Further information
Medium carbon steel that has been austenitised and subsequently quenched. If the quench is insufficiently rapid bainite is formed instead of martensite. This sample was taken from the centre of a quenched item. Cooling rates in the centre are slower and hence the formation of the bainite that can be observed.
