A 10-mm-diameter Brinell hardness indenter produced an indentation 2.50 mm in diameter in a steel alloy when a load of 1000 kg was used. Calculate the HB of this material.
Answers: 1
is the load measured in kilograms-force, 
is the diameter of indenter measured in millimeters and 
is the diameter of indentation measured in millimeters.![HB=\frac{2\cdot (1000\,kgf)}{\pi\cdot (10\,mm)^{2}}\cdot \left[ \frac{1}{1-\sqrt{1-\frac{(2.50\,mm)^{2}}{(10\,mm)^{2}} } } \right ]](/tpl/images/0537/2625/c59db.png)
