Advantages of using impact resistant and wear-resistant steel plates:
1. Good impact resistance:
The substrate of the impact resistant steel plate is made of ductile materials such as low-carbon steel or low alloy steel, stainless steel, etc., reflecting the superiority of bimetallic materials. The wear-resistant layer resists the wear of the wear medium, and the substrate bears the load of the medium, thus having good impact resistance. It can withstand the impact and wear of high drop hoppers in the material conveying system.
2. Excellent wear resistance
The chemical composition of the alloy wear-resistant layer includes a carbon content of 2.5% -3.5% and a chromium content of 40% -50%. The volume fraction of Cr7C3 carbide in its metallographic structure is over 50%, with a macroscopic hardness of HRC58-63 and a hardness value of HV1700-2000. Due to the vertical distribution of carbides in the wear direction, even compared to cast gold with the same component hardness, the wear resistance is improved by more than three times. The comparison of wear resistance with several typical materials is as follows:
(1) And low alloy carbon steel; 20～25：
(2) Paste steel with ceramics; 12~18
3. Improving economic benefits: reducing downtime and improving equipment operation rate
Improve equipment efficiency, reduce downtime maintenance losses, increase production capacity, and increase efficiency
