Jackhammer bits may have been made from any of several types of steel.

I'v had good luck by normalizing them (cool from criticaltemperature on the
forge) and them tempering them to just past brown or to light blue in
water. I have never had one crack or be soft from this. I make one every
time I demo on the Treadle Hammer and Q&T it. But it depends on the metal
in the bit to start with.
