Abstract：The effect of heat treatment on property of 3Cr13MoCu martensitic stainless steel was studied by metallographic microscope observations, vickers hardness measurement, antibacterial test and scanning electron microscopy (SEM) observation. The results showed that after solution treatment, the steel samples have high hardness, but the antibacterial rate were lower. increase of the aging temperature, the antibacterial rate was increased, but the hardness declined. After solution at 1080 ℃ for 30 min, water cooling to room temperature + aging at 700 ℃ for 8 h, air cooling to room temperature + solution at 1000 ℃ for 5 min, oil cooling to room temperature. the stainless steel have both excellent antibacterial performance and hardness.
