High-Carbon Ferro Chrome for Ball Bearing Steel
Ferro chromium is an iron alloy composed of chromium and iron. It is an important alloy additive for steelmaking.
According to different carbon content, ferro chrome can be divided into high-carbon ferrochrome (10% C content), low-carbon ferrochrome (0.25% C content), Micro-carbon ferrochrome (0.03%-0.15% C content).
The lower the carbon content of ferrochrome, the more difficult it is to smelt, the higher the power consumption, and the higher the cost. Ferrochrome with a carbon content of less than 2% is suitable for smelting stainless steel, acid-resistant steel and other low-carbon chromium steels. Ferrochrome with a carbon content of more than 4% is commonly used to make ball bearing steel and steel for auto parts.

Product Applications
1.The addition of chromium to steel can significantly improve the oxidation resistance of steel and increase the corrosion resistance of steel. 2.Chromium is contained in many steels with special physical and chemical properties.
3.Chromium in steel is added with ferrochromium. High carbon ferrochromium is used as alloying agent for ball steel (0.5%～1.45%Cr), tool steel, die steel (5%～12%Cr) and high speed steel (3.8%～4.4%Cr), which can improve the quenching of steel. permeability, increase the wear resistance and hardness of steel. Adding chromium to cast iron can increase hardness and improve wear resistance, and 0.5% to 1.0% chromium content can improve its mechanical properties.
4.High carbon ferrochromium and charge grade ferrochromium are used in large quantities as the charge for smelting stainless steel (AOD or VOD method) to reduce production costs.
5.Medium and low carbon ferrochrome is used in the production of medium and low carbon structural steel, carburized steel, gears, high pressure blower blades, valve plates, etc. Micro-carbon ferrochromium is used in the production of stainless steel, acid-resistant steel, heat-resistant steel and electrothermal alloys.
