Ferrochrome is used in the making of special types of steel, more
extensively used for stainless steel is an alloy of iron and chromium.
It is divided into two main types according to the carbon contents of
the products i.e. High Carbon Ferrochrome (HCFC) and Low Carbon
Ferrochrome (LCFC).
Chromium is added as ferrochrome in various types of steel to increase hardening, wire resistance to corrosion and stability at high operating temperatures. Its corrosion resistant properties become very much marked when the chromium content exceeds 12% in low carbon steels. Since addition of other elements such as nickel, increase resistance to non oxidizing acids, improves ductility and gives cold working properties. This is essential for the production of stainless steel and cast iron. Consumption of charge chrome or HCFC has been fairly successful although the demand for LCFC is going down not only in the country but also throughout the world.
so, plzzzzz thanks for my answer.
