Ferro Sulphur

Ferro Sulphur, composed of iron and sulphur with a sulphur content ranging between 28% and 32%, with this content being what defines the quality of the product. There are typically two grades according to its sulphur content, between 28% and 32% and between 48% and 50%.
 
Ferro Sulphur is used in metallurgy give the steel or alloy the desired sulphur content. It is used for this purpose instead of elemental sulphur because the low melting point of the sulphur could accumulate on the molten metal surface, causing SO2 emissions and also a deterioration of its mechanical properties by the formation of a low eutectic melting point in the grain boundaries.
