High Carbon Silicon Alloys for Steelmaking & Foundry

High carbon silicon alloy (also known as silicon carbon alloy) is a deoxidizer and carburizer containing approximately 60-68% Si and 15-20% C. Unlike standard ferro silicon, it provides both silicon and carbon, making it cost-effective for steel deoxidation and alloying. It is widely used in ladle furnaces and induction furnaces.

The choice depends on your target carbon and silicon levels. For balanced deoxidation and carburization, our Si60 C15 grade is popular. For higher silicon efficiency, consider Si65 C15. For maximum carbon, Si68 C18 offers high C content. For powder injection processes, Si40 C20 powder is recommended. Contact our engineers for a free consultation.

High carbon silicon alloy is used in steelmaking for deoxidation, carburization, and alloying. It replaces part of the need for ferro silicon and carbon additives, reducing costs. It is suitable for carbon and low-alloy steel production, foundry iron inoculation improvement, and ladle refining. See our full product line for more options.
