For instance, tensile strength may reach a maximum following some particular curing cycle, whereas elongation at that point is well along a steeply decreasing curve. Thus, the optimum curing cycle for molding of a given compound must be determined...

Figures 24.14 to 24.16 show examples of hardness as a function of tempering temperature for A-2, H-13 ( Ref 24.39 ), and several high-speed tool steels ( Ref 24.40 ), respectively. The curves for the A-2 and H-13 are based on double tempering and that of the high-speed steels...
