Effects of heat treatment on the property of r85 steel plate was investigated by means of quenching and tempering process combining with the metallurgical microstructure and alloying agent analysis. The results show: the property of r85 steel plate is significantly effected by the quenching process, and the good hardenability can be obtained in the quenching temperature range of 930-940°C. When tempering temperature is below 700°C, the strength decreases slightly with the tempering temperature rises. When tempering temperature is above 700°C, the strength decreases quickly. The hardenability and resistance of r85 steel plate is enhanced with the addition of Mn, Mo and Nb alloy agent.
