Abstract
This paper mainly discusses the effects of heat treatment of Q345B steel at 900~1060 quenching +450 tempering treatment on the performance of steel. After heat treatment, the steel samples of different treatments were taken to observation and test to get the statistical analysis of test results by changing heat treatment on the properties of the steel. Results show that the quenching treatment enhances the strength and hardness of the steel significantly. After tempering at 450 , the plasticity and toughness of steel has also been picked up. The steel has good corrosion resistance when the quenching at 980~1020 . Considering the strength, hardness, plasticity and toughness, and the heating temperature, production practice, the heat treatment treatment of quenching at 940 +450 tempering of steel samples, can make the steel obtain excellent comprehensive properties, which is of great economic significance and practical significance.
