Silico manganese is used as a de-oxidant, sulfide former and alloying element in the steel industry, or in the production of other manganese alloys. In the case of stainless steel, it is also used to substitute expensive nickel in some austenitic grades. It is produced from manganese-rich slag – a by-product from ferro manganese production. Silico-manganese accounts for over 75% of Indian manganese alloy exports followed by ferro-manganese and other manganese based alloys.
There are three variants of Silico Manganese:
• High Carbon Silico Manganese
• Medium Carbon Silico Manganese
• Low Carbon Silico Manganese
| Specification (A) | Specification (B) | |
| Mn. | 60-65% | 65-70% |
| Si | 14% Max | 16% Max |
| C | 2.5% Max | 2% Max |
| P | 0.30% | 0.25% |

Ferro manganese, when added during the steel-making process, helps in lowering the melting point of steel. It is made by heating the mixture of manganese oxide and ferric oxide with carbon in a blast or electric arc furnace.
| Specification (A) | Specification (B) | |
| Mn. | 70-75% | 75-80% |
| Si | 1.5% max | 1.5% max |
| C | 8% max | 8% max |

| S | 0.030% max | 0.030% max |
| Size | 10-50mm or any other size required by you. | 10-150mm or any other size. |
Ferrosilicon is used as a source of silicon to reduce metals from their oxides and to deoxidize steel and other ferrous alloys. Ferrosilicon is also used for manufacture of silicon, corrosion-resistant and high-temperature-resistant ferrous silicon alloys, and silicon steel for electromotors and transformer cores.
