“淬火-回火弹簧钢丝用热轧盘条（英文版）”介绍

Quenched and tempered spring wire made from hot-rolled coil is a specialized steel product that undergoes a specific heat treatment process to achieve superior mechanical properties. This process begins with the hot rolling of the steel, which is then quenched to cool it rapidly and form a hard martensitic structure. Following this, the steel is tempered by reheating to a lower temperature, allowing the martensite to decompose into a mixture of ferrite and carbide, thus reducing its brittleness and increasing toughness while maintaining high strength and hardness.

The end result is a wire that exhibits excellent elasticity and fatigue resistance, key factors for its use in manufacturing springs for various applications such as automotive suspension systems, machinery vibration control devices, and other industrial equipment requiring resilient metal components. The quenching and tempering process refines the steel's microstructure, enhancing its ability to withstand repeated stress without deformation or fracture. This makes the material ideally suited for high-performance spring applications where consistency and reliability are paramount.
