Abstract An account was discussed of the nature of intergranular cracks appeared in the axial core of ingot of low carbon alloy steels, such as Cr5Mo, 12CrMoV and steel 10 on the basis of informations of industrial production and laboratory test. The experimental steel ingots weighing about 25 kg were examined under macroscopic observation, fractography, metallography and EMPA. It showed that the intergranular crack in axial core is true crack which seems to be related to the carbon content in steel owing to the high temperature δ→γ transformation on the solidification of ingot.
