In the paper, the experimental study on microstructure transformation of bainite steel with different contents of Mn and Cr using full automatic transformation measuring apparatus is introduced. The effects of different contents of Mn and Cr on transformation point of undercooled austenite are compared and analyzed as well as the effects of different transformation temperatures on microstructure transformation of bainite steel are also studied. The experimental results showed that the optimum temperature of microstructure transformation for bainite steel was 330 ℃, which provides theoretical basis for developing production process of bainite steel.
