ASTM E140 (conversion HRc -> HV -> HB -> HSc). ASTM E448 standard only differentiates equipment by the reading method (rebound or dial). Theoretically, hardness values are announced as identical. However, some non-official tables show a difference.

Rockwell Hardness (HRC, HRB) to Brinell Hardness (HB or BHN) Conversion Hardness is very important for producing rough metal castings, heat treatment and machining process. Rockwell Hardness (HRC and HRB) and Brinell Hardness (HB or BHN) are most
