The stainless steel quenched and tempered piston rod is rolled and mirror-polished to improve the surface corrosion resistance. The smoothness indicates the treatment, reduces the friction, and improves the fatigue strength of the quenched and tempered piston rod. Because of its many advantages, it is widely used in industry.
After the tempering piston rod is rolled, the surface roughness value is reduced, and the compounding property can be improved. At the same time, the friction damage to the sealing ring or the sealing member during the movement of the cylinder rod piston is reduced, and the overall service life of the oil cylinder is improved. The rolling process is a high-efficiency and high-quality process. The 160mm diameter doctor's cutting roller indenter (45 steel seamless steel pipe) is used as an example to show the rolling effect. After rolling, the surface roughness of the cylinder rod is reduced from Ra3.2 to 6.3um before the rolling of the building to Ra0.4 to 0.8um, the surface hardness of the cylinder rod is increased by about 30%, and the fatigue strength of the cylinder rod surface is increased by 25%.
The service life of the cylinder is increased by 2 to 3 times, and the rolling process is improved by about 15 times compared with the grinding process. The above data shows that the rolling process is highly efficient and can greatly improve the surface quality of the cylinder rodhttps://www.xhychromerod.com/
