To obtain satisfactory performance from a paint system it is essential for millscale to be removed from the surface of the steel. Not only does it contribute directly to corrosion, but it will eventually become detached from the steel surface and is therefore an unsatisfactory substrate for painting.

This happens at low temperatures of heating (≈ 650 C). But usually, the rate of decarburisation is higher than the rate of oxidation. The surface layer of steel beneath the scale loses its carbon, causing decarburisation and the surface may show only ferrite grains. Decarburisation is normally a harmful phenomenon.
