Adding chromium to steel can significantly improve the oxidation resistance of steel and increase the corrosion resistance of steel. Chromium is contained in many steels with special physical and chemical properties. The chromium in steel is added with ferrochrome. High carbon ferrochrome is used as an alloying agent for ball steel (0.5% to 1.45% Cr), tool steel, die steel (5% to 12% Cr) and high speed steel (3.8% to 4.4% Cr), which can improve the hardenability of steel and increase the wear resistance and hardness of steel. Adding chromium to cast iron can increase hardness and improve wear resistance. 0.5% to 1.0% chromium can improve its mechanical properties. High carbon ferrochrome and furnace grade ferrochrome are used as furnace materials for smelting stainless steel (AOD or VOD method) in large quantities to reduce production costs. Medium and low carbon ferrochrome is used to produce medium and low carbon structural steel, carburizing steel, and to manufacture gears, high pressure blower blades, valve plates, etc. Micro carbon ferrochrome is used to produce stainless steel, acid-resistant steel, heat-resistant steel and electric heating alloys.
