Further information
Low carbon steel with a microstructure consisting mostly of ferrite. Manganese is added to steel to remove oxygen and sulphur. It causes a reduction in the resulting grain size and hence the steel is tougher and stronger. This sample has been normalised, recrystallising the ferrite. The pearlite is unable to do this and consequently retains its directionality.
