Forging
is a process by which a metal is heated and given a desired shape by an
application of an appropriate compressive force, typically applied using
a power hammer or a press.
The
forging development creates a sophisticated structure that improves the
physical properties of the metal. A proper design can go a long way in
orienting the grain flow in the direction of the main stresses during
the actual use of the part.
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.
