Ferrochrome

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.
