Tempering is a heat treatment process used to improve the mechanical properties and structure of steel. Tempered steel balls have the following characteristics:
1. Improve hardness: tempering can reduce the hardness of the steel ball, make it more ductile, reduce brittleness, and improve impact resistance.
2. Improve organizational structure: tempering can eliminate the residual stress in the steel ball, reduce internal defects, and improve the uniformity and stability of the material.
3. Adjust the performance of the steel ball: by controlling the tempering temperature and time, the mechanical properties of the steel ball can be adjusted to achieve the required strength, toughness and hardness.
4. Improve wear resistance: tempering can improve the grain structure of the steel ball, improve the wear resistance and corrosion resistance of the steel ball.
5. Reduce work hardening: tempering can reduce the work hardening of steel balls and improve the workability and plasticity of steel b…
