Abstract The accelerated corrosion tests were carried out to investigate the effect of the microstructure on the corrosion resistance on bainitic steel. The corrosion resistance was better for bainitic steel than annealing sample based on weight loss. The mechanism of the rust products formed has been investigated by SEM and XRD. The rust layers were composed of the inner rust layer and the outer rust layer on two samples of steel. The rust layers were mainly composed of ��-FeOOH and ��-FeOOH. The homogeneous microstructure was beneficial to enhance the corrosion resistance.
