Pearlitic iron should be cooled quickly below the Ac3-temperature (which is mostly above 800°C) to avoid the ferrite formation. The shakeout cooling should be similar to the heat treatment cooling, which in this case is air cooling. Austenitic ductile iron (Ni-resist grades) should cool quickly through the temperature zone of 700 to 550°C.
