NOTES |
FORGING |
1700-1900° F |
In air. |
Heat slowly to maximum temperature. Forging should begin as soon as the section is uniformly heated through. |
ANNEALING |
1400-1450° F |
Cool slowly in the furnace at a maximum rate of 50° F per hours.. |
Protect against surface decarburization by pack-annealing. Hold at temperature for 1 hour. |
STRESS RELIEVING |
1200-1250° 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 |
1375-1450° F |
In water or in a brine solution. |
Small tools or parts may be heated in molten lead or in a salt bath. Soak time is 10 minutes per inch of thickness. Minimum of 30 minutes. |
TEMPERING |
(See Chart) |
|
Temper immediately after hardening and quenching. Recommended temperature is 350-550° F. |
