HRB: Rockwell B Hardness 100 kgf. HRC: Rockwell C Hardness 150 kgf. HRD: Rockwell D Hardness 100 kgf. HR15N: Rockwell Superficial 15 kgf. WebOct 15, 2024 · HRC means Rockwell hardness C scale, 2. HRC and HB are widely used in production. 3. The applicable range of HRC is HRC 20-67, which is equivalent to HB225-650. If the hardness is higher than this range, use Rockwell hardness A scale HRA. If the hardness is lower than this range, use Rockwell hardness B scale HRB.
