Mill scale - Wikipedia
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.

WHAT IS MILL SCALE? - Dulux Protective Coatings
WHAT IS MILL SCALE? Mill scale is often present on raw steel and is frequently mistaken for a blue-coloured primer. Mill scale is a type of iron oxide that is formed on the surface of the steel during the hot-rolling process. The very high surface temperature combined with high roller pressures result in a smooth, bluish grey surface.

What is Hot Rolling? - Definition from Corrosionpedia
Agriculture equipment; Metal buildings; Guard rails; Surface defects may occur due to scale, rust or impurities. Scale is produced when the hot surface is oxidized by air. This mill scale can reduce corrosion if steel is exposed to air over short periods, however, the corrosion increases if exposed for long periods.
What is a Mill Scale? - Definition from Corrosionpedia
Electrochemically, mill scale is cathodic compared to steel, so any kind of breakage in the scale could lead to accelerated corrosion in the steel at the point of breakage. Thus, the scale is considered an advantage for a short time until the coating cracks due to mechanical factors such as the handling of steel as well as other processes such ...
