Corrosion of steel reinforcement bars in concrete – IspatGuru

The last defense against corrosion is offered by the blue oxide film (mill scale) around the surface of the rebar. This oxide film prevents corrosive agents from coming into direct contact with the bare metal. Thus mill scale provides localized corrosion protection. However, as time passes the above conditions tend to alter.

Wikizero - Mill scale

Mill scale, often shortened to just scale, is the flaky surface of hot rolled steel, consisting of the mixed iron oxides iron(II) oxide (FeO), iron(III) oxide (Fe 2 O 3), and iron(II,III) oxide (Fe 3 O 4, magnetite).. Mill scale is formed on the outer surfaces of plates, sheets or profiles when they are being produced by rolling red hot iron or steel billets in rolling mills.
