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,

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.
