HAYNES® 214® alloy is normally final
solution heat-treated at 2000°F
(1095°C) for a time commensurate
with section thickness. Solution
heat-treating can be performed at
temperatures as low as about 1950°F (1065°C), but resulting material
properties will be altered accordingly.
Annealing during fabrication can be
performed at even lower temperatures,
but a final, subsequent solution heat
treatment is needed to produce optimum structure and properties.
It is imperative that components
be cooled as rapidly as possible
from intermediate and final anneal
operations in order to achieve
maximum ductility.
