We would like to produce a 2-in.-thick steel wear plate for a rock-crushing unit.

Figure 13-21 The hardenability curves for several steels.

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.
