Sulfidation of pure metals - a short review

6 Temperature dependence of sulfidation and oxidation rates of several metals. 

It is very important to note that the sulfur solubility in metals is much lower than in the case of oxygen. The very small solubility of sulfur in metals as well as rapid scale formation make the formation of an internal sulfidation zone, which plays an important role in oxide corrosion, impossible.
