Uses of Ferrochrome:

Ferrochrome is an essential alloy used in various industries. The alloy possesses unique chemical and physical properties that make it suitable for many applications.

Below we discuss in detail the various uses of ferrochrome:

1. Manufacturing of Stainless Steel:

The largest application of ferrochrome is in the production of stainless steel.

Ferrochrome, with its high chromium content, provides the steel with resistance to corrosion and an attractive appearance. The alloy enhances the steel’s strength by resisting high-temperature creep, pitting, and scaling.

High-carbon ferrochrome is added to carbon steel to improve its durability and toughness. 2.

Adding Chromium to Carbon Steel:

High-carbon ferrochrome is used extensively to produce chromium-containing carbon steels. These steels have unique properties such as improved machinability, wear resistance, and toughness.

The addition of ferrochrome to carbon steel also improves its response to heat treatment, making it ideal for use in forging, machine tool components, and engine parts. 3.

Manufacturing of Ball-Bearing Steels, Tool Steels, and Alloy Steels:

Ferrochrome is also used in the production of high-quality ball-bearing steels, alloy steels, and tool steels. These steels require high-strength properties, and the addition of ferrochrome enhances their hardness, resistance to wear and corrosion, and ability to retain their structure under high temperatures.

High-carbon ferrochrome is commonly used to produce these steels. 4.

Acid-Resistant Steels:

Low-carbon ferrochrome is used in the production of acid-resistant steels. The addition of low-carbon ferrochrome reduces the nitrogen content that contributes to steel’s sensitivity to acid corrosion.

Low-carbon ferrochrome improves the steel’s ability to resist acid corrosion by reducing the nitrogen content and forming stable chromium oxide (Cr2O3) on the steels surface. This oxide layer acts as a barrier between the steel and corrosive substances.

5. High-Chromium Cast Steels:

High-nitrogen ferrochrome is used to produce high-chromium cast steels.

The grain structure in these steels is enhanced by the addition of high-nitrogen ferrochrome, which results in an increase in grain refinement and a corresponding increase in strength. The addition of high-nitrogen ferrochrome to cast steels also enhances its ability to resist wear, corrosion, and erosion.

6. Cast Irons and Powder Metallurgy:

Foundry-grade ferrochrome is used in the production of cast irons and powder metallurgy.

The alloy enhances the iron’s ability to resist high temperatures and provides it with a high degree of wear resistance. The addition of ferrochrome also improves the iron’s hardness, strength, and wear resistance, making it suitable for use in various applications.

7. Ferrochrome Slag and Refractory Materials:

Ferrochrome slag is used in the production of refractory materials, which are used in civil engineering applications.

Ferrochrome slag is an ideal material for producing refractory materials due to its high melting point, excellent thermal shock resistance, and low thermal conductivity. A suitable combination of ferrochrome slag and other additives produces refractory materials used in blast furnaces, furnaces, and other high-temperature environments.

8. Ferrochrome Lignosulfonate:

Ferrochrome lignosulfonate is used as a fluid loss reducer in water-based drilling mud systems.

The product is used to control the fluidity of the drilling mud by maintaining its viscosity at different temperatures and pressures. It acts as a stabilizer that prevents the formation of mud cakes by minimizing clay contaminants and improving the mud’s lubrication and filtration properties.
