Mill scale is formed on the outer surface of plates, rolls, sheets or profiles when iron and steel are heated for rolling, forging, or other processing. Being produced during the reheating, conditioning and hot rolling operation, mill scale initially adheres to the steel surface and protects it from atmospheric corrosion, provided no break occurs

What exactly is Mill Scale and what is done about it

Mill scale is found on all hot-rolled steel products unless processed in a protective atmosphere or descaled (e.g., for galvanizing). At hot rolling temperatures, an inner layer of wüstite, FeO, exists between the steel and magnetite.

What exactly is Mill Scale and what is done about it

2005. A. Mill scale consists primarily of magnetite, Fe 3 O 4, of characteristic blue-gray "steely" color. An extremely thin outer film of hematite, Fe 2 O 3, is invisible to the naked eye. The inner portion of the magnetite contains fine metal grains and sometimes, residual black FeO (see below), which contribute to the roughness of descaled metal.
