Process Disadvantages: difficult to stabilize production quality control ; artificial cutting , single mixed ; easily lead to the ball surface fold ; heating defects, oxidation and decarbonization , grain coarsening , and even overheating, burning ; final forging temperature, and quenching inconsistent quality ; hardness of the product , hardenability and toughness can not guarantee stability ; low efficiency and high cost.
