Steel is an alloy that consists mostly of iron and has a carbon content between 0.2% and 2.1% by weight, depending on the grade. Carbon is the most common alloying material for iron, but various other alloying elements are used, such as manganese, chromium, vanadium, and tungsten.[1] Carbon and other elements act as a hardening agent, preventing dislocations in the iron atom crystal lattice from sliding past one another. Varying the amount of alloying elements and the form of their presence in the steel (solute elements, precipitated phase) controls qualities such as the hardness, ductility, and tensile strength of the resulting steel. Steel with increased carbon content can be made harder and stronger than iron, but such steel is also less ductile than iron.
Alloys with a higher than 2.1% carbon content are known as cast iron because of their lower melting point and good castability. Steel is also distinguishable from wrought iron, which can contain a small amount of carbon, but it is included in the form of slag inclusions. Two distinguishing factors are steels increased rust resistance and better weldability.
Though steel had been produced by various inefficient methods long before the Renaissance, its use became more common after more-efficient production methods were devised in the 17th century. With the invention of the Bessemer process in the mid-19th century, steel became an inexpensive mass-produced material. Further refinements in the process, such as basic oxygen steelmaking (BOS), lowered the cost of production while increasing the quality of the metal. Today, steel is one of the most common materials in the world, with more than 1.3 billion tons produced annually. It is a major component in buildings, infrastructure, tools, ships, automobiles, machines, appliances, and weapons. Modern steel is generally identified by various grades defined by assorted standards organizations.
Iron is a chemical element with the symbol Fe (from Latin: ferrum) and atomic number 26. It is a metal in the first transition series. It is the most common element in the whole planet Earth, forming much of Earths outer and inner core, and it is the fourth most common element in the Earths crust. It is produced in abundance as a result of fusion in high-mass stars, where the production of nickel-56 (which decays to iron) is the last nuclear fusion reaction that is exothermic, becoming the last element to be produced before collapse of a supernova leads to events that scatter the precursor radionuclides of iron into space.
Like other Group 8 elements, iron exists in a wide range of oxidation states, -2 to + 6, although +2 and +3 are the most common. Elemental iron occurs in meteoroids and other low oxygen environments, but is reactive to oxygen and water. Fresh iron surfaces appear lustrous silvery-gray, but oxidize in normal air to give iron oxides, also known as rust. Unlike many other metals which form passivity oxide layers, iron oxides occupy more volume than iron metal, and thus iron oxides flake off and expose fresh surfaces for corrosion.
Iron metal has been used since ancient times, though lower-melting copper alloys were used first in history. Pure iron is soft (softer than aluminum), but is unobtainable by smelting. The material is significantly hardened and strengthened by impurities from the smelting process, such as carbon. A certain proportion of carbon (between 0.2% and 2.1%) produces steel, which may be up to 1000 times harder than pure iron. Crude iron metal is produced in blast furnaces, where ore is reduced by coke to cast iron. Further refinement with oxygen reduces the carbon content to make steel. Steels and low carbon iron alloys with other metals (alloy steels) are by far the most common metals in industrial use, due to their great range of desirable properties.

The Thermo Mechanically Treated TMT steel bars also known as reinforcement steel and wire rods are primarily used by the construction industry. Its high-corrosion and rust- resistance features make it the first choice for buildings in costal areas and in areas of high humidity. The manufacturing process of TMT involves 3 stages of treatment – Quenching, Self-tempering and Atmospheric Cooling.
Stage 1 – The reheated billet first gets rolled and is passed through the quenching process where the surface of the bar is instantly cooled to martensite while the core is still austenitic.
Stage 2 – Heat from the core of the bar dissipates to the surface allowing forming tempered martensite, while the core remains austenitic. This process is called self-tempering.
Stage 3 – Due to atmospheric cooling, wherein the bar is cooled on the cooling bed, results in the austenitic core being converted into ductile ferrite-pearlite core; which gives TMT its unmatched qualities of strength and ductility
Its ductility and bend ability on the other hand, makes it the perfect choice for buildings in seismic zones for high-stress construction structures. They find wide application for a number of high-specialty and custom constructions including coastal and marine environments which are susceptible to corrosion and general purpose concrete reinforcement structures like Homes, Apartments, Hospitals, Hotels, Auditoriums, Bridges, Dams, Flyovers, Thermal & Hydel Power Plants, Industrial Structures, High-rise buildings Earthquake-sensitive zones, Underground platforms in Metro Railways and Rapid Transport Systems.
