Table 4 Heat
Treatment
All stamped laminations or
machined parts must be annealed after fabrication to develop acceptable
magnetic properties. Anneal parts at 1400/1652°F (760/900°C) for 2 to 4 hours
in dry hydrogen or vacuum and cool at 144/540°F (80/300°C) per hour until 572°F
(300°C). All parts must be cleaned prior to heat treating.
Table 5 Workability
Hot Working
Hiperco 27 alloy can be forged
from a furnace temperature of 2150°F (1177°C). Time at temperature should be
approximately 1 hour per inch of thickness. Forging can be conducted down to a
temperature of 1700°F (927°C). After forging, items can be air cooled.
