Desulfurization of steel [SubsTech]

31/5/2012· Sulfur (S) may dissolve in liquid iron (Fe) at any concentration.However solubility of sulfur in solid iron is limited: 0.002% in α-iron at room temperature and 0.013% in γ-iron at 1832 F (1000 C). When a liquid steel cools down and solidifies the solubility of sulfur drops and it is liberated from the solution in form of iron sulfide (FeS) forming an eutectic with the surrounding iron.
