This paper presents a study on bending corrosion fatigue behavior of suspension leaf spring steels SUP9 (Japanese Industrial Standard) and SUP10M with different surface conditions. The reduction in fatigue strength of these steels with ultimate tensile strength in the range from 1400 to 1800 MPa by 3 percent NaCl aqueous solution was 74 and 92 percent, respectively. The shot peening effect on corrosion fatigue strength was relatively remarkable, while, the influence of surface roughness on corrosion fatigue strength was slight. Corrosion pits were observed at crack initiation area and striation was predominant at crack propagation area in 3 percent NaCl aqueous solution. It may be concluded that a sharp decrease of corrosion fatigue strength of these high strength steels in corrosive environment containing C1- is mainly due to corrosion pit formation at the initiation area of the corrosion fatigue fracture surface.
