Rockwell hardness is an indicator used to determine the hardness value based on the depth of plastic deformation of the indentation, with a hardness unit of 0.002 millimeters. The use of different indenters and test forces in Rockwell hardness testing results in different combinations, corresponding to different scales of Rockwell hardness. There are three commonly used scales, which cover almost all commonly used metal materials
