Brinell hardness testing is to apply specified test forces onto the surface of test specimen through a quenched steel ball of certain diameter (Figure 1) and retain it for a specified period of time, then remove it and measure the diameter of indentation on the surface of specimen.
The table overview below presents the Brinell methods grouped by force-diameter index, the associated hardness range and recommended applications (materials). The higher the load factor, the harder the metals that can or should be tested with the methods within this force-diameter index.
Brinell and Rockwell Hardness Conversion Chart - These Conversion Tables presents data in the Rockwell A, B, C, D, E and F hardness range on the relationship among Brinell hardness, Vickers hardness, Rockwell and Shore Scleroscope hardness
76.9. These corrections are approximate only and represent the averages to the nearest 1/2 Rockwell number. 1: A 10 mm steel ball was used for 450 BHN and below. A 10 mm carbide ball was used above 450 BHN. Hardness vs Minimum Thickness Chart 55.
