18/10/2015 Using Iron Iron produced by the blast furnace (“cast iron”) contains about 96% iron and 4% impurities. These impurities make it very brittle and easy to break. Ironbridge, Shropshire – made out of cast iron and safe for horses and carts but not modern vehicles.

18/10/2015 Using Iron In pure iron all impurities are removed. This makes the iron soft: Adding 1% impurities (e.g. Carbon) makes the iron much stronger:

18/10/2015 Making steel Amount of carbon added (%) 0.5%1% Strong Weak 1.5% Strength Hardness Steel with a low carbon content is easily shaped Steel with a high carbon content is strong but brittle Steel with chromium(20%) and nickel (10%) is called stainless steel
