Forging - rolling temperature 1160 - 1050 C (2120 - 1920 F).
Melting occurs above 1220 C (2230 F). This means that the steel is relatively sensitive to
”Burning” can occur at too high a heating temperature. Deformation heat must be considered.
Long heating times lead to material losses from scaling and decarburization.
Slow cooling or step annealing after hot working prevents cracking.


After hot working, soft annealing is needed.
Alt.1 Ferritic annealing is performed at 770 C (1420 F). Annealing time 3 hours at temperature.
Hardness will be about 300 HV. Protective atmosphere or packing in cast iron mills can be
used to avoid decarburization.
Alt.2 Transformation annealing starts at 865 C (1410 F), and after that a slow cooling by
10 deg C/hour (20 deg F/hour) down to 700 C (1300 F). Hardness will be below 250 HV.
Protective atmosphere or packing to avoid decarburization.
Hardening can be performed in a vacuum, salt or open-air furnace. In a muffle furnace surface oxidation
and decarburization occurs.
This can be minimized but not totally prevented by the use of foils or protective paints.
Time at temperature 10 - 15 minutes. Heavier dimensions need more time.
Quenching should be fast from hardening temperature down to less than 800 C (1500F)
The cooling from 300 C down to room temperature can be slower.
The martensite formation can cause distortion if there are temperature gradients in the piece.

+deep cooling +deep cooling

Deep cooling gives increased hardness, especially in combination with a high hardening

Deep cooling is - 80 C minus ( - 144 F). Time, 10 minutes.
High temperature tempering reduces the corrosion resistance and should not be used for food
handling applications.
