2021-08-05

Surfacing wear plate is a commonly used material in industrial and mining enterprises. It is a new type of alloy lined wear-resistant material, which has been widely used in many complex industrial mines. Due to its good superiority. It is loved by more and more miners. Hardfaced wear-resistant composite steel plate is characterized by high abrasion resistance, good impact resistance, good corrosion resistance and high cost performance, so it is cost-effective and has a long service life. The following gives you a specific introduction to the characteristics of the surfacing wear resistant plate to help you understand the

Hardfaced wear-resistant composite steel plate is characterized by high abrasion resistance, good impact resistance, good corrosion resistance and high cost performance, so it is cost-effective and has a long service life. The following gives you a specific introduction to the characteristics of the surfacing wear-resistant plate to help you understand

1. High wear resistance

The chemical composition of the alloy layer contains 4 ~ 5% carbon and 25 ~ 30% chromium. The volume fraction of Cr7C3 carbide in its metallographic organization is more than 50%, and the macro hardness is HRC 56 ~ 62,. The hardness of chromium carbide is HV1400 ~ 1800, which is higher than the stress hardness in sandstone. Due to the vertical distribution of carbides along the wear direction. Compared with casting alloys with the same composition and hardness. Wear resistance is more than doubled. Wear resistance compared to several typical materials is as follows.

(1) With mild steel; 20 to 25:1

(2) With high manganese steel; 5~10:1

(3) With tool steel; 5~10:1

(4) cast high chromium cast iron; 1.5~2.5:1

2. Good impact resistance

Hardfaced wear-resistant composite steel plate reflects the superiority of bimetallic,. The wear-resistant layer resists the abrasion of the abrasive medium, and the matrix bears the load of the medium, which has good impact resistance.

3. Good heat resistance

The wear-resistant layer is recommended to be used at ≤600℃. If vanadium, molybdenum and other alloys are added to the alloy layer. It can withstand high temperature wear at ≤ 800℃.

Recommended temperatures are as follows.

Ordinary carbon steel substrate is recommended to be used at temperatures not higher than 480℃;

Low alloy heat resistant (15CrMo, 12Cr1MoV, etc...). It is recommended to use the substrate at a temperature not higher than 540 ℃

4. Good corrosion resistance

The alloy layer of the surfacing wear plate contains a high proportion of chromium metal,. Therefore, it has a certain degree of rust resistance and corrosion resistance.

5. High cost performance

Due to the above features, the surfacing wear plate has a high cost performance ratio. Compared with high manganese steel disk head, the service life can be increased by more than 5 times. Maintenance costs and downtime losses are greatly reduced. So it is favored by more and more people. Various types of industrial and mining enterprises in the import of equipment, can give priority to the purchase of wear-resistant surfacing wear-resistant composite steel plate, in the long run can greatly save the cost of enterprises. Hardfacing wear-resistant composite steel plate reflects the superiority of bimetallic, wear-resistant layer to resist the wear of abrasive media, the matrix to withstand the load of the media. Wear-resistant surfacing wear-resistant composite steel plate enterprises can do a good job of publicity and promotion, the establishment of production and marketing of the production of one road to improve economic efficiency.
