Hardness Conversion Calculator - Machining Doctor

The test is done by measuring the surface area of the indentation created by a diamond in the shape of a square-based pyramid. The HV number is equal to the force divided by the area (F/a). Carbide grades are usually in the range of 1,300-1,900 HV. Ceramics can reach a hardness of 2,000 HV, CBN up to 3,000 HV, and PCD up to 6,000 HV.
