Iron ore is reduced to pig iron or sponge iron which then becomes the starting material for making iron and steel.

Adjectives to kind of iron and steel are given according to their performance on dynamic platform. Iron and steel are differentiated with the quantity of carbon element present in the metal. Steel have carbon ranging from 0.05% to 1.70%. Iron has carbon above 1.7% and goes up to 4%. Mild steel have a carbon range between 0.15 to 0.30%. Mild steel are also known as structural steel.

Iron has variations such as white iron and gray iron depending upon their carbon content and the kind and color of the fracture they reveal on breaking. Malleable cast iron starts with a white fracture but is converted to ductile properties by heat treatment. Its refined version is ductile iron wherein graphite flakes are converted into globule or spheroids to give it a ductile property. Ductile iron has mechanical properties very similar to structural or mild steel. With a typical austempering cycle this has enhanced properties almost replacing alloy steel items such as even crank shafts.

Till now, nobody has thought of naming ductile iron as mild iron. Mild iron, as such is non-existent in Metallurgy and mostly used in medical science as mild iron deficiency in human.
