Product Description

Chrome Carbide Overlay Wear Plate are manufactured by welding one or multiple wear resistant layers on a medium or low carbon steel base plate.
The overlay alloy has a high amount of chromium carbide hard particles which makes the plate have good wear and impact resistance.

Overlay thickness range: 3-25mm
Wear plate size: 1500*3000, 1400*3000,1400*3400, 1400*3500, 2100*3500, customized.

Chrome Carbide Overlay Wear Steel Plate are used to make many complex wear parts to be positioned in high wear places.
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.

   Production Process

1. Raw material treatment

Billet preparation: Select high-quality steel plates for surface cleaning and composite lamination (if multi-layer wear-resistant structure is required).

2. Hot rolling molding

Heating rolling: After the slab is heated to the rolling temperature, it is rough-rolled and fin-rolled, and the rolling temperature and deformation are strictly controlled.

3. Heat treatment strengthening

Quenching + tempering: The key process, through rapid cooling and tempering treatment, to ensure that the steel plate reaches high hardness (such as HB400-HB600) and wear resistance.

4. Quality inspection

Levelling cutting: Hot levelling and cold levelling ensure flatness and precision cutting to the size required by customers.

Non-destructive testing: ultrasonic inspection of internal defects to ensure quality reliability.

5. Finished product processing

Surface processing: sandblasting, coating and other treatments according to demand to improve corrosion resistance.

Protective packaging: rust-proof packaging + reinforcement to ensure transportation safety.

   Factory Appearance

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.

   Packing And Shipping

We provide professional packaging and global shipping solutions for wear-resistant steel plates, ensuring safe and damage-free delivery from factory to destination. With customized protection (anti-rust, waterproof, shockproof), strict quality checks, and full export documentation, we support seamless cross-border procurement.

   Application Areas

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.
