Stainless steel piston rod adopts the advanced technology of rolling process
Sep 28, 2018

Stainless steel piston rods are mainly used in hydraulic and pneumatic, engineering machinery, automobile manufacturing and other fields. At present, the products are mainly processed by rolling process. Because surface surface residual stress is left on the surface layer, it helps the surface micro-crack closure and hinders erosion. The extension of the role. Thereby improving the surface corrosion resistance, and delaying the generation or expansion of fatigue cracks, and strengthening the fatigue strength of the stainless steel piston rod.


This is because in the process of processing by this process, a cold hardened layer can be formed on the hydraulic surface, which reduces the elastic and plastic deformation of the grinding contact surface, thereby improving the resistance of the stainless steel piston rod surface. Grindability while avoiding burns caused by grinding.


Not only that, the surface roughness of the obtained stainless steel piston rod is reduced, and the fitting performance is improved. More importantly, during the piston movement of the stainless steel piston rod in the cylinder, the friction damage to the seal ring or the seal may be effectively reduced, and the overall service life of the cylinder is improved.
