Iron sands or other raw source of iron is smelted and the product of that smelt is pig iron.

Pig iron is refined and becomes wrought iron.

Wrought iron contains varying quantities of carbon. In its raw state it contains too much carbon to be useful, so we reduce the carbon by washing the iron, and getting rid of the other impurities as well, like slag, what we finish up with is wrought iron with a very low carbon content, but we can then add carbon to this low carbon content iron and turn it into steel

Wrought iron can be carburised to become steel, but the carburisation process only produces small quantities of steel. The lamination of carburised iron (steel) and wrought iron provided a tough material that held an edge :- ie, "mechanical damascus".

So:-

iron bearing raw material > smelt > pig iron > wrought iron > steel

There is a lot of information on iron and steel technology published on the net. Heaps of stuff. If you have an interest in this all you need to do is use google.

You could start with this article:-
