The atmospheric corrosion behaviour of 30CrMnSiA high-strength steel exposed in rural, industrial and marine atmosphere environments in China for 60 months was investigated in virtue of the weight loss, X-ray diffractometer (XRD), scanning electron microscope (SEM) and grey relational analysis. The results showed that 30CrMnSiA high-strength steel exhibited the highest corrosion susceptibility and the lowest corrosion susceptibility in marine atmosphere environment and rural atmosphere environment, respectively. Lepidocrocite and goethite were found as the major constituents of the rust layer in three types of atmosphere environments, and akaganeite was also detected in marine atmosphere environment. The rust layer exhibited the tendency of flaking away from the substrate and becoming dense in marine atmosphere environment and rural atmosphere environment, respectively. Grey relational analysis demonstrated that, among a variety of environmental factors, the airborne sea-salt was the primary factor influencing the atmospheric corrosion of 30CrMnSiA high-strength steel.
