Ferro Chrome Meaning
Ferrochrome alloy is mainly composed of chromium, iron, carbon, and other impurities such as silicon, phosphorus, sulfur, etc. It is used as an alloying agent, can improve the hardenability of steel, and increase the wear resistance, and hardness of steel.
Ferrochrome Classification
Ferrochrome is an iron alloy composed of chromium and iron, which is an important alloy additive in steelmaking. Ferrochromium is divided into high carbon ferrochromium (containing 4~8% carbon), medium carbon ferrochromium (containing 0.5~4% carbon), low carbon ferrochromium (containing 0.15~0.50% carbon), micro carbon ferrochromium (containing 0.06% carbon), ultra-micro carbon ferrochromium (containing less than 0.03% carbon). Chromium alloys also include silicon chrome, ferrochrome nitride, etc.
Ferrochrome Uses
The addition of chromium can significantly improve the oxidation resistance and corrosion resistance of steel. Chromium is found in many steels with special physical and chemical properties. Chromium in steel is added with ferrochrome. The hardness and wear resistance of cast iron can be improved by adding chromium, and the mechanical properties can be improved by containing 0.5% ~ 1.0% chromium.
The Main Uses and Specification of High Carbon Ferrochrome
- Used as an alloying agent for ball steel, tool steel, and high-speed steel with higher carbon content, to improve the hardenability of steel, and increase the wear resistance and hardness of steel.
- Used as an additive to cast iron, improve the wear resistance and hardness of cast iron, and improve the heat resistance of cast iron.
- Used as chromium-containing raw material for the production of a silicon chromium alloy, medium, low, and micro carbon Ferro chrome by the slag-free method.
- Used as chromium-containing raw material for electrolysis production of chromium metal.
- Used as raw material for smelting stainless steel by oxygen blowing method.

The Uses and Specifications of Nitrided Ferro Chrome
Nitrided Ferro chrome, also known as nitrogen-containing low-carbon Ferro chrome. It is widely used in stainless steel, heat-resistant steel, corrosion-resistant steel, alloy steel, and other special steel production. According to the research of ZXferroalloy, nitrogen expansion of austenite zone is about 30 times that of nickel, can partially replace the precious metal nickel, and reduce production cost.
