Whether forged components require tempering treatment during manufacturing depends on their specific application requirements and performance needs. Quenching and tempering is a heat treatment process aimed at improving the comprehensive mechanical properties of steel materials. By subjecting steel components to quenching followed by high-temperature tempering, the process achieves a good balance between strength and toughness. For certain critical structural components, especially those operating under alternating loads, quenching and tempering is essential as it provides high strength, excellent toughness, plasticity, and machinability.

However, not all forgings require tempering treatment. For example, some forgings may meet performance requirements through normalizing treatment immediately after forging, especially for components with lower performance requirements. Additionally, some customers may believe that the hardness of forged components is sufficient and tempering treatment is unnecessary, but this approach overlooks factors such as microstructural changes and stress relief.
