Introduction Of Abrasion-Resistant Steel Plate (AR plate)
What is AR plate?
Abrasion-resistant steel plate (AR plate) is a special plate product of high-carbon alloy steel plate, which is mainly used for work that will produce large-area wear. Wear-resistant steel plates are welded on the surface of low-carbon steel or low-alloy steel to form one or more layers of alloys with higher hardness, weather resistance and higher wear resistance, and have better plasticity and toughness. The thickness of this alloy wear-resistant layer is generally 1/3 ~ 1/2. It is adding carbon, manganese, nickel, chromium, boron and other alloys to the steel plate to relatively increase the hardness and toughness of the steel plate. Adding carbon can increase the hardness of the steel plate, but if we add too much carbon to the steel plate, it will become brittle and reduce the tensile strength.
Commonly used in:
Because the wear resistant plate mainly has high wear resistance and good impact performance, it is suitable for welding, cutting, bending, etc. From the point of view of its material, the cost performance is very high, so it has been welcomed by the public in recent years. It is widely used in industrial fields with more extreme environments, such as heavy industrial equipment, mining, electric power, agriculture, construction, and cement industries. This kind of wear-resistant steel plate is very convenient and time-saving in the repair process.
AR plate characteristics
The advantages of wear-resistant steel plates are as follows:
1) Good wear resistance
The wear-resistant steel plate has a layer of alloy wear-resistant layer on the outside, and the composition of this layer of alloy wear-resistant layer contains chemical elements such as carbon and chromium, making it twice the hardness and wear resistance of ordinary steel plates.
2) Strong impact resistance
According to what we mentioned above, there are mainly two layers of wear-resistant steel plates, the base material is low-carbon steel or low-alloy steel plate and a layer of alloy wear-resistant layer. The outer alloy wear-resistant layer can be used to resist the wear of the wear medium, and the inner base material can withstand the load of the medium, so as to achieve good impact resistance. At the same time, it can withstand the impact and abrasion of the high drop hopper in the material conveying system.
3) Good heat resistance
Adding vanadium, molybdenum and other alloys to the alloy wear-resistant layer can increase the heating degree of the steel plate. Approximately can withstand high temperature wear ≤800℃.
4) Superior corrosion resistance
Since the alloy layer of the wear-resistant composite steel plate contains a large amount of metallic chromium, it has good rust and corrosion resistance.
5) Convenient processing performance
The wear-resistant steel plate can be processed into various industrial parts through cutting, bending, welding, etc. according to the needs of the project.
Abrasion-resistant steel plates have higher hardness than ordinary steel plates, and have stronger wear resistance and corrosion resistance.
