304 316 Stainless Steel Piston Rod For Hydraulic Cylinders And Pneumatic Cylinders
Stainless steel piston rod is mainly used for hydraulic and pneumatic, engineering machinery
and automobile manufacturing. The piston rod is processed by rolling. Due to the residual compressive
stress on the surface layer, it is helpful to close the small cracks on the surface and hinder the expansion
of erosion. So as to improve the corrosion resistance of the surface, delay the generation or expansion
of fatigue cracks, and improve the fatigue strength of the oil cylinder rod. Through rolling forming, a cold
work hardening layer is formed on the rolling surface, which reduces the elastic and plastic deformation
of the contact surface of the grinding pair, improves the wear resistance of the surface of the oil cylinder
rod, and avoids the burn caused by grinding. After rolling, the reduction of surface roughness can improve
the matching properties. At the same time, the friction damage to the seal ring or seal during the movement
of the oil cylinder rod piston is reduced, and the overall service life of the oil cylinder is improved.
