Shaft Hardening is a heat treatment process designed to increase the surface hardness and wear resistance of shafts used in various industrial applications. The process typically involves induction heating, where the shaft is rapidly heated to a specified temperature, followed by rapid cooling (quenching) to harden the surface. This process improves the shaft's resistance to wear, fatigue, and torsional stress. Shaft hardening is crucial for components in the automotive, aerospace, and manufacturing industries, where high strength and long-lasting performance are required for critical parts such as drive shafts, camshafts, and crankshafts.
