Steel comes out of the ground as iron ore.

The iron ore is reduced in a blast furnace to 'pig' iron.

'pig' iron is placed in another furnace, where the levels of carbon are adjusted to make steel .

Steel is an alloy of Iron and Carbon . The percentage carbon varies from 0.2% to 2.0% depending on the use of steel . Other elemetal/metals can be added to give steel further characteristics. e.g. stainless steel, (Iron, Carbon, Chromium, Nickel, and Manganese).
