Could you please check your grammar with a colleague, as its difficult to know what you are asking.

A lot more detail may be required to understand your problem, I gather that a iron shaft you're hardening is cracking after heating? It may help to know the shape of this shaft?

May be it is because of overheating. Please check the case thickness requirement & the actual being achieved with the heating & quenching cycle you are using. Also indicate the frequency/power rating , AISI code of shaft material, shape , whether any predrilled holes are present in the area to be hardened etc.
