WebFor instance, converting from a Rockwell hardness test on the C scale (HRC) to a Brinell hardness test value requires using the formula: BHN = 5.970 x (HRC + 104.7). This formula gives an approximate value for the Brinell hardness value, and quality assessment professionals use it to create the conversion tables and charts for instant conversion. WebBHN is designated by the most commonly used test standards (ASTM E10-14 and ISO 6506–1:2005) as HBW (H from hardness, B from brinell and W from the material of the indenter, tungsten (wolfram) carbide). In former …
