Ferrochrome Chrome

An iron alloy composed of chromium and iron, used as an alloying agent, improves the hardenability of steel and increases the wear resistance and hardness of steel.

Chromium added to steel significantly improves the oxidation resistance of steel and increases its corrosion resistance. Chromium is contained in many steels with special physicochemical properties. Chromium in steel is added with ferrochrome. The addition of chromium to cast iron increases hardness and improves wear resistance, and its mechanical properties can be improved by containing 0.5% to 1.0% chromium.

High-carbon ferrochrome:

Ferrochrome should be lumpy, the internal and its surface of ferrochrome shall not have non-metallic inclusions visible to the naked eye, but when the ingot surface coating is not clean, a small amount of its presence is allowed.

High-carbon ferrochrome is mainly used in the production of stainless steel, of which 200 series stainless steel contains about 16% chromium, 300 series stainless steel contains about 25% chromium, 400 series stainless steel contains about 14% chromium. The largest demand for ferrochrome 300 series stainless steel is also the largest proportion of stainless steel production.

Ferrochrome as an alloying material has the following advantages in the manufacture of steel:

1. Improves corrosion resistance of steel: Chromium in ferrochrome is an important alloying element that significantly improves the corrosion resistance of steel against attacks of oxidation, corrosion and abrasion.

2. Improves the hardness and wear resistance of steel: The chromium in ferrochrome significantly improves the hardness of steel and also improves the physical properties of steel such as wear resistance and tensile strength.

3. Improve the physical and chemical properties of steel: Chromium in ferrochrome is a common alloying element that can significantly improve the physical and chemical properties of steel, such as improving strength, toughness, corrosion resistance, etc.

4. Adjust the organization of steel: The chromium element in ferrochrome can affect the phase transformation and grain size of steel, thus adjusting the organization of steel and optimizing the properties and quality of steel.

5. Reduce production cost: ferrochrome, as an alloy material, can reduce the cost of raw materials and production cost in steel manufacturing.

In conclusion, ferrochrome, as an important alloying material, has a variety of advantages and can effectively improve steel.
