WebProper placement of the parting line ensures that the principal grain flow direction within the forging will be parallel to the principal direction of service loading. The article reviews the mutual dependence of parting line and forging process. WebThe Forging Industry recognizes "L" sometimes described as "LG" or longitudinal, LT, long transverse and ST, short transverse grain directions. For rounds, you have just two general grain directions. Longitudinal "L" and radial "R". For biscuits, it becomes a bit more complicated as we add a tangential or "T" direction to the mix.

WebIntroduction: Forging is the process by which metal is heated and is shaped by plastic deformation by suitably applying compressive force. Usually the compressive force is in the form of hammer blows using a power hammer or a press. Forging refines the grain structure and improves physical properties of the metal. With proper design, the grain … WebForging refines the grain structure and improves physical properties of the metal.
