HRC and HV are both commonly used as measures of hardness in the metal industry. To convert between the two, you can use the following conversion table: HRC HV 20 207 25 238 30 269 35 300 40 332 45 363 50 394 55 425 60 486 65 581 70 677 75 772 80 867 85 963 90 1058 95 115...
The test method used is either HRC or HV30. The hardness variation along the test surface is a result of microstructural variation that arises as the cooling rate decreases with the distance from the quenched end. The harder the material at a given distance from the end, the higher the ...
