摘要（英）：

The invention discloses a heat treatment process of a 42CrMoE piston rod. The heat treatment process is characterized by comprising the following steps that (1) a 42CrMoE piston rod material is subjected to forging and stamping for forming; (2) the 42CrMoE piston rod material is subjected to hardening and tempering; and (3) the 42CrMoE piston rod material is subjected to high-frequency quenching at the temperature of 1050-1200 DEG C for 2 hours, and is subjected to air cooling to room temperature after quenching. According to the heat treatment process of the 42CrMoE piston rod, the surface hardness and the wear resistance of the material are improved, the corrosion resistance of the material is improved, the stability of temper resisting of the material is improved, and the heat treatmentprocess is used in industrial engineering.
