The effect of second quenching temperature in zero time holding on 20MnV steel's strength and hardness was studied by the orthogonal regressive principle. The microstructure and property of the steel after austenite inverse phase transformation quenching in zero time holding were analyzed. Experiment results showed that the fine lath martensite of 20MnV steel was obtained through austenite inverse phase transformation quenching in zero time holding at 830°C-930°C. Within the range of Experiment's temperature, the structure of this steel quenched at 830°C is the finest. The microstructure will become coarse and the strength and hardness will become lower if the temperature goes up. The property of this steel can be increased remarkably by austenite inverse phase transformation quenching in zero time holding at lower temperature.
