The Root of Mill Scale. Mill scale is also known as iron oxide.It is a hardened surface on hot rolled steel that is formed during the milling process. In his book "Corrosion Prevention by Protective Coatings", Munger explains that the oxide layer coaters typically encounter is formed by the latent heat once the metal has been shaped and is cooling.
