FERRO ALLOYS
Ferroalloys are one of the important inputs in the manufacture of alloys and
special steel. They are used as deoxidisers and alloy additives in the steel
manufacturing process. They impart special properties to steel. The alloys
provide increased resistance to corrosion, improve hardness & tensile strength at
high temperature, impart wear and abrasion resistance and increases creep
strength etc. The growth of Ferroalloys Industry is, thus, linked with the
development of the Iron and Steel Industry, Foundry Industry and to some extent
Electrode Industry. The principal ferroalloys are chromium, manganese and
silicon. The product series consists mainly of ferromanganese, silicomanganese,
ferrosilicon and ferrochrome.
Ferroalloys are classified into two main categories, viz, bulk ferroalloys and noble
ferro alloys. Bulk ferroalloys are majorly used in stainless steel & carbon steel.
Most of the boble ferroalloys are made from rare-earth minerals and are
expansive to produce as compared to bulk ferroalloys. At present, major portion
of the ferroalloys produced is exported. Ferromanganese, silicomanganese,
ferrosilicon, high carbon ferrochrome and chargechrome are exported after
meeting the domestic requirements. As per Nation’s database the total installed
capacity of bulk Ferroalloys Industry in India is estimated at 5.10 million tonnes
per annum and for noble ferroalloys it is 50,000 tonnes per annum. The products
covered are Manganese alloys (HC, MC & LC ferro chrome, silicochrome and
charge chrome) and Nobel ferroalloys (ferromolybdenum, ferrovanadium,
3
ferrotungsten, ferrosilicon magnesium, ferroboron,
ferrotitanium etc.). The details are furnished in Table- 1.

FOREIGN TRADE
Exports
In 2018-19, exports of ferroalloys (total) decreased slightly to 19,42,134 tonnes in
2018- 19 from 19,55,751 tonnes in the previous year. In terms of value, the ferro-
alloys exports increased to ` 14,962 crore in 2018-19 from 14,328 crore in 2017-18.
Out of total export, in terms of quantity, majority were exports of ferrochrome
(44%) followed by ferrosilico-manganese (39%), ferromanganese (14%) and
ferrosilicon (1%). The other ferroalloys together accounted for remaining 2% of
exports in 2018-19. Exports were mainly to Republic of Korea & China (15% each),
UAE (11%), Japan (10%), Taiwan (7%), Italy (4%), Thailand & Malaysia (3% each)
and USA & Netherlands (2% each).

ALLOYS
Superalloys are alloys that exhibit excellent mechanical strength and creep
resistance at high temperatures, good surface stability, and corrosion and
oxidation resistance. The corrosion-resistant superalloys are widely used in
extreme environments where tremendous heat and corrosion resistance is
paramount to the integrity of the end product. Chemical and petrochemical
processing, Aero-engines, power plants, and oil and gas industries widely use
these superalloys.
Many of the industrial nickel-based superalloys contain alloying elements,
including chromium (Cr), aluminum (Al), titanium (Ti), molybdenum (Mo),
tungsten (W), niobium (Nb), tantalum (Ta) and cobalt (Co).
Our manufacturer supplies most of the superalloys in the form of sheet, plate and
bar forms.
