Difference between brinell and rockwell test
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 ... Webthe diameter of the indention. See Figure 1 for a schematic illustration of the Brinell hardness test. The Rockwell hardness number (HRX or RX) is determined from the differences of the indentation depths at the preload and the maximum load. The Rockwell number is read directly from the dial of the indenter, but the number must be reported ...
