Product Introduction
Low Carbon Ferro Manganese (LC FeMn) is a refined master alloy engineered for clean steelmaking to supply high-concentration manganese without adding unwanted carbon.
Product Features
Low Carbon Addition Keeps carbon levels strictly under C <= 0.5% - 1.5%, allowing large manganese additions without breaching carbon limits in clean steel.
High Density & Fast Dissolution High-density lumps drop through the slag layer directly into liquid steel, achieving over 90% manganese recovery.
Active Deoxidation & Desulfurization Reacts with oxygen and sulfur to form light inclusions that float out cleanly, reducing impurities in the final melt.
Strict Impurity Control Limits phosphorus (P <= 0.2%) and sulfur (S <= 0.02%) to prevent hot cracking and improve steel toughness.

Custom Production & Dispatch Protocol
Chemical & Granularity Target Alignment
Buyer provides exact chemistry thresholds (Mn, C, P, S), physical particle distribution, and discharge handling specs.
Trial Smelting & Spectrometric Validation
A sample batch is refined in an electric furnace and tested via lab spectrometers to confirm elemental targets prior to full production.
Sizing Processing & Dust Removal
Continuous jaw crushing paired with vibratory screening to achieve the target grain size while pneumatically extracting fine dust.
Weather-Sealed Bagging & Batch Tagging
Final alloy is sealed in moisture-proof liners with dedicated batch tracking numbers for immediate port unloading and furnace charging.
Protective Packaging & Transit Safeguards
Double-Layer Moisture Barrier
Packed in heavy-duty 1000 kg woven Jumbo Bags lined with a thick polyethylene inner bag to prevent air exposure and oxidation.
High-Density Storage Palletizing

FAQ
Q: Why use Low Carbon Ferro Manganese over High Carbon Ferro Manganese?
A: High Carbon FeMn increases total carbon in liquid steel. Low Carbon FeMn allows high-volume manganese additions without exceeding carbon limits in clean steel grades.
Q: What are the standard sizing options for bulk orders?
A: Standard physical forms include 10-50 mm lumps, 10-100 mm lumps, and 1-3 mm / 3-8 mm granules. Custom size ranges are processed upon request.
Q: How is fine dust controlled during production and packaging?
A: All crushed material passes through vibratory screeners with pneumatic dust extractors, keeping fine particles (< 10 mm) below 5%.
Q: What size range is recommended for automated ladle feeding systems?
A: Screened 10-30 mm or 10-50 mm lumps are recommended to prevent chute jamming and ensure consistent mass-flow rates.
Q: What is the minimum order quantity (MOQ) and lead time for custom chemical grades?
A: The MOQ for custom alloy ratios or non-standard particle sizing is 20 Metric Tons. Standard custom production lead time is 12 to 15 days.
Q: How does moisture affect Low Carbon Ferro Manganese during storage?
A: Exposure to moisture can cause surface oxidation and fine degradation. Keeping bags sealed in dry indoor storage preserves physical and chemical properties indefinitely.
Q: What is the typical lead time for a standard 20ft container order?
A: Standard chemical grades and sizing ranges ship within 10 to 14 days after specification confirmation. Custom sizing or specialized chemical ratios take 14 to 18 days.
