Wear Resistant Steel is a great steel for toughness but not very good for initial hardness. It starts out with a hardness of only 250 Brinell, which is very low. Unless it is impacted, the steel will quickly wear away. However, with impact, it will work harden to over 550 Brinell. In other words, with impact, it will become twice as hard and very tough, making it the perfect wear resistant steel choice for use in high-impact environments.

The wear-resistant steel plate is composed of a low-carbon steel plate and an alloy wear-resistant layer. The alloy wear-resistant layer is generally 1/3 to 1/2 of the total thickness. When working, the matrix provides comprehensive properties such as strength, toughness and plasticity against external forces, and the alloy wear layer provides wear resistance that meets the requirements of specified working conditions.

There is a metallurgical bond between the alloy wear-resistant layer of the wear-resistant steel plate and the substrate. Through special equipment and an automatic welding process, the high-hardness self-shielding alloy welding wire is uniformly welded on the substrate. The composite layer has one to two layers or even multiple layers. During the composite process, due to the different shrinkage ratios of the alloy, uniform transverse cracks appear. It is a remarkable feature of wear-resistant steel plates.
