High carbon ferrochrome

Ferrochrome is an iron alloy composed of chromium and iron. It is an important alloy additive in steelmaking. High carbon ferrochrome is made from chromite and silicon as slag flux. It is a solid solution of chromium, iron and carbon, a complex compound of chromium, iron and carbon.This product is one of the most common ferroalloys and has the characteristics of high strength, corrosion resistance, wear resistance, high temperature resistance and oxidation resistance.

Specifications: 0-10mm, 10-50mm, 10-100mm or customized according to customer requirements.

APPLICATION

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 steels with special physical and chemical properties. 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. 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. Medium and low carbon ferrochromium 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.
