    In its pure form, iron is soft and generally not useful as an engineering material; the principal method of strengthening it and converting it into steel is by adding small amounts of carbon. In solid steel, carbon is generally found in two forms. Either it is in solid solution in austenite and ferrite or it is found as a carbide.

  • The green edge of steel: Cutting through carbon

     · The majority of steel is currently manufactured in blast furnaces. Iron ore and coke, made from coking coal, sinter and limestone, is fed into the top of the furnace. Hot air—approximately 1,000°C—is injected at the bottom of the furnace. As the coke burns, temperatures higher than 2,000°C are reached and this heat creates molten iron.
