Secrets to Enhancing Forged Shaft Performance

Secrets to Enhancing Forged Shaft Performance:
Material selection is fundamental. Prioritize alloy steel (such as 40Cr, 42CrMo) or carbon steel (such as 45 steel) and enhance strength and wear resistance through heat treatment processes like quenching and tempering. For example, 40Cr can achieve a hardness of HRC52 after quenching and tempering, significantly enhancing fatigue resistance.

Process optimization is key. Employ multi-directional die forging or radial forging techniques to achieve uniform material deformation and reduce internal defects. For example, radial forging achieves a precision of ±0.5mm for outer diameter and ±0.1mm for inner diameter, suitable for high-precision shaft parts.

Quality inspection is a guarantee. Strictly control the quality through metallographic examination, mechanical property testing, and other methods to ensure uniform structure and no cracks in the forgings. For example, YTO Group Corporation in Henan significantly improved the internal quality of forgings by optimizing process parameters.
