Cover: Three types of oxide inclusions are contained in the steel. Al‐Si‐Ca‐O and Al‐Mg‐Si‐Ca‐O inclusions are more electrochemically active than the steel, and pitting corrosion occurs on both inclusions. α phase has a higher electrochemical activity and a lower corrosion resistance than γ phase. Pitting corrosion is more likely to occur at the inclusion/α phase interface, rather than the inclusion/γ phase interface.
