It is because the iron is not strong enough to be able to handle the pressures that steel can. Pure iron is to soft and weak to be of any use and the iron from the blast furnace has too much carbon in it to be useful. That is the real reason
Iron is used to make the steel, which most cars frames, bodies, bolts and engine internals are still made of.
The main element of steel is Iron but has been added with carbon to make steel. The main element of steel is Iron but has been added with carbon to make steel.
Steel is made from iron. We combine a small amount of carbon with iron to get (make) steel.
To make iron and steel.

Melted iron combined with carbon creates steel.
Iron and carbon combine to make steel, which is a commonly used alloy known for its strength and durability. The amount of carbon in the iron determines the properties of the resulting steel, such as its hardness and ability to be shaped through heat treatment.
good question actually carbon and iron react together to make steel but coal although it does contain carbon it also contains nitrogen and oxygen and is already reacted to form steel carbon needs to react with iron so if the carbon could be extracted from coal and then heated up with iron it would indeed form steel but it is a lot of hassle and would be rather expensive.
