Wear-resistant steel plates are mainly divided into two types: alloy wear-resistant steel plates and composite wear-resistant steel plates. Alloy wear-resistant steel plates are nm400, JFE-EH400, DILLIDUR 400, etc. Composite wear-resistant steel plates are made by surfacing a layer of ordinary steel plates. , make a layer of wear-resistant alloy layer, so it is also called bimetal wear-resistant steel plate.
No matter what kind of wear-resistant steel plate it is, it may not look much different from ordinary steel plates on the surface, but its functions and ingredients are far different. So, what are the differences between wear-resistant steel plates and ordinary steel plates?
1. Different steel types
All steel plates are poured with molten steel and extruded after cooling. They can be roughly divided into thin plates, medium-thick plates, extra-thick plates, etc. according to their thickness. According to the function and composition, it can be divided into ordinary steel plate, alloy steel plate, wear-resistant steel plate, stainless steel and so on.
Among them, wear-resistant steel plates belong to a category of steel plates with excellent wear resistance, impact resistance, and toughness. Among them, bimetallic wear-resistant steel plates are special and are reprocessed steel plates.
2. Different uses
Wear-resistant steel plates have excellent wear resistance and can be used under high-wear conditions. Their service life is unmatched by ordinary steel plates. Their impact resistance and toughness also bring higher safety. Therefore, it is very popular. Wear-resistant steel plates can often be seen in mining, machinery, coal mines, docks, cement and other industries, and can greatly improve work efficiency and reduce costs.
3. Different rust spots
It is difficult to tell the difference between wear-resistant steel plates and ordinary steel plates when they are not rusty. Therefore, when purchasing, you must check the quality guarantee certificate and other documents provided by the manufacturer, or take samples to a third-party agency for inspection.
When a steel plate rusts, it can be identified based on the traces of rust. Ordinary steel plates have a lot of rust water, and the rust spots are large and sparse, while wear-resistant steel plates have relatively small and dense rust spots.
