Question:
We would like to produce a 2-in.-thick steel wear plate for a rock-crushing unit. To avoid frequent replacement of the wear plate, the hardness should exceed HRC 38 within 0.25 in. of the steel surface. The center of the plate should have a hardness of no more than HRC 32 to ensure some toughness. We have only a water quench available to us. Design the plate, assuming that we only have the steels given in Figure 13-21 available to us.

Rockwell C hardness 70 60 50 40 30 20 0 4340 10 20 Jominy distance (th of an inch) 8640 9310 1080 4320 1050 30
