extraction of pig iron from a blast furnance

Why iron from the blast furnace is hard and brittle? | …

Pure iron is too soft for many uses.Iron from the blast furnace is an alloy of about 96 percent iron, with carbon and some other impurities.It is hard, but too brittle for most uses, so most iron from the blast furnace is converted into steel by removing some of the carbon.
