Reexamining Shakeout to Control Time, Temperature

Mar 12, 2021Pearlitic iron should be cooled quickly below the Ac3-temperature (which is mostly above 800C) 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 550C.
