Zusammenfassung:•Corrosion domains are established for 410 SS as a function of [HCl] and temperature.•Synergistic effect of hydrogen and chloride ions is found for passive film breakdown.•Permanent uniform degradation of passive film occurs above critical temperature.•Metastable pitting initiates from non-metallic inclusions below critical temperature.•Sigma phase particles are identified in 410 SS by TEM/SAED and remain uncorroded. The corrosion behavior of AISI 410 stainless steel was investigated in relatively dilute HCl solutions with different concentrations and temperature levels. General corrosion occurred at pH
