A Short History of Steel and the Bessemer Process

Jul 22, 2018Cast iron is strong, but it suffers from brittleness due to its carbon content, making it less than ideal for working and shaping. As metallurgists became aware that the high carbon content in iron was central to the problem of brittleness, they experimented with new methods for reducing the carbon content in order to make iron more workable.
