The defects generated during the cleaning of forging usually include the following: Excessive pickling will loosen the forged surface. This defect is mainly caused by the high depth of acid and the long residence time of the forging in the pickling tank, or by the unclean cleaning of the forging surface and the residual acid on the forging surface. Corrosion crack: if there is large residual stres...
The reasons for insufficient hardness of forgings caused by improper post forging heat treatment process are: Quenching temperature is too low; Quenching heating time is too short; Tempering temperature is too high; Severe decarburization of forging surface caused by repeated heating; Unqualified chemical composition of steel, etc. Forging the reasons for the high hardness of forgings caused by im...
Defects caused by improper cooling after forging Cooling crack of forging parts: during the cooling process after forging, large thermal stress will be generated in the forging due to too fast cooling speed, or large structural stress may be caused by structural transformation. If these stresses exceed the strength limit of the forging, the forging will produce smooth and slender cooling cracks. N...
