What Is Wear-Resistant Steel Plate?

In manufacturing and construction, the composition and grade of the steel plate material used have a huge impact on the final product. Abrasion resistant steel plate is an ordinary steel plate with harder quality. Compared with ordinary high-strength structural steel plate, the durability time is about 4 times.

However, what makes it stronger, and how do you know when a project needs wear-resistant steel?

What is wear-resistant steel plate?

Abrasion-resistant (AR) steel plate is a high-carbon alloy steel plate. Due to the addition of alloys, AR has formability and weather resistance. Due to the addition of carbon, its hardness is higher.

The addition of carbon during the formation of the steel plate significantly increases the hardness and toughness of the steel plate, but the strength decreases. Therefore, AR plates are used under conditions where wear and abrasion are the main causes of failure. AR plates are not perfect in structural construction applications, such as supporting beams in buildings or bridges.

Common applications for AR plates include dump truck liners, grates, buckets, construction accessories, conveyor belts, body armor and ballistic panels (and as targets for shooting ranges).

How is abrasion-resistant steel made?

The main alloying elements of abrasion-resistant steel are iron (Fe) and carbon (C), although various low-content and trace minerals are added to adjust the chemical and mechanical properties of the final product. First, the raw iron is melted in a blast furnace, and then carbon is added to the melt. Depending on the application area, additional elements such as silicon (Si), nickel (Ni) and molybdenum (Mo) can be added at this stage. Abrasion-resistant steels can contain as much as 0.18-0.30% carbon, and they are medium and low carbon steels.

Once the proper composition is reached, the molten mixture is formed and cut to the proper size. Wear-resistant steel is generally not suitable for quenching and tempering because heat treatment has the risk of reducing material strength and wear resistant properties.

The wear resistance qualities of the abrasion-resistant steel alloy is obtained by strictly controlling the basic mechanical properties of the material. The most important of these are:

Hardness (Brinell hardness), which determines the ability of the material to withstand impact.

Strength (yield and tensile), which determines the structural integrity of the material under high loads.

Abrasion is used to define any process in which the surface of a material wears away due to friction. This may occur where the surface is worn, scratched, or gradually worn out in contact with other parts or materials. This is a common problem in heavy industry, but it can also be a problem for more complex machinery associated with high duty cycles or challenging operating conditions. The solution to this phenomenon is to maintain adequate lubrication of the mating surface, or use suitable wear-resistant materials to optimize performance.

Abrasion resistant steel is an optimized alloy that can withstand surface wear, which can lead to a series of unexpected consequences, from simple aesthetic damage to complete structural damage.
