Products Description
Ferrochrome (FeCr) is a ferroalloy composed of chromium and iron. It is an important alloy agent in steelmaking. According to different carbon content, Ferrochrome is divided into High Carbon Ferrochrome (carbon content of 4~8%), Medium Carbon Ferrochrome (carbon content of 0.5~4%), Low Carbon Ferrochrome or lc ferro chrome (carbon content of 0.15~0.50%), Micro Carbon Ferrochrome (with a carbon content of 0.06%), Ultra-Fine Carbon Ferrochrome (with a carbon content of less than 0.03%), as well as silicon-chromium alloy, nitride ferrochromium, etc.

Classification of Ferrochrome
Ferrochromium is a ferroalloy with chromium and iron as the main components. It is one of the main alloying agents used in the iron and steel industry. In addition to the main components of chromium and iron, it also contains impurities such as carbon, silicon, sulfur, and phosphorus.
FeCr contains 55% to 75% chromium and is divided into high carbon (4% to 10% C), medium carbon (0.5% to 4% C), low carbon (>0.15% to 0.5% C), and low carbon (>0.15% to 0.5% C) according to the carbon content. Micro-carbon (≤0.15%C) FeCr metal.
Ferrochrome high carbon is also called carbon ferrochrome, and medium, low, and micro-carbon ferrochrome alloy is also called refined ferrochromium. High-carbon ferrochrome produced from chrome ore with a low chromium-to-iron ratio, containing 50% to 55% of Cr is called charge-grade ferrochrome alloy, and nitrogen-containing ferrochromium containing N2% to 10% is used as a nitrogen alloying agent.
Application of FeCr
The addition of chromium to steel can significantly improve the oxidation resistance of steel and increase the corrosion resistance of steel. Chromium is contained in many sheets of steel with special physical and chemical properties. Chromium in steel is added with ferrochromium.
High carbon ferrochrome is used as an 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 chromium content of 0.5% to 1.0% can improve its mechanical properties. High carbon FeCr alloy and charge grade ferrochromium is used in large quantities as the charge for smelting stainless steel (AOD or VOD method) to reduce production costs.
Medium and ferro chrome low carbon is used in the production of medium and low-carbon structural steel, carburized steel, gears, high-pressure blower blades, valve plates, etc.
Micro-carbon ferrochrome is used in the production of stainless steel, acid-resistant steel, heat-resistant steel, and electrothermal alloys.
