High Carbon Ferro Manganese is a widely used ferroalloy in steel production. It’s primarily an alloy of Manganese and Iron, typically containing 70-80% Manganese and 6-7% Carbon. Its primary functions are as a deoxidizer and desulfurizer, improving steel quality and enhancing its properties like strength, hardness, and wear resistance. High-Carbon Ferro Manganese is produced by smelting Manganese Ores in Blast Furnaces or Electric Arc Furnaces.
Function in Steelmaking:
Desulfurizer: It reacts with sulfur in molten steel to form manganese sulfide, which is less harmful than iron sulfide and can be removed as slag.
Alloying Agent: Manganese is a key alloying element in steel, improving its strength, hardness, and corrosion resistance.
Applications:
Steel Manufacturing: Widely used in the production of various steel grades, including flat steel, high-strength steel, and stainless steel.
Foundries and Welding: Used in foundry operations and for producing welding electrodes.

High carbon ferromanganese is available in 3 grades.
Grade 1
Grade 1 consists of Manganese at 70%-75%, a maximum of 1.5% to 2.0% of silicon content, Carbon between 6%-7.5% and maximum levels of sulphur and phosphorus at 0.05% and 0.30% respectively.
Grade 2
Grade 2 consists of Manganese at 75%-80%, Silicon at 1.5% to 2.0% maximum, Carbon at 6%-7.5% and the top levels of sulphur and phosphorus at 0.05% and 30%.
Grade 3
Grade 3 consists of Manganese - 80%-85% Silicon level at 1.5% to 2.0% maximum, and the Carbon between 6%-7.5%, sulphur and phosphorus being at the same levels as grade 1 and 2 Ferromanganese.
