Due to the problem of the oxide layer and surface flatness on the surface of the wear-resistant steel plate, when testing the wear-resistant plate, it is best to mill off 1.0-2.5mm on the surface of the steel plate, and then perform hardness inspection on this surface. Generally, we recommend that you mill off 2.0mm for hardness inspection.
