Mill scale is a thin, flaky layer of iron oxide that forms on the surface of hotrolled steel. It is used as a protective coating during storage and transport to prevent corrosion of the underlying steel. When welding, the mill scale must be removed from the surface of the metal to ensure a strong bond between the two pieces.

Mill scale is a mixture of iron oxides and other impurities formed in high temperatures. Rust is also a mixture of iron oxides but is created in the presence of moisture in everyday temperatures. For the same thickness, rust is far easier to remove than fresh scale. If scale is old, dry, and rusty, it is almost as easy to remove.

If plates are painted without the removal of mill scale, the adhesion of paint is insufficient. As a result, with time when the mill scale scrapes off the plate surface, the paint falls off along with it, exposing the steel plate to sea environment which will result in corrosion. Presence of mill scale contaminates the weld, reducing weld quality.
