Ferro Chrome(Ferro Chromium)is an iron alloy whose main components are chromium and iron, and the chromium content is between 50% and 70%. In addition to the main components of chromium and iron, it also contains impurities such as carbon, silicon, sulfur, and phosphorus. Ferro chrome is often used as an important alloy additive in steel smelting and foundry industries.
Classification of Ferro Chrome
According to the different carbon content in ferro chrome, ferrochrome can be divided into four types.
- High-carbon ferrochrome: the carbon content ranges from 4 to 8%;
- Medium carbon ferrochrome: carbon content is between 0.5~4%;
- Low-carbon ferrochrome: carbon content is between 0.15~0.5%;
- Micro-carbon ferrochrome: the carbon content ranges from 0.06 to 0.15%.
Ferro chrome with different carbon content is suitable for different application scenarios.
Ferro chrome containing about 5% carbon content can be used in steelmaking
- Ferro chrome containing about 5% carbon content can be used as a chromium additive for the alloy of steel;
- Ferro chrome with a carbon content of more than 4% is often used to make ball bearing steel and steel for auto parts;
- Ferro chrome with a carbon content of less than 2% is suitable for making stainless steel, acid-resistant steel, and various other low-carbon chromium steels.

Application of Ferro Chromium
Ferro chromium has three functions in the steelmaking and casting industry.
- Deoxidizer. Ferro chromium alloys can remove oxygen from molten steel in the steelmaking process, and other impurities such as sulfur and nitrogen in steel can also be removed with other ferroalloys.
- Alloy additives. According to the composition requirements of the steel type, ferro chromium alloy elements are added to the steel to improve its performance of the steel.
- Inoculant. As inoculant, ferro chromium alloy is added to molten iron before casting to improve the crystalline structure of cast iron.
According to the different carbon content in ferro chromium, it also has different uses. Chromium is mainly used to improve the oxidation resistance and corrosion resistance of steel so that a strongly adhered oxide film is formed on the surface of the steel during the oxidation process, which effectively prevents or slows down the oxidation reaction.
1. High-carbon ferrochrome
High-carbon ferrochrome is usually 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), and can harden steel. Increase the wear resistance and hardness of steel.
2. Medium and low-carbon ferrochrome
Medium and low-carbon ferrochrome is used in the production of medium and low-carbon structural steel, carburizing steel, gears, high-pressure blower blades, valve plates, etc.
3. Micro-carbon ferrochrome
Micro-carbon ferrochrome is mainly used to produce stainless steel, wear-resistant steel, and heat-resistant steel.
Main Factors Affecting Ferro Chrome Price
Ferro chrome is an important alloy raw material for industries such as stainless steel, steel, cast iron, etc. The ferrochrome price has always been of great concern to practitioners in these industries. What are the main factors that affect the ferro chrome price? Let’s start with the production process of ferro chrome.
Ferro chromium is produced by arc carbothermal reduction of chromite. The chromium ore is reduced by coal and coke to form an iron-chromium alloy. The heat of the reduction reaction mainly comes from the arc formed between the tip of the electrode at the bottom of the furnace and the furnace. The environment in which ferrochromium is generated needs to be heated to at least 2800°C. In the smelting process of ferro chrome alloys, power consumption is huge. The lower the carbon content of ferro chrome, the more difficult it is to refining, the higher the power consumption, and the higher the cost. Therefore, the cost of electricity has become the main factor affecting the ferrochrome price.
Because of the low power cost and labor cost in our region, the price of ferro chrome is competitive in the international market. Welcome customers from all over the world to visit our factory.
