High Carbon Silico Manganese alloys are developed under the supervision of highly qualified professionals with precise chemical specifications. Our expertise lies in manufacturing these high carbon alloys and carbon manganese alloys in standard as well as customized form to meet with the drawings and specifications of our esteemed clients.

Silicomanganese (SiMn), a ferroalloy with high contents of manganese and silicon, is made by heating a mixture of the oxides manganese oxide (MnO2), silicon dioxide (SiO2), and iron oxide (Fe2O3), with carbon in a furnace. They undergo a thermal decomposition reaction. It is used as a deoxidizer and an alloying element in steel.

Specifications:-
Mn .: 60% min
Silicon: 14% / 15% min
Phos .: 0.35% max
Sulphur : 0.04% max
Carbon: 2% max
Size: 10-125 mm


Ferro Manganese

Ferromanganese, a ferroalloy with high content of manganese, is made by heating a mixture of the oxides MnO2 and Fe2O3, with carbon, usually as coal and coke, in either a blast furnace or an electric arc furnace-type system, called a submerged arc furnace. ... Ferromanganese is used as a deoxidizer for steel.

Ferro manganese is an alloy of iron and manganese containing usually about 80% manganese.
Ferro manganese is used mainly to counteract the bad effects of sulfur. It also acts as a deoxidizer and combines with sulfur, thereby improving the hot-working properties of the product. It imparts metallurgical properties such as increased strength, hardness toughness and hardenability.

Specifications:-
Mn .: 70% min
Silicon: 1.5% max
Phos.: 0.40% max
Sulphur : 0.05% max
Carbon: 8% max
Size: 10 mm to 125 mm
