After keep the temperature 40-60min, then using it is air-cooled and it is air-cooled combine cooling room temperature, first pass through and air-cooled be cooled to 8-10 DEG C/s
300-350 DEG C, then it is air-cooled to room temperature；
Step 7: heat treatment: annealing, tempering, solution treatment, wherein annealing temperature is 550-650 DEG C, time 1-2h；Tempering temperature
Degree is 450-540 DEG C, time 30-40min；Solution treatment: temperature is 680-750 DEG C, time 2-3h；
Step 8: component is placed in nitriding furnace and is passed through NH into furnace by nitrogen treatment3, furnace is warming up to 530-550 DEG C, is protected
Hold 20-24h.
