Homework 4
Q1: 1.5 in diameter steel part is quenched in oil with no agitation. (H=0.20).
If we use a 4340; 4140; 8640; 5140; 1040 steel, what would be the hardness
number at the center of the part?
Q2: Determine the best quenching medium to produce a minimum hardness
of HRC 40 at the center of a 3.75 cm diameter 4320 steel bar.
