Ferro Manganese mn75-c8.0 – Product Overview
Ferro Manganese mn75-c8.0 is a high-carbon grade of ferro manganese with a minimum manganese content of 75% and carbon content up to 8.0%. It is produced by carbothermic reduction of manganese ore in submerged arc furnaces. Our mn75-c8.0 grade offers a well-balanced impurity profile (Si, P, S) making it suitable for a wide range of steelmaking applications, from deoxidation to alloying. It serves as an essential additive to improve the mechanical properties of steel, such as tensile strength, hardness, and wear resistance.

Application Guidelines – Ferro Manganese mn75-c8.0
Ferro Manganese mn75-c8.0 is a versatile material with the following primary applications:
Steel Deoxidation
Added to molten steel (typically 0.1-0.5% depending on steel grade) to combine with oxygen and form manganese oxide, which floats out of the melt. This prevents gas porosity and improves ingot surface quality.
Alloying for Strength & Wear Resistance
Manganese is an austenite stabilizer and increases hardenability. In carbon steels, addition rates of 0.5-1.5% Mn are common. In wear-resistant steels (e.g., Hadfield manganese steel), Mn content can reach 12-14%, where our mn75-c8.0 serves as a cost-effective base alloy.
Desulfurization
Manganese has a high affinity for sulfur, forming manganese sulfide inclusions which are less harmful than iron sulfides. This improves hot ductility and reduces the risk of hot cracking during rolling or forging.
Foundry & Cast Iron
In gray and ductile iron, manganese helps control the pearlite/ferrite ratio, enhancing strength and hardness. Typical addition rates range from 0.3% to 1.0% depending on the desired matrix structure.
Typical Addition Rates (Steelmaking)
In steelmaking, addition rates typically range from 1 kg to 5 kg per ton of steel, depending on target manganese specification and base chemistry. Our technical team can assist with optimal sizing and addition practices.

Frequently Asked Questions – Ferro Manganese mn75-c8.0
What is the difference between mn75-c8.0 and lower/higher carbon grades like mn75-c2.0?
+
The key difference lies in carbon content. mn75-c8.0 is a high-carbon grade (C≤8.0%) suitable for general steelmaking where carbon is not detrimental. mn75-c2.0 is a medium-carbon grade (C≤2.0%) used when lower carbon pick-up is required, such as in low-carbon or alloy steels. mn78-c1.5 and mn80-c0.7 are low-carbon grades for specialty steels requiring minimal carbon addition.
Can Ferro Manganese mn75-c8.0 be used in stainless steel production?
+
Yes, but with caution. While manganese is used in some stainless grades (e.g., 200 series) to replace nickel, the high carbon content of mn75-c8.0 may not be suitable for low-carbon stainless steels. For such applications, low-carbon grades like mn80-c0.7 are recommended. We advise discussing your specific stainless grade with our technical team.
What sizes are best for steelmaking additions?
+
For ladle additions, lumps in the range of 10-80mm are typical to ensure good penetration and dissolution without excessive fines. For conveyor-fed systems, smaller granules (2-15mm) may be preferred. We can supply custom sizes based on your furnace type and charging practice.
Do you provide a certificate of analysis with each shipment?
+
Absolutely. Every batch of Ferro Manganese mn75-c8.0 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 Ferro Manganese mn75-c8.0?
+
We have an annual production capacity exceeding 60,000 metric tons of ferro manganese across various grades, including mn65-c7.0, mn70-c7.5, mn75-c2.0, mn75-c8.0, mn78-c1.5, and mn80-c0.7. We can accommodate both containerized and bulk vessel shipments.
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.
