description The invention relates to a heat treatment method capable of improving low-temperature impact toughness and grain size of a 35CrNi4Mo material forge piece. A heat treatment mode of normalizing, quenching, subcritical quenching and high-temperature tempering is adopted. Normalizing, namely heating to 880-900 DEG C, keeping the temperature after uniform temperature, discharging from the furnace, and carrying out blast cooling; quenching, heating to 880-890 DEG C, carrying out heat preservation after uniform temperature, discharging, and carrying out oil cooling; carrying out subcritical quenching, heating to 785-795 DEG C, carrying out heat preservation after uniform temperature, discharging from the furnace, and carrying out oil cooling; and tempering at high temperature, heating to 625-665 DEG C, preserving heat, discharging from the furnace, and carrying out air cooling. The method can be used for heat treatment of 35CrNi4Mo material forgings with the diameter phi smaller than or equal to 400 mm. The 35CrNi4M
