According to the content of carbon,ferrochromium can be categorized to high carbon ferrochromium,
medium carbonferrochromium,low carbon ferrochromium andextra-low carbon ferrochromium.

High Carbon Ferrochromium High carbon ferrochromium can be addition reagent of alloy for ball bearing steel,
tool steel and high-speed steel which has high content of carbon ,in order to improve the characteristics of steel for absolute quenching,abrasion resistance and rgidity.
Medium-Low Ferrochromium Medium and low carbon are used in making medium and low carbon alloy constructional steel to make gear,
vane of high pressure fan and valve.
Extra-Low Carbon Ferrochromium
