Uses. About 98% of world iron ore production is used to make iron in the form of steel. Iron in cast form has many specific uses (e.g. pipes, fittings, engine blocks) but pure iron is quite soft. Adding a small amount of carbon (usually less than 1%) makes iron into steel which is significantly harder and extremely versatile.
