Steels

Steel is an alloy of iron and carbon and there are various steels with popular names with carbon content varying from 0.05% to 1.7%. Steels having only carbon as the additional element apart from iron are called plain carbon steels.

Steel is produced by oxidizing the impurities in molten pig iron and then adding the specified carbon which will give required combination of strength, ductility and hardness.

The processes used to produce steel are a) open hearth process b) the Bessemer Process and c) the electric furnace process. The finished molten steel is to poured into ingots in sizes suitable for used by rolling mills.

According to the World Steel Association, there are over 3,500 different grades of steel, encompassing unique physical, chemical, and environmental properties.

Dead Mild Steel

Dead mild steel contains carbon up to 0.1%. It is the softest and the most ductile material and possesses excellent machinability and weldability.  It is rolled into sheet and is also available in bar form. It is used for rivets and solid drawn steel tubes.
