Еxample (a) A Brinell hardness measurement is made on a ductile iron (100– 70–03, air- quenched) using a 10-mm-diameter sphere of tungsten carbide.A load of 3,000 kg produces a 3.91-mm-diameter impression in the iron surface. Calculate the BHN of this alloy. (The cor- rect units for the Brinell equation of Table 6.9 are kilograms for load and millimetres for diameters.)
