~We are offering ferro silicon etc. We have our own factory of ferro silicon products,
the features and specifications for ferro silicon are as below:
1. Features:
the appearance of ferro silicon is the grey lumpish solid. It has very strong stabilities and does not place any chemical reaction in the dry air.
2. Application:
ferrosilicon is often used as deoxidizer in steel- making.it is also used extensively in low alloy steel, non-ferrous metal, bearing steel, heat-resistant steels and electrician silicon-steel.
