Date：2023-09-25 14:46:24 Hits：264 From：Ningbo Zhenhai Bright Heat Treatment Plant

Heat treatment has multiple uses, including:

1) Improve the mechanical properties of materials, including hardness, tensile strength, seismic resistance, ductility, and corrosion resistance.

2) Improve machinability and reduce brittleness.

3) Used to eliminate internal stress generated by metal during hot or cold working processes.

4) Change the granularity or refine it.

5) To increase magnetic and electrical properties.

6) To increase corrosion resistance and wear resistance.

7) To improve the surface hardness of the material.

8) Increase the fatigue limit of small and medium-sized parts such as gears, piston pins, and shafts.

9) Provide a clean, bright, and pleasant appearance to the hardened surface.

10) Obtain a hard core through surface hardening.

11) Heat treatment can improve the hardening performance of steel, enabling it to cut other metals.

12) Promote structural uniformity.
