Introduction to Low Carbon Ferrochrome

Low carbon ferrochrome is an iron alloy, mainly composed of chromium (Cr) and iron (Fe), while containing a low content of carbon (C) (usually C ≤ 0.1%). It is an important alloy additive in the metallurgical industry, a key raw material for smelting stainless steel, speciality steel and corrosion resistant alloys, and is particularly suitable for the production of steel that is sensitive to carbon content.

Compared with high carbon ferrochrome, low carbon ferrochrome's can reduce the carbon content in stainless steel, avoid intergranular corrosion and improve corrosion resistance. At the same time, the use of low carbon ferrochrome may simplify the smelting process by eliminating the need for additional decarburisation steps, saving you money and time.

Low carbon ferrochrome is our advantageous product, we choose high quality raw materials for our low carbon ferrochrome, and improve the production process at the same time. We ensure large-scale production capacity and high quality products.

Chemical composition：

Chromium (Cr): The content is usually 60%-70%, which is the core alloying element and gives the material anti-oxidation and corrosion resistance.
Carbon (C): Strictly controlled at 0.03%-0.15%, significantly lower than high carbon ferrochrome (6%-8%), to avoid embrittlement of steel.
Impurity elements: Silicon (Si≤1.5%), phosphorus (P≤0.03%), sulfur (S≤0.03%) and other contents are extremely low to ensure the purity of the alloy.

Physical properties：

Melting point: about 1550-1600°C, high compatibility with molten steel, easy to smelt.
Density: 6.8-7.2 g/cm³, high density helps the alloy sink quickly into the molten steel.
Form: mostly in block (10-50mm) or powder, easy to add accurately.

Low Carbon Ferro Chrome Size

Ferro Chrome block

The melting rate of block ferrochrome in the high-temperature furnace is slow, which can maintain a stable smelting process. It is suitable for large-scale steelmaking.

Ferro Chrome granular

The particle size of ferrochrome makes the alloy composition evenly distributed in the high-temperature furnace, which is suitable for the refining stage.

Ferro Chrome powder

Powdered ferrochrome can dissolve quickly at high temperatures, improve alloying efficiency, and is suitable for fine processing.

Application of Lc Ferro Chrome

Stainless steel production

Uses:Low carbon ferrochrome is an important alloying additive for the production of stainless steel, especially for the smelting of low carbon stainless steels such as 304, 316, 321, etc.
