As we all know, ferrochrome is an important alloy additive for steelmaking. And Foosoon’s main supply is low-carbon ferrochrome. So what are the other types of ferrochrome? Let’s take a look!
High Carbon Ferrochrome (HC FeCr):
Composition: High carbon ferrochrome typically contains around 60-75% chromium, 6-8% carbon, and the rest is primarily iron. It has a higher carbon content compared to other types of ferrochrome.
Application: HC FeCr is commonly used in the production of stainless steel, alloy steel, and tool steel.
Medium Carbon Ferrochrome (MC FeCr):
Composition: Medium carbon ferrochrome generally contains 60-65% chromium and 6-8% carbon, along with other elements. It has a carbon content intermediate between high carbon and low carbon ferrochrome.
Application: MC FeCr is used in stainless steel production and other alloy steel applications where a balance between carbon content and other alloying elements is required.
Low Carbon Ferrochrome (LC FeCr):
Composition: Low carbon ferrochrome typically contains 60-70% chromium, with a carbon content kept below 0.10% or even lower. It has a much lower carbon content compared to high carbon ferrochrome.
Application: LC FeCr is widely used in the production of stainless steel, where low carbon levels are crucial to maintaining corrosion resistance.
Charge Chrome (FeCr Charge):
Composition: Charge chrome is a type of high carbon ferrochrome produced from chromite ore and coke. The carbon content is typically high, and it is used as a charge material in the production of stainless steel.
Application: It is used as a source of chromium and carbon in stainless steel production.
Extra Low Carbon Ferrochrome (ELC FeCr):
Composition: Extra low carbon ferrochrome has an extremely low carbon content, usually below 0.03%. It is produced to meet the stringent requirements of certain specialty steel applications.
Application: ELC FeCr is used in applications where very low carbon levels are critical, such as in the production of certain grades of stainless steel.
Ferrosilicon Chrome (FeSiCr):
Composition: Ferrosilicon chrome is an alloy of iron, silicon, and chromium. The chromium content can vary, and it also contains silicon to provide deoxidizing and alloying effects.
Application: It is used as an alloying agent in the production of stainless steel and special alloy steels.
Ferrochrome with a carbon content of less than 2% is suitable for smelting stainless steel, acid-resistant steel and other low-carbon chromium steel. Ferrochrome with a carbon content of more than 4%, commonly used to refine ball bearing steel and steel for automotive parts. Ferrochrome containing about 5% chromium can be used as a chrome agent for alloy transfer iron.
The lower the carbon content of ferrochrome, the more difficult it is to control, and the power consumption is large and the cost is high. The choice of ferrochrome type depends on the specific requirements of the steel or alloy being produced. Different grades offer varying levels of carbon, chromium, and other alloying elements. When buying, choose according to your needs.
