Compared with the casting, the shell body of the forged idler has a more uniform structure, better density, better strength integrity, better dimensional characteristics, and smaller dimensional error. The directional structure has higher performance in overall strength and application capability than the casting. High Strength Hot forging promotes the refinement of crystallization and grain, maxi...
