Impact of Forging Process on Shaft Lifespan

Microstructure Optimization: Forging strengthens and refines grain structure through deformation, eliminates casting defects, increases material density, and enhances the fatigue and impact resistance of shaft components, significantly extending their service life.

Defect Control: Precision forging reduces surface cracks and internal inclusions, avoids stress concentration points, reduces the risk of fatigue crack initiation, and improves the reliability of the shaft under alternating loads.

Process Matching: Reasonable forging parameters ensure that the fiber structure is consistent with the stress direction, optimize load distribution, reduce local wear, and thereby improve overall lifespan.
