Wear-resistant plate is steel, and its main components are low-carbon steel plate and alloy wear-resistant layer, of which the alloy wear-resistant layer occupies 1/2~1/3 of the thickness of the entire plate; because the main chemical component is chromium, it can reach The content of all materials is 20%~30%, so its wear resistance is very good.
Second, the characteristics of wear-resistant plates
1. Impact resistance: The impact resistance of the wear-resistant plate is very good. In the process of conveying materials, even if there is a very high drop, it will not cause too much damage to the wear-resistant plate.
2. Heat resistance: Generally, wear plates below 600 degrees can be used normally, but if we add some vanadium and molybdenum when making wear plates, there is no problem at high temperatures below 800 degrees.
3. Corrosion resistance: Because the wear plate contains a large amount of chromium, the corrosion resistance of the wear plate is excellent, and there is no need to worry about corrosion.
4. Cost-effectiveness: The price of wear-resistant plates is 3~4 times that of ordinary steel plates, but the service life of wear-resistant plates is more than 10 times longer than that of ordinary steel plates, so its cost-effectiveness is relatively high.
5. Convenient processing: The weldability of the wear-resistant plate is very strong, and it can also be easily bent into various shapes, which is very convenient to process.
