High Carbon Ferro Manganese – Product Overview
High Carbon Ferro Manganese (HCFeMn) is an essential alloy in steelmaking, produced by carbothermic reduction of manganese oxide ores in submerged arc furnaces. Our Mn65-C7.0 grade offers a minimum of 65% manganese with controlled carbon content (≤7.0%), providing an optimal balance for most carbon steel applications. It serves as a powerful deoxidizer, sulfur remover, and alloying element that improves strength, toughness, and hardness of steel.
Product Core Advantages
- Consistent Manganese Content: Minimum 65% Mn with tightly controlled impurities (Si, P, S) for reliable metallurgical performance.
- Versatile Application: Suitable for carbon steels, low-alloy steels, stainless steels, and cast irons.
- Custom Sizing: Available in lumps, granules, or powder to match your furnace charging or injection requirements.
- Cost-Effective: High carbon grade offers the most economical manganese addition for bulk steel production.
- Stable Supply: Produced from high-grade manganese ores with strict quality control from raw material to finished product.
Typical Application Areas
High Carbon Ferro Manganese is vital in many metallurgical processes:
- Steel Deoxidation: Manganese combines with oxygen and sulfur to form MnO and MnS inclusions, preventing hot shortness and improving workability.
- Alloying Element: Increases strength, hardness, and wear resistance in structural steels, rail steels, and Hadfield manganese steels (10-14% Mn).
- Cast Iron: Added to gray and ductile iron to control carbide formation and increase tensile strength.
- Welding Electrodes: Used as a coating component to stabilize the arc and improve weld metal properties.
- Foundry Industry: Essential for producing manganese-alloyed castings and ingots.

Application Guidelines – High Carbon Ferro Manganese Mn65-C7.0
High Carbon Ferro Manganese (HCFeMn) is a versatile material with the following primary applications:
Steel Deoxidation & Desulfurization
Added to molten steel in the ladle or furnace (typically 5-15 kg per ton) to combine with dissolved oxygen and sulfur, forming oxides and sulfides that float out, improving steel cleanliness and reducing hot shortness. Mn65-C7.0 provides a cost-effective source of manganese for this purpose.
Alloying in Carbon & Low-Alloy Steels
Manganese increases hardenability, tensile strength, and wear resistance. Common in A36, 1045, 4140, and rail steels. Addition rates range from 0.5% to 2% Mn depending on the grade. Our consistent chemistry ensures accurate final composition.
Cast Iron Production
In gray and ductile iron, manganese helps control the pearlite/ferrite balance and neutralizes sulfur's negative effects. Typical additions are 0.3-1.0% depending on iron type.
Welding Electrodes & Fluxes
Ground to fine powder and used in electrode coatings or as a component of agglomerated fluxes for submerged arc welding, improving arc stability and weld metal toughness.
Specialty Applications
High-grade Mn78 and Mn80 are used in stainless steel production (e.g., 200 series) and non-ferrous alloys. Our technical team can advise on the optimal grade for your specific process.

Frequently Asked Questions – High Carbon Ferro Manganese
What is the difference between Mn65-C7.0 and higher manganese grades like Mn75-C2.0?
+
Mn65-C7.0 contains 65-70% Mn and up to 7% carbon, making it ideal for general carbon steel deoxidation and alloying where high manganese is not required. Higher grades like Mn75-C2.0 offer higher manganese (75-78%) and lower carbon (≤2.0%), suitable for low-carbon steel grades or when a more concentrated manganese addition is needed to minimize gangue volume. The choice depends on your steel specification and cost optimization.
Is it possible to entrust a third-party inspection to check the quality before shipment?
+
Certainly, we support third-party inspections by internationally recognized quality inspection agencies such as SGS and BV to verify product quality before shipment. The inspection covers product appearance, weighing, dimensions, and chemical composition analysis. The entire inspection process will be documented with photos and written records, which will be provided to you together with the final inspection report. This ensures you have no concerns regarding product quality.
Can High Carbon Ferro Manganese be used in stainless steel production?
+
Yes, but typically the lower-carbon grades such as Mn78-C1.5 or Mn80-C0.7 are preferred for stainless steels to avoid excessive carbon pickup. For 200-series stainless steels (e.g., 201, 202), higher manganese is essential, and our medium- and low-carbon grades are commonly used. We recommend discussing your specific stainless grade with our technical team.
What sizes are best for ladle addition in steelmaking?
+
For ladle additions, lumps in the range of 10-80mm are typical to ensure rapid dissolution and avoid excessive fines. For injection or cored wire, finer granules (1-6mm) or powder (-100 mesh) are used. We can supply custom sizes based on your furnace type and addition practice.
Do you provide a certificate of analysis with each shipment?
+
Absolutely. Every batch of Ferro Manganese is tested in our ISO 17025 accredited laboratory, and a Certificate of Analysis (COA) showing Mn, C, Si, P, S, and other elements is provided with the shipping documents.
What is your production capacity for High Carbon Ferro Manganese?
+
We have an annual production capacity exceeding 80,000 metric tons of ferro manganese across all grades, including Mn65, Mn70, Mn75, Mn78, and Mn80. We can accommodate both containerized and bulk vessel shipments.
