Low-carbon Silicomanganese
Products Description
Supplied as silvery-grey metallic lumps, refined in submerged-arc furnaces using high-grade, low-phosphorus manganese ore. When producing stainless steel, special carbon steel, and motor-lamination grades that require extremely low endpoint carbon, LCSiMn replaces high-carbon ferromanganese to eliminate the final decarburization step - substantially improving productivity.

Products Advantage
1.Ultra-low carbon (C≤0.10%) adds virtually no carbon in stainless/special steel routes - eliminates final decarburization.
2.Low P & S (P≤0.10%, S≤0.05%) dramatically improves steel cleanliness.
3.Replaces HCFeMn in medium/low-carbon FeMn production - 4–6% productivity gain, less Mn oxidation loss.
4.Si≥27% delivers strong deoxidation, reducing total deoxidizer consumption.
5.Standard 10–70mm lumps, or customized sizing per customer spec.
