Ferro alloys have extensive use in wide range of industries because of its flexibility to meet toughness, strength, and impact of different industrial targets. This flexibility depends on the heat treatment procedures. Examples of ferro alloys include of alloy steels, carbon steels, stainless steels and etc which is classified as below:
- Carbon steels are a kind of ferroalloys that contain carbon with small levels of other alloying elements, such as aluminum or manganese.
- Alloy steels contain low to high levels of elements such as nickel, ferrochrome, vanadium and ferromolybdenum.
- Stainless steels are highly corrosion resistant, ferroalloys that contain of ferrochrome, nickel additions.
- Cast iron, ferroalloys, contains huge amounts of carbon.
- Cast steel alloy are classified by pouring molten iron into a mold.
- Iron Alloy is the major ferroalloys used in most industrial applications.

Ferro alloys are roughly new discovery in the steel industry that mainly is using to increase steel usages in various industries.
The main chemical task of the ferro alloys is dehydration and de-graphitization which depending on the type of consumption, is charged with a certain ratio in the furnaces and most commonly used are ferro silicon and ferromanganese. For example, for the producing of billets with 5sp grade, 4 kg of ferro silicon is needed per ton, which can vary in different grades.

Ferro silicon is producing in different specifications such as follow:
Trademark: FeSi
Chemical Analyze: Si: 75% Al: 2% max C: 0.2% P: 0.03 S: 0.04max Size: 10-60mm
Melting point (°C): 1250
Ferro chrome is producing commonly in couple grades as High-Carbon and Low-Carbon:
Trademark: FeCr
Chemical Analyze(HC): Cr: 65% C: 6-8% Si: 2.5% P: 0.02 Size: 10-60mm
Melting point (°C): 1350
Today, the usage of ferro alloys, such as ferro silicon, plays a significant role in the steel industry, so that the production of raw steel, stainless steel and etc, without ferro silicon or ferro chrome will never be possible. On the other hand, the use of ferro silicon which has the richness raw materials in Iran such as silicaOre, charcoal, electrode pulp, electricity and etc… is due to that this production in Iran is currently increasing and has played an important role in the Iranian ferro alloys market. That’s why we are going to increase the export of this strategic item in the steel industry to neighboring countries.
Due to this, the Avijeh Alloy Co. has over 5000 tons export of Ferro silicon to the foreign countries, is going to extent its cosmopolitan goals, and this increase of Ferro silicon exports will be defined as well in the coming years.
Ferro Silicon Manganese is integrated of Manganese and Silicon that usually called with Mn-Si character index such as 65-15
Trademark: FeSiMn
Chemical Analyze: Mn: 65% Si: 16% P: 0.2%max S: 0.03%max Size: 10-60mm
Melting point (°C): 1190
