Cast Iron has been sub-divided into 5 different classes when the composition is changed or tampered with. Each of these classes have different properties but in comparison with Steel which also has its grades ranging from low to high grade carbon steel which are just alloys of purified iron with carbon and hints of other metal elements such as Manganese and Nickel so the production of Steel products differs only slightly from the commercial production of Iron. Steel which is the easily formed, cheap and yet strong and tough allowing for it to be extremely versatile creating products ranging from paperclips to reinforcing elements in the construction of buildings and skyscrapers.
