|
FORGING
|
1900-2000° F
|
In air.
|
Heat slowly to maximum temperature. Do not work below approximately 1500°
F. Normalizing is recommended.
|
|
ANNEALING
|
1550-1600° F
|
Cool slowly at a rate of 25° F per hour to 1000° F.
|
|
|
STRESS RELIEVING
|
|
|
Stress relieve after rough machining
|
|
PREHEATING
|
1200-1250° F
|
|
Preheat time in furnace is ¾ Hr. per inch of thickness.
|
|
HARDENING
|
1400-1450° F
|
In warm oil.
|
A neutral or slightly oxidizing atmosphere is desirable. Temper immediately
after hardening. Allow to cool to 125-150° F before tempering.
|
|
TEMPERING
|
(See Chart)
|
|
Temper for 1 Hr. per inch of thickness with a minimum of 2 Hrs. Recommended
temperature is 300-750° F.
