Electrolytic manganese metal is a carbon-free Mn unit produced by electrowinning, deposited as brittle cathode flakes at Mn ≥ 99.7%. Because manganese enters liquid steel as a near-pure element rather than as an Fe-Mn alloy, it raises the Mn target without dragging in carbon — the C ≤ 0.03% ceiling lets metallurgists hit Mn aim in grades where high-carbon ferromanganese would breach the carbon or phosphorus spec. Manganese supplements deoxidation and fixes residual sulfur as MnS, displacing low-melting FeS films that cause hot-shortness, so castability and hot ductility improve. As an austenite stabilizer it also strengthens work-hardening response.
Primary uses: stainless steel, special and low-C alloy steels, aluminum alloy additions, and battery-grade MnSO₄ feedstock. Additions are typically dosed from tenths of a percent up to a few wt% against ladle analysis. Low Si ≤ 0.01%, Se ≤ 0.02%, S ≤ 0.05%, and Fe ≤ 0.2% keep residuals controlled for clean-steel and chemical routes.
Supplied with COA and MTC, multi-regional sourcing, CIF Marmara or Gebze bonded stock, 20 MT FCL / 5 MT LCL. Send grade and tonnage for an RFQ.

Häufig gestellte Fragen
When should I specify electrolytic manganese metal instead of high-carbon or medium-carbon ferromanganese?
Choose electrolytic Mn flakes when your steel grade caps carbon and phosphorus tightly — austenitic stainless, low-C alloy steels, and special steels. At Mn ≥ 99.7% with C ≤ 0.03% and Si ≤ 0.01%, it adds Mn units without the carbon load of HC FeMn (C up to ~7%) or the residuals in lower-purity ferroalloys. For high-C grades where carbon is acceptable, ferromanganese is the more economical Mn source.
What addition rate should I plan for in stainless and special-steel melts?
Dosage is driven by your target Mn residual, incoming bath Mn, and recovery, not by a fixed rate. Calculate the Mn gap to your aim chemistry, then divide by expected recovery — flake addition into a deoxidized bath typically recovers well, but EAF versus induction practice, slag chemistry, and timing all shift yield. Add late and after deoxidation to limit Mn loss to slag. Run a trial heat to confirm recovery on your furnace before locking a standard.
How is it packaged, and what are typical MOQ and lead time?
Flakes ship in sealed bags on pallets, commonly around 1 MT per unit, kept dry to limit surface oxidation. Order sizes scale to 20 MT FCL or 5 MT LCL, with Gebze bonded stock available for faster Marmara-region pulls. Lead time depends on whether material is drawn from local bonded stock or replenished through multi-regional sourcing; share your grade, tonnage, and delivery term (CIF Marmara, ex-bonded) and we will confirm a date against current position.
What quality documentation and testing come with each lot?
Each lot ships with a COA / MTC stating Mn and the controlled residuals — C, S, Se, Si, Fe — against the grade limits. Manganese and impurities are determined by standard wet-chemistry and instrumental methods (e.g. ICP/combustion for C and S). If you need sampling per a specific ISO or ASTM protocol, third-party witness analysis, or element thresholds tighter than the standard COA, specify that at the order stage so testing scope is set before shipment.
What are the alternatives if electrolytic manganese metal is over-spec or unavailable for my grade?
For grades that tolerate carbon, medium-carbon or low-carbon ferromanganese delivers Mn units at lower cost, with C and Si chosen to fit your ladle window. Where only ultra-low carbon works, electrolytic metal or refined low-C FeMn remain the route. For non-metallurgical demand, the same Mn ≥ 99.7% flake feeds battery-grade MnSO₄ production. Send your aim chemistry and carbon ceiling and we will map the most cost-effective Mn source from multi-regional sourcing.
