ANNEALING

To prevent excessive scaling or decarburisation pack in spent carburising mixture
or other similar inert media in a sealed container.  Heat to 850°C / 880°C, soak
thoroughly at temperature then cool at a range not faster than 25°C per hour to
650°C.  The parts may then be air cooled.  A maximum hardness of 248 HB
should be obtained.
