According to the microstructure of EH40 marine steel plate. The microstructure is mainly ferrite and pearlite, and the grain deforms along the rolling direction and presents obvious banded structure. EH40 marine steel plate is hypoeutectoid steel, which can prevent the coarse austenite grain size by controlling the rolling temperature, so as to increase the probability of nucleation during austenite crystallization.
The austenite recrystallized grain was refined again and the strength and toughness of EH40 marine steel plate alloy were improved by rolling. EH40 marine steel plate with large deformation for several times in two-phase zone. The microstructure grain size distribution was calculated by metallographic analysis software. Among them, about 63% of the grain size is below 10 µm, indicating that the grain size of low-temperature steel of EH40 marine steel plate has been well refined.
