What is a Mill Scale?

Mill scale is a flaky surface that can be found on iron oxides and metals that have been hot rolled. Mill scale forms on exterior surfaces of sheets and plates as they are being manufactured through rolling steel billets and hot iron into rolling mills.

Mill Scale Beshay Steel

Mill scale is molded on the outer exteriors of billets when they are being manufactured in rolling mills. It is an assortment of iron oxides, regularly, ferric and is dark in color. It is commonly less than 0.1 mm and primarily follows the steel exterior and protects it from environmental erosion to avoid any damage.
