| Characteristics |
Impact resistant wear plates, Independent R&D, suitable for medium to high impact. |
| Composition: |
The wear-resistant composite steel plate is a layer or multiple layers of wear-resistant alloy containing a large number of chromium carbide hard particles deposited on the medium and low carbon steel substrate, and some special elements are added to form carbides with special effects. |
| microstructure: |
The volume fraction of Cr 7C3 carbide in the metallographic structure of the wear-resistant layer reaches more than 50%. |
| Hardness: |
According to the thickness of the wear-resistant layer and the application, the surface hardness of the wear-resistant alloy ranges from HRC56-65, and the micro-hardness of chromium carbide is up to HV1800. |
| Abrasion resistance: |
Laboratory results show that the wear resistance of high-chromium surfacing wear-resistant composite steel is 20 times that of low-carbon steel and 8 times that of heat-treated wear-resistant steel. ASTM-G65A dry sand wear test surface wear and 75% deep wear test The data shows that it has high wear resistance. |
| Flatness: |
The flatness is controlled at soil 3mn/m. |
| Thickness error: |
The thickness of the wear-resistant layer is uniform, and the thickness tolerance is 0-0. 5mm. |

High chromium alloy wear-resistant plate, it is a plate product specially used for large-area wear conditions. It is formed by surfacing welding on ordinary steel plate, heat-resistant steel plate, and stainless steel plate with a volume fraction of 50% The above alloy wear-resistant layer based on Cr7C3 carbides. Wear-resistant steel plates have high wear resistance, impact resistance, deformability and weldability. They can be processed into engineering parts like steel plates, such as crimping, cutting and drilling, and processed into engineering parts to meet the needs of wear-resistant industrial and mining operations.
Performance characteristics:
- High wear resistance: Wear tests show that the wear resistance of the wear-resistant composite board is more than 20 times higher than that of low-carbon steel, and more than 5 times higher than that of stainless steel and high-manganese steel.
- High impact resistance: Due to the use of soft steel substrate, the wear-resistant composite board has high impact resistance, which fully reflects the advantages of composite materials both wear resistance and impact resistance.
- Convenient processing performance: The wear-resistant surfacing composite steel plate can be deformed and welded, and can be easily processed into various wear-resistant parts like ordinary steel plates.
High performance and price ratio: Although the surface cost of the wear-resistant surfacing composite board is increased, the performance and price ratio of the ordinary materials is about 2 to 4 times higher than that of ordinary materials, taking into account the service life of the parts, maintenance costs, and downtime losses. Due to the reasonable use of materials, the price of wear-resistant surfacing composite board is 50% lower than that of manual surfacing of the same material.
Application range of High chromium alloy wear-resistant plate
