2. 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 3.933- mm-diameter impression in the iron surface. a. Calculate the BHN of this alloy. (The correct units for the Brinell equation are kilograms for load and millimeters for diameters.) b. Predict the tensile and yield strengths (5 Points) 1.200 Grade 120-90-62. oil-quenched 160 1.000 120 100-70-03. air-quenched 80-35. 06. as cast 65.45-12. annealed SOO Strength, MPa Strength, ksi SO 600 400 40 00 Tensile strength 200 Yield strength 60_10-18. annealed 0 161 IND 200 220 240 260 280 Hardness.
