Wear-resistant steel plates are mainly divided into 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 surfacing welding on a layer of ordinary steel plates. , Make a layer of wear-resistant alloy, so it is also called bimetal wear-resistant steel plate.
No matter what kind of wear-resistant steel plate, it may look the same as ordinary steel plate on the surface, but its function and composition are far from it. So, what are the differences between wear-resistant steel plates and ordinary steel plates?
1. Different steel grades
All steel plates are poured with molten steel, and the plates are extruded after cooling. According to the thickness, they can be roughly divided into thin plates, medium-thick plates, and extra-thick plates. 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, bimetal wear-resistant steel plates are special and belong to reworked steel plates.
2. Different uses
Wear-resistant steel plates have excellent wear resistance and can be used in high-wear conditions. The service life is incomparable to ordinary steel plates. Its impact resistance and toughness also bring higher safety. Therefore, it is very popular. You can often see wear-resistant steel plates in mining, machinery, coal mines, docks, cement and other industries, and can greatly improve work efficiency and reduce costs.
3. Different rust points
When the wear-resistant steel plate and ordinary steel plate are not rusted, it is difficult for everyone to distinguish. Therefore, when purchasing, you must check the quality assurance certificate and other documents provided by the manufacturer, or take samples to a third-party organization for inspection.
When the steel plate rusts, it can be distinguished by the traces of rust. The rust water of ordinary steel plate is large, and the rust spots are large and thin, while the rust spots of wear-resistant steel plates are relatively small and dense.
4. The price is different
Wear-resistant steel plates are special steels. The production process and technical requirements are much higher than those of ordinary steel plates. Therefore, the cost is naturally different. When buying wear-resistant steel plates, you must pay attention to choosing professional manufacturers and do not be regarded by unscrupulous merchants. The ordinary steel plate is posing as a huge loss.
