The overlay alloy has a high amount of chromium carbide hard particles which makes the plate have good wear and impact resistance.
Wear plate size: 1500*3000, 1400*3000,1400*3400, 1400*3500, 2100*3500, customized.
We can provide wear plate cutting, bending, bolting, punching and welding according to customer's drawings.
1.Wear-resisting steel plate is composed of low carbon steel plate and alloy wear-resisting layer. When working, the matrix provides comprehensive properties such as strength, toughness and plasticity of resisting external forces, and the alloy wear-resistant layer provides wear-resistant properties that meet the requirements of specified working conditions.
2.Wear-resisting steel alloy wear-resisting layer and base plate are metallurgical combination. By means of special equipment and automatic welding process, the high-hardness self-protecting alloy wire is uniformly welded on the substrate, and the composite layers are one to two or even more. In the composite process, due to the different shrinkage ratio of the alloy, uniform transverse cracks appear, which is a significant feature of the wear-resistant steel plate.
3.The wear resistant layer of the alloy is mainly chromium alloy, while manganese, molybdenum, niobium, nickel and other alloys are added. The microhardness of carbide can reach above hv1700-2000, and the surface hardness can reach hrc58-62. Carbide alloy has a strong stability at high temperature, maintain a high hardness, but also has a good oxidation resistance, within 500℃ completely normal use.
4.The wear-resistant layer has narrow channel (2.5-3.5mm), wide channel (8-12mm), curve (S, W), etc. It is mainly composed of chromium alloy, while manganese, molybdenum, niobium, nickel, boron and other alloy components are added. With 40-60% carbide content, the microhardness can reach above HV1700 and the surface hardness can reach hrc58-62.

We can produce different sizes, thicknesses, widths and materials according to your requirements
1) Manufacturing Technique
Cutting large steel plates as your requirements to make the surface of the plate bright by miling and grinding, also can make holes and make angle degrees,and can weld by your drawing.
For the thickness under 30mm, cutting by laser; For thickness over 30mm, mainly OXY-cut, flame cutting.
For the thickness 200mm steel plate, because during the flame cutting, the temperature is very high, so the cutting parts steel plate might be broken at the angle part, then our workers will repair the angles to be good condition.
2) Test Before Delivery
We will control the quality from part of material steel plate, each plate produced will be have it is own identify label, quality will check the chemical component and physical property and then provide material test certificate. Size dimension will be checked and show pictures to customer to guarantee all goods will be meet requirement.
3) Application
Wear-resistant steel plate with high wear resistance and good impact performance is good, can be cutting, bending, welding, etc., can adopt welding, plug welding, bolt connection way to connect with other structures, such as the scene of the maintenance process possesses the characteristics of time saving, convenient and widely used in metallurgy, coal, cement, power station, glass, mining, building materials, brick and petrochemical industry, compared with other materials, has a high cost performance, has been favored by more and more buyers.
