Corrosion fatigue damage and its electrochemical characteristics of high purity ferritic stainless steel (Fe‐26Cr‐1Mo) under symmetrical tension compression strain control have been investigated in 1M H 2 SO 4 3.5 % NaCl solution by using three‐electrode technique at imposed passive potential. The tests were carried out the total amplitudes × 10 −3 , 8 1.0 −2 1.2 . effects amplitude on dissolution plastic deformation surface studied particularly. At low (Δε t = ), passivity‐maintaining current was small stable because slip activity. maximum tensile half cycle, l p always bigger than c or sometimes equal to compressive cycle NaCl. enhanced induced increasing dissolution. anodic reflects breakdown film, only one peak occurs within cycle. intermediate behaviour very after cyclic hardening 3.5%, NaCl, but periodical jumpings during cycling observed saturation region 1 M
