Abstract: The continuous cooling transformation (CCT) curves of 36Mn2V steel were obtained on the basis of the expansion curves of continuous cooling at 4 finish rolling temperatures measured on a Gleeble-1500 thermal simulator in combination with metallo-graphic and hardness methods. The experimental results show that with increasing cooling rate the starting temperature of γ/α transformation gradually lowers, but the starting temperature of bainite transformation increases to a plateau and then decreases, and the grains are refined. With the finishing rolling temperature decreasing, the experimental dynamic CCT curves shift to the left and upper wholly, the ferrite along grain boundaries and intra-granular ferrite decrease, and the grains are slightly refined. No bainite appears in the specimen finally rolled at 950 22.
