Stainless steel ball bearings p 8085. Stainless steel ball bearings ρ 8085 kg m 3 and c p 0 480 kj kg c having a diameter of 1 2 cm are to be quenched in water at a rate of 800 per minute. The balls leave the oven at a uniform temperature of 900 c and are exposed to air at 25 c for a while before they are dropped into the water. Stainless steel ball bearings 8085 kg m 3 and c p 0 480 kj kg c having a diameter of 1 2 cm are to be quenched in water at a rate of 800 per minute the balls leave the oven at a uniform temperature of 900 c and are exposed to air at 25 c for a while before they are dropped into the water. If the temperature of the balls drops to 850 o c prior to quenching determine the rate.
