Main Applications
1. Steelmaking Deoxidizer & Alloying Agent
FeSi45 lumps are mainly used in carbon steel and low-alloy steel production.They effectively remove oxygen from molten steel, improve steel strength, hardness, and corrosion resistance.
2. Foundry Inoculant
Our FeSi45 lumps can be crushed into smaller particles for inoculation in gray iron and ductile iron casting, helping to refine graphite structure and reduce casting defects.
