Mill Scale
Mill scale coatings are generally found on regular mild steel. This is the most common and affordable type of steel on the market. Cold rolled steel is a more expensive product, and it does have a light scale coating. However, it is nowhere near as thick as the scale on mild steel. Since it isn't rolled out using heat, the coating that is ...

What is Mill Scale and How to Remove It
Mill scale (also called scale) is the flaky surface that forms on hot-rolled steel. Its composition includes FeO (iron (II) oxide), Fe2O3 (iron (III) oxide), and Fe3O4 (iron (II,III) oxide). You will find mill scaling on steel sheets, plates, and profiles. It arises when you roll hot steel billets or iron in rolling mills.
