Everyone should know that the main manufacturing process of precision piston rods is rolling processing. The rolling processing method can reserve residual stress on the surface of the product, which helps to seal small cracks on the surface of the product and expand the role of erosion barrier. The following editor will introduce the heat treatment processing method of precision piston rods:
1. After heat treatment, the brittleness of the raw material will decrease to a very low level, increasing the toughness of the product in the raw material.
2. After heat treatment processing, the hardness and wear resistance of the product surface are increased, reducing the occurrence of cracks in the product due to quenching.
3. After heat treatment, the precision piston rod greatly increases the toughness brought by impact under low temperature conditions, which increases the quality of raw materials in different aspects and increases the entire service life of the product.
