Electrochemical Properties of Oxide Scale on Steel Exposed
Iron is found in the mill scale since wustite transforms into magnetite and iron. According to the XRD results the hematite sample consisted of approximately 35 hematite. Hematite is formed by oxidation of magnetite which is a relatively slow reaction compared to formation of wustite and magnetite at 850°C.

Mill scale mill scale is a layered and brittle material composed of iron oxides with wustite as a predominant phase. It is normally considered as waste material. From the chemical and physical analysis performed on the mill scale and with respect to the environmental concerns mill scale is considered to be non-dangerous waste and normally considered as a green waste.

Heating of Steel Oxidation and Decarburisation Metallurgy
Oxidation tarnishes the lustre of steel surface of parts and the scale formed is a loss of the precious iron metal thus it is an undesirable (though a natural) process. It is a harmful process when it is necessary to have close tolerance in dimensions of the parts being heat treated. Oxidation reduces the dimensions of the steel parts.

Role of mill scale on corrosion behavior of steel rebars
The steel rebars with and without mill scale were embedded in mortar with about 5.5 mm of the cover thickness (shown in Fig. 2(a)) and the mortar was cured for 28 days in a container kept at room temperature and at 95 RH or higher controlled by using saturated K 2 SO 4 solution. The mortar was produced by mixing water ordinary Portland cement powder and fine aggregates.
