WebRockwell scale B is the hardness measuring scale with the symbol HRB. The range of the scale lies between 20-100HRB with an intender (1.5875mm ball). When the hardness of the sample is less than 20HRB, the deformation of the sample lasts for a long time, and the scale on the watch will move slowly, making it difficult to measure accurately.
