Compared with forged steel shaft and cast steel shaft, which one is more suitable for withstanding high load and frequent operation?

Forged finished steel shafts are generally more suitable for high load-bearing and frequent operation applications compared to cast steel shafts. Forged finished steel shafts are produced by heating a steel billet to an appropriate temperature and then forging it into shape, followed by fine processing and surface treatment to obtain the final shape and size. In contrast, cast steel shafts are produced by pouring molten steel into a mold to cool and solidify. The significant differences in their manufacturing processes and material structures lead to different performance characteristics in use.

Forged finished steel shafts undergo a significant improvement in their grain structure during the forging process, resulting in denser and more uniform grains. This effectively enhances the strength, toughness, and wear resistance of the shaft. Simultaneously, the forging process eliminates internal defects and pores, thereby improving the overall quality and reliability of the shaft. Consequently, forged finished steel shafts are better equipped to withstand the mechanical stresses induced by high loads and frequent operation, maintaining stable performance over an extended period.

Forged finished steel shafts can achieve highly precise geometrical shapes and dimensional accuracy after fine machining, which is realized through numerical control machining equipment and precision measuring tools. This high-precision machining ensures the stability and reliability of the shaft during installation and operation, preventing assembly problems or poor mechanical fit caused by dimensional deviations, further improving the working efficiency and safety of the equipment.
