Large-diameter alloy steel components are subjected to quenching and tempering, with a water-air alternating quenching method used instead of traditional oil quenching. This approach is environmentally friendly, cost-effective, and results in improved metallurgical structure and mechanical properties compared to oil quenching. The process not only reduces pollution but also enhances the overall quality of the parts, making it a preferred choice for high-performance applications. 1. Part Introduction A critical component in our company's product line is the 0A21074 half-shaft, made from 42CrMo alloy steel. It undergoes quenching and tempering treatment, with a specified hardness range of 269–321 HBW. The part’s design and structure are illustrated in Figure 1, showing its complex geometry and the need for precise heat treatment to meet performance requirements.
