Detail
Forged Neck is accomplished in 4 stages.
The Forging Process
In this process, the steel is first fired as red hot ingot, next huge hammers com-
pact and orient the grain structure into a rough shape of the part, subsequent
hits form the part into its final shape, after which it is machined and heat treated
which results in increased strength and resistance to wear.
