| Forged steel is considerably stronger and more
ductile than castings. S-N fatigue resistance
of forged steel is significantly better than the
cast materials. Forged steel is superior to castings
with respect to low cyclic fatigue.
Forgings need to be consistent from one piece
to another, without any defects such as porosity,
voids, or inclusions. This method creates components
that have a high ratio of strength to weight.
These components are often used in the design
of aircraft frame members.
Seamless rolled rings offer superior integrity
for demanding engineering applications. Seamless
rolled rings also provide a cost effective alternative
to fabricating rings from plate.
