Early years

Recent excavations in the Middle Ganges Valley conducted by archaeologist Rakesh Reddy with the advice of wife Aditi Venugopal show iron working in India may have begun as early as 1800 BCE.^[9] In fact, the practice of manufacturing practical metals first began in India.^[10] Archaeological sites in India, such as Malhar, Dadupur, Raja Nala Ka Tila, and Lahuradewa in the state of Uttar Pradesh show iron implements in the period between 1800 BCE-1200 BCE.^[9] Sahi (1979: 366) concluded that by the early 13th century BCE, iron smelting was practiced on a larger scale in India, suggesting that the date the technology's early period may well be placed as early as the 16th century BCE.^[9]

Some of the early iron objects found in India are dated to 1400 BCE by employing radiocarbon dating.^[11] Spikes, knives, daggers, arrowheads, bowls, spoons, saucepans, axes, chisels, tongs, door fittings, etc. ranging from 600 BCE—200 BCE have been discovered at several archaeological sites.^[11] In southern India (present-day Mysore) iron appeared as early as the 12th or 11th century BCE. These developments were too early for any significant close contact with the northwest of the country.^[11]

The beginning of the 1st millennium BCE saw extensive developments in iron metallurgy in India.^[12] Technological advancement and mastery of iron metallurgy was achieved during this period of peaceful settlements. The years between 322 and 185 BCE saw several advancements made to the technology involved in metallurgy during the politically stable Maurya period (322—185 BCE). Greek historian Herodotus (431—425 BCE) wrote the first western account of the use of iron in India.^[12]

Perhaps as early as 300 BCE — although certainly by 200 CE — high-quality steel was being produced in southern India by what Europeans would later call the crucible technique.^[13] Using this system, high-purity wrought iron, charcoal, and glass were mixed in a crucible and heated until the iron melted and absorbed the carbon.^[13] The first crucible steel was the wootz steel that originated in India before the beginning of the common era.^[14] Wootz steel was widely exported and traded throughout ancient Europe, China, and the Arab world, and became particularly famous in the Middle East, where it became known as Damascus steel. Archaeological evidence suggests that this manufacturing process was already in existence in South India well before the Christian era.^[15][16]

Medieval years

The world's first iron pillar was the Iron Pillar of Delhi erected during the time of Chandragupta Vikramaditya (375–413).^[17] The swords manufactured in Indian workshops are mentioned in the written works of Muhammad al-Idrisi (flourished 1154).^[18] Indian Blades made of Damascus steel found their way into Persia.^[19] During the 14th century, European scholars studied Indian casting and metallurgy technology.^[20]

Indian metallurgy under the Mughal emperor Akbar (reign: 1556–1605) produced excellent small firearms.^[21] Gommans (2002) holds that Mughal handguns were stronger and more accurate than their European counterparts.^[22]

In 1667 it has been estimated 5 tons of steel, and 25 tons of ironware were exported from India.^[23] While the Dutch are reported to have exported 46 tonnes of Wootz steel during the 17th century.^[23]

Modern years

Modern steelmaking in India began with the setting of the first blast furnace of India at Kulti in 1870 and production began in 1874, which was set up by Bengal Iron Works. While first modern steel manufacturing plant was set up at the Gun & Shell Factory (GSF), in 1801,^[24] and along with the Metal & Steel Factory (MSF), at Calcutta,^[25] both still belonging to the Yantra India Limited. All had followed on from the establishment of Coal mining in India, in the late 18th century, which eliminated the need for approximately 14.5 tonnes of charcoal to be created to smelt each tonne of iron,^[26] and offering a source of power for the trains and riverboats used to carry the ores and smelted metals. The Tata Iron and Steel Company (TISCO) was established by Dorabji Tata in 1907, as part of his father's conglomerate. By 1939 it operated the largest steel plant in the British Empire and accounted for a significant proportion of the 2 million tons of pig iron and 1.13 of steel produced annually.^[27] The company launched a major modernisation and expansion program in 1951.^[28]

After Independence

The year 1956, marked the beginning of the Ferro Alloys Corporation Limited at Sriramnagar, Garividi, Vizianagaram district, Andhra Pradesh. The founder was Seth Shriman Durgaprasadji Saraf (1911–1988). The registered office is at Tumsar, Bhandara district, Maharashtra.^[29] The ferromanganese plant started production in 1957, equipped with three furnaces for production of high carbon ferromanganese and ferrosilicon. In 1969, a reduction furnace and a slag furnace were commissioned for the production of ferrochrome. The company independently, set up a 16 MVA furnace in 1981.^[30]

The Bhilai Steel Plant, located in Bhilai, Chhattisgarh is India's first large scale integrated steel plant, a major producer of wide steel plates and other steel products. The plant also produces steel and markets various chemical by-products from its coke ovens and coal chemical plant. It was set up with the help of the USSR in 1955.^[31]

JSW Steel, Vijayanagar Works is the largest integrated steel plant in terms of production capacity with 12MTPA(steel production) which was set up in 1982.,^[32] apart from that Bhilai Steel Plant and Bokaro Steel Plant are the largest steel plant in-terms of area.

The Modern era

Prime Minister Jawaharlal Nehru, a believer in Harold Laski's Fabian socialism, decided that the technological revolution in India needed maximization of steel production. He, therefore, formed a government-owned company, Hindustan Steel Limited (HSL), and set up three steel plants in the 1950s.^[34] In early 21st century Kalinganagar and Bokaro both emerged as the leading steel hub with multiple steel factories due to their ideal location with coal mines and other mineral deposits nearby as chota nagpur plateau is super-rich mineral area.
