Process measures and corrosion resistance of stainless steel piston rod
Stainless steel piston rods are mainly used for hydraulic starting, engineering machinery, automotive manufacturing piston rods, plastic machinery guide columns, packaging machinery, printing machinery roller shafts, textile machinery, conveying machinery axis, and linear motion linear axis during use.
Stainless steel piston rods are mainly processed by rolling. During operation, residual compressive stress is left on the surface of the indicated layer, which helps to seal small surface cracks and hinder the propagation of erosion. Thereby improving the surface corrosion resistance and delaying the occurrence and expansion of fatigue cracks, thus enhancing the fatigue strength of the oil cylinder rod.
The stainless steel piston rod is formed by rolling, forming a cold work hardening layer on the rolling surface, reducing the elastic and plastic deformation of the grinding contact surface, thereby improving the wear resistance of the cylinder rod surface and avoiding burns caused by grinding. After rolling, the reduction of surface roughness value can improve the fitting properties. At the same time, it reduces the friction damage to the sealing ring or seal during the movement of the cylinder rod piston, and improves the overall service life of the cylinder.
The rolling process of stainless steel piston rod is a high-quality process measure. After rolling, the surface roughness of the oil cylinder rod decreases from Ra3.2-6.3um before rolling to Ra0.4-0.8um, the surface hardness of the oil cylinder rod increases by about 30%, and the surface fatigue strength of the oil cylinder rod increases by 25%. The service life of the oil cylinder is increased by 2-3 times, and the efficiency of the rolling process is about 15 times higher than that of the grinding process. The above data indicates that the rolling process can improve the surface quality of the oil cylinder rod.
In order to complete the operation of the product, we should clean the stainless steel piston rod, which is also to have a high-quality stainless steel piston rod. Simply put, we can use soap or warm water for washing. If this method cannot completely clean, then we can naturally use other methods, such as using professional cleaning agents, etc. No matter what method you use to operate, our focus is on its effectiveness. If the effect is not good, it will naturally be of no use to us.
