Abstract In order to study the phase transformation of P280GH steel nuclear power tube during cooling process after hot-roll process, the CCT and TTT transformation kinetics curves were measured by using physical simulation method. The results show that coarse ferrite and pearlite form at low cooling rates and the low-temperature microstructure phase can be reduced by increasing the cooling rate. When the cooling rate is more than 10 ℃/s, bainite begins to appear. Based on the superposition principle, the numerical model of the cooling process of the test steel is established by using the finite element method. The temperature field and the evolution of phase transformation along the direction of the wall thickness of the P280GH steel specimen with dimensions of [?219.1 mm]×18.26 mm were analyzed for air cooling and water cooling, respectively. The results show that the microstructure under air cooling condition is homogeneous pearlite, and there is no bainite and retained austenite. The microstructure under water cooling condition is martensite, and the difference between the internal surface and the external surface was 3.6%, which is basically consistent with that of the actual heat treatment. The research results can provide guidance for the cooling process of hot rolling P280GH steel pipe production.
