Among pig iron and wrought iron, which is used for making tools? Why?
Wrought Iron is used for rivets, chains, ornamental iron work, railway couplings, water and steam pipes, bolts and nuts, horse shoe bars, hand rails, straps for timber roof trusses, boiler tubes, roofing sheets, etc.
Wrought Iron is used in making tools because it is easily forged and welded, can be used to form temporary magnets, it is ductile, malleable and tough, etc.

Identify the correct statement from the following :
The main difference between cast iron and pig iron is that:
The advantage(s) of using $${O}_{2}$$ rather than air in the steel industry is (are): $$(I)$$ There is a faster conversion, so a given plant can produce more in day $$(II)$$ Larger quantities can be handled $$(III)$$ It gives a pure product, and the surface is free from nitrides.
Which of the following process is not associated with steel making?
The conversion of pig iron to steel frequently requires the addition of: $$(I)$$ oxygen or iron oxide $$(II)$$ transition elements $$(III)$$ inner transition elements $$(IV)$$ silica
Describe how the following changes are brought about: Pig iron into steel.
