Mill scale consists primarily of magnetite, Fe3O4, of characteristic blue-gray "steely" color. An extremely thin outer film of hematite, Fe2O3, is invisible to the naked eye. The inner portion of the magnetite contains fine metal grains and sometimes, residual black FeO, which contribute to the roughness of descaled metal.

The melting point of mill scale is around 1370 deg C and the boiling point is around 2760 deg C. It has a stable state. It is insoluble in water and alkalis but soluble in most of the strong acids. It is normally classified as non-dangerous waste material. Mill scale particles, flakes, and chips are brittle and have low mechanical strength.

The amount of slag produced during the steelmaking process directly relates to the iron content of the feedstock. Higher iron content equates to less slag. The iron content of direct shipping haematite iron ore is typically 58% to 64%. High grade iron ore concentrate contains 65% to 70% iron. Slag stockpiled alongside a steel mill in China.
