HEAT TREATMENT PROCESS CHARACTERISTIC ON AIR-CONDITION SCREW
The air condition screws were heat-treated in vacuum furnace,in which the quenching temperature was 1 050 ℃ and the tempering temperature was 200 ℃,and the quenching medium was compressive air. The microstructure of screws was observed and analyzed. The results showed that,the processing prompt screw to form the balance microstructure,and finally obtained optimized plastic,toughness and corrosion resistance.
