HRC – diamond penetrator 120°, load 1470 N (150 kgf) duration 30 seconds. Table B is a comparison between HRB, BH, HV and Rm. Table A is the comparison between Rockwell C hardness, Brinell hardness, Vickers hardness and tensile strength (Rm). The following two conversion tables are from the standard ASTM A370. Formula A – Convert HRC into HB Rockwell C Hardness (HRC)įormula B – Convert HRB into HB Rockwell B Hardness (HRB) Rockwell hardness (HRC and HRB) and Brinell hardness (HB or BHN) are most commonly used for steel and iron castings.Īlthough there is no accurate conversion table and formula, Yide Casting Foundry recommends the following formula and comparison table based on experience and standards. Hardness is very important for the production of rough metal castings, heat treatment and machining processes. In this article, we will show you the conversion of Rockwell Hardness (HRC, HRB) to Brinell Hardness (HB or BHN). Yide Casting a professional iron casting manufacturer & supplier, provides both iron casting made & machining services for decades years.
