The effect of shot-peening on the fatigue strength of decarburized Si-Mn spring steels was examined by the rotary-bending and the reversed torsional method. The effect was very striking and it was observed that the endurance limit at 10^7 cycles of decarburized steels, which was reduced by about 50 per cent of limit of the polished specimen on account of the soft layer only about 0.05 mm in thickness, increased by 40〜50 per cent as the result of shot-peening of the decarburized layer. It might be possible to recover the strength in the non-decarburized state by increasing the peening intensity.
