NOTES |
FORGING |
1700-1900° F |
In air. |
Do not work below approximately 1400° F on intricate and large sizes. Normalizing is recommended. |
ANNEALING |
1400-1450° F |
Cool slowly in the furnace at a maximum rate of 50° F per hours. Air cool. |
Hold one hour at heat. Tools should be packed in a container to reduce decarburization. |
STRESS RELIEVING |
1000-1250° F |
Cool slowly in air. |
Stress relieve after rough machining |
PREHEATING |
1200-1250° F |
|
Preheat time in furnace is ¾ Hr. per inch of thickness. |
HARDENING |
1425-1500° F |
In water or in a brine solution. |
Soak time is 10 minutes per inch of thickness. Minimum of 15 minutes. |
TEMPERING |
(See Chart) |
|
Temper immediately after hardening and quenching. Time will range from 1 to 3 Hrs. Recommended temperature is 350-550° F. |
