Low carbon and ultra low carbon silico manganese improve the productivity in the manufacture of stainless steel and special steel by eliminating decarburization in final step. The use of low carbon silico manganese in stainless steels and alloy steels provides a more economical production route, where a combination of manganese and silicon is required in a low carbon steel product.

Ferrosilicon is used as a source of silicon to reduce metals from their oxides and to deoxidize steel and other ferrous alloys. This prevents the loss of carbon from the molten steel (so called blocking the heat); ferro manganese, spiegeleisen, silicides of calcium, and many other materials are used for the same purpose
