can also withstand high temperatures due to their high carbon content. This makes them ideal for applications with a risk of exposure to high temperatures, such as in foundries or furnaces.

Low Maintenance

Wear resistant steel plates require little maintenance, as they are not susceptible to rust or corrosion. This makes them ideal for use in applications where there is no easy access to maintenance or replacement.

Abrasion Resistant Steel Grades

There are a variety of wear resistant steel grades in the industry, including bespoke options on offer from manufacturers. So, the following sections highlight some common options, and is not an exhaustive list.

AR 200

AR200 typically has a hardness range between 170 and 250 BHN (Brinell Hardness Number). It offers moderate wear resistance and is suitable for general-purpose applications where some degree of resistance to wear is necessary. This medium-carbon manganese steel is often employed in applications such as truck liners, material chutes, and bulk handling equipment.

AR 235

The AR 235 or Manganese Steelis known for its high toughness and resistance to wear and tear. They usually contain 12-14% manganese and 0.8-1.25% carbon with a moderate abrasion resistance, but excellent resistance to impact. These steels have good weldability and formability properties making them versatile in various application. As a result, they are commonly used as crusher hammers, mining equipment, chutes and railroad track work.

AR 400

AR400 stands out due to its high abrasion resistance, typically ranging from 360 to 444 BHN. This grade is well-known for its good weldability and toughness, hence, making it a common choice in construction and mining equipment including bucket liners, wear plates, and hoppers. AR400 is ideal for applications where durability is crucial, effectively enhancing the performance of heavy machinery and material handling systems.

AR 450

For even greater demands, AR450 offers exceptional hardness, with a range from 420 to 470 BHN. This grade exhibits more surface hardness than AR400 while maintaining good ductility and formability. AR450 steel typically serves in applications involving moderate to severe wear, such as dump truck bodies, heavy equipment parts, and mining operations.

AR 500

AR500 provides excellent hardness, with a range from 477 to 534 BHN. This grade demonstrates very high abrasion and impact resistance. Hence, making it perfect for high-wear applications such as mining tools, construction machinery components, and military applications. The increased hardness of AR500 steel typically leads to lower machinability but superior performance in environments exposed to severe wear.

AR 600

For extreme wear resistance, AR600 reaches hardness levels from 570 to 625 BHN. This grade provides superior abrasion protection in applications such as armor plating for military vehicles, excavation buckets, and cutting edges. While its high hardness confers outstanding wear resistance, it also results in reduced formability, limiting its use in applications that require significant bending or shaping.
