The shape distortion problem which is caused in quenching the trapezoidal cross-sectioned tool steel was investigated. Using the computed results finite element method and those of the experiment are shown as follows:
1. The computed results show such similar value to the experimental can be easily expected according to the computed result.
2. In case of different cross-sectioned tool steel, its value of shape distortion decreases rapidly and its residual stresses increase as the cross-section area increases.
3. In quenching steel, its cooling rate becomes a little decreased on account of its transformation heat in the temperature of martensitic transformation.
