•The initial stages of the pitting corrosion of Q460NH steel in a marine environment was studied.•Two different types of inclusions formed in the Q460NH steel after adding rare earth.•Both types of inclusions showed a lower Volta potential than the matrix.•Pitting corrosion was induced by the dissol...
