Under BHN 330, HRC 35: Normal BHN 330, HRC 35 to BHN 500, HRC 50: Special BHN means Brinell Hardness Number. HRC means Rockwell Hardness. The metal casting designers and foundries should consider the hardness range carefully, and arrange the production and machining process accordingly. As for...
Hardness can be measured in a variety of ways, such as Brinell Hardness (BHN), Rockwell Hardness (HRC), Bartholomew's Hardness (HV) and other indicators. They have different experimental methods and application scenarios. For metallic materials, Hardness testing is often performed using an indentat...

For quality control purpose, client have to test HRA, HRB or HRC hardness value of cast steel, stainless steel and cast iron, etc metal materials. 8’’ touch screen operation panel can display all test information: Rockwell hardness value, conversion value, test force, indenter type, etc. ...
The BHN can also be converted into the ultimate tensile strength (UTS), although the relationship is dependent on the material, and therefore is only an empirically based value. VICKERS HARDNESS The Vickers test is often easier to use than other hardness tests since the required calculations are...
Results reveled that the predicted tensile strength and elongation at the necking point were found approximately equal to their measured values 6.178 kN and 9.2mm respectively. The predicted Brinell hardness value was measured as 269 BHN. The estimated BHN value is equivalent to 26 HRC. Hence, ...
