The hardening programs are carefully matched to the various Alleima steel grades. Choose the furnace type to suit either individual pieces or an entire batch. Then select a steel grade.
The hardening cycle starts with heating from room temperature to the required hardening temperature (A = austenitizing) of between 1050 and 1090°C (1922 and 1994°F), depending on the steel grade.
The material is then quenched (Q = quench) to room temperature in the space of less than 2 minutes, possibly followed by deep-freezing (DF = deep-freezing) to between –20 and -70°C (-4 and -94°F).
This is followed by the tempering process (T = tempering), during which the material is heated to 175 - 350°C (347 - 662°F), depending on the required hardness.
