The Iron and Steel industry in India is among the most important industries within the country. India surpassed Japan as the second largest steel producer in January 2019. [ 1 ] As per worldsteel , India's crude steel production in 2018 was at 106.5 million tonnes (MT), 4.9% increase from 101.5 MT in 2017, which means that India overtook Japan ...
An iron-carbon phase diagram showing the conditions necessary to form different phases An incandescent steel workpiece in a blacksmith's art. Iron is commonly found in the Earth's crust in the form of an ore, usually an iron oxide, such as magnetite or hematite.
Details of the top of iron pillar, Qutb Minar, Delhi. The iron pillar in India was produced by the forge welding of pieces of wrought iron. In a report published in the journal Current Science, R. Balasubramaniam of the IIT Kanpur explains how the pillar's resistance to corrosion is due to a passive protective film at the iron-rust interface.
In this system, high-purity wrought iron, charcoal, and glass were mixed in crucibles and heated until the iron melted and absorbed the carbon. The resulting high-carbon steel, called fūlāḏ by the Arabs (Arabic: فولاذ, romanized: fūlāḏ, lit. 'steel; wootz') and wootz by later Europeans, was exported throughout much of Asia and Europe.
Wrought iron is an iron alloy with a very low carbon content (less than 0.05%) in contrast to that of cast iron (2.1% to 4.5%). It is a semi-fused mass of iron with fibrous slag inclusions (up to 2% by weight), which give it a wood-like "grain" that is visible when it is etched, rusted, or bent to failure.
Wrought iron contains less than 0.25% carbon but large amounts of slag that give it a fibrous characteristic. [134] Wrought iron is more corrosion resistant than steel. It has been almost completely replaced by mild steel, which corrodes more readily than wrought iron, but is cheaper and more widely available.
Reinforcing bars in masonry construction have been used since antiquity, with Rome using iron or wooden rods in arch construction. Iron tie rods and anchor plates were later employed across Medieval Europe, as a device to reinforce arches, vaults, and cupolas.
