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. This micrograph has been taken transverse to the directionality and hence the directionality present in the carbide is not apparent
