The working condition of die-casting mould Was bad,during the work,its cavity Was subject to the impact of thermal shock of high temperature,high pressure and high speed metal fluid and cold shock of release agent.High cold and fatigue resistance,good wear resistance,corrosion resistance,impact toughness,red hardness and anti-linking were required.Through spheroidizing after forging,destressing annealing after machine-finishing,quenching,tempering,deep cold treating,the supplement tempering after precision working,superficial surface strengthening processing and stress-relieving processing during used,4Cr5MoVlSi steel can greatly satisfy the requirement,the service life is enhanced.
