The wear resistant hard-faced plates are commonly used in wear engineering for the purpose of providing protection wherever wear and corrosion resistance is required. wear resistant hard-faced plates are prepared by overlaying a high hardness alloy onto a substrate to form a composite material with excellent wear resistance. composite material with excellent abrasion resistance.
The following are some common overlay materials for wear-resistant hard-faced plates and their properties:
1. High-chromium cast iron alloy: High-chromium cast iron alloy has excellent wear resistance and corrosion resistance, commonly used alloy composition is Cr-Ni-Mo-W-V and so on. Its hardness is generally between HRC55-65, with high strength and wear resistance. It is mainly used in coal mines, iron mines, cement and other industries.
2. High-chromium white iron alloy: High-chromium white iron alloy is a kind of material with very high wear resistance, and its alloy composition is mainly Cr and C. Its hardness can reach HRC60-65, and it has very high wear resistance and anti-impact performance. It is mainly used in grinding ball mills, mining hoppers and other high wear-resistant occasions.
3. High manganese steel alloy: high manganese steel alloy is a common surfacing wear-resistant material, with excellent wear resistance, impact resistance and good plasticity. Its hardness is generally between HB200-250 with high strength. It is mainly used in crusher, screening equipment and other grinding and sorting fields.
Selection of suitable surfacing wear-resistant alloy materials should be considered according to specific application scenarios, the following points are important factors in selecting surfacing wear-resistant alloy materials:
1. Wear resistance requirements: Different occasions have different requirements for wear resistance, some occasions need to resist heavy impact and wear, while other occasions may only need to resist light wear. According to the actual wear resistance requirements to select the appropriate surfacing wear-resistant alloy materials.
2. Working conditions: Consider the temperature, humidity, and wear patterns of the working environment. For example, on some occasions there may be high temperatures or corrosion and other special working conditions, you need to choose the alloy material that can withstand these conditions.
3. Processability: Consider the processability of the alloy material, including cutting, welding and installation. Select the appropriate material according to the specific process requirements.
4. Economy: According to the budget constraints and performance requirements to select economically reasonable cladding wear-resistant alloy materials, in order to maximize the cost-effective.
In summary, the selection of suitable wear resistant hard-faced plates should fully consider the wear resistance requirements, working conditions, processability and economy to meet the needs of specific applications. For actual selection, professional technicians or suppliers can be consulted for more detailed advice and guidance.
