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. ...
