Absorbed energies by non-notch-impact bend at 0°C and bend angles by non-notch-impact and slow bend of mild steels, of which ultimate tensile strengths are 46 and 49 kg/mm2, were investigated for various cooling times from A3 point to 500°C. In the neighbourhood of the critical cooling time Cf', the bend angle decreased with decrease of the cooling time for both steels. And both steels showed the decrease of absorbed energy over the critical cooling time Cf'
