Ferro Silicon



Ferro Silicon

We are industry leading manufacture and producer of Ferro Silicon. It is seen that stainless sector is one of the fastest growing categories in the steel industry and thus Ferro Silicon comes into the picture. Stainless steel requires Ferro Silico compared to regular carbon steel.

It is mainly used in the manufacture of steel and cast iron and produce fine quality steel. Ferro Silicon is used to remove oxygen from steel for better quality and durability. Our clients also use Ferro Silicon to manufacture pre-alloys like Magnesium Ferro Silicon (FeSiMg). It is used to modify melted malleable iron.

Uses of Ferro Silicon

Ferro Silicon is made available in different composition as per the requirements of the clients. It may be low Al, High Purity or low C Ferro Silicon.

It is used in the production of special steel qualities and better durability.

Our special grades of Ferro Silicon help to keep both the content of inclusions and the carbon content in the final steel at low levels.

Ferro Silicon is used as raw material high-purity quartz, charcoal and iron ore in the production of arc furnaces.
