When it comes to steel production, some countries have a clear lead. Let's take a look at the biggest producers of steel, including India, in the world.
China
Steel production (2011): 683.3 million tonnes
Steel is an alloy that consists mostly of iron and has a carbon content between 0.2 per cent and 2.1 per cent 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.

European Union
Steel production (2011): 177.4 million tonnes
Carbon and other elements act as a hardening agent, preventing dislocations in the iron atom crystal lattice from sliding past one another.

Steel production (2011): 107.6 million tonnes
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.

The Unites States
Steel production (2011): 86.2 million tonnes
Steel with increased carbon content can be made harder and stronger than iron, but such steel is also less ductile than iron.

India
Steel production (2011): 72.2 million tonnes
Alloys with a higher than 2.1 per cent carbon content are known as cast iron because of their lower melting point and good castability.

Steel production (2011): 68.7 million tonnes
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.

Steel production (2011): 44.3 million tonnes
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.

Mexico
Steel production (2011): 18.1 million tonnes
The steel industry is often considered to be an indicator of economic progress, because of the critical role played by steel in infrastructural and overall economic development.

Steel production (2011): 15.6 million tonnes
Between 2000 and 2005, world steel demand increased by six per cent. Since 2000, several Indian and Chinese steel firms have risen to prominence like Tata Steel (which bought Corus Group in 2007), Shanghai Baosteel Group Corporation and Shagang Group.
ArcelorMittal is, however, the world's largest steel producer.
