| HAYNES® 242® alloy is an is an age-hardenable
material which
combines excellent strength
and ductility in the aged
condition with good
fabricability in the annealed
condition. It is particularly
effective for strength-limited
applications up to 1300°F
(705°C), where its strength is as
much as double that for typical
solid-solution strengthened
alloys. It may be used at higher
temperatures, where its
solid-solution strength is
still excellent, but oxidation
resistance limits such
uses to about 1500-1600°F (815-870°C). |
