Chrome steel rod use and corrosion resistance

- Aug 30, 2019-

If the chrome steel rod is made of inferior steel during the production process, it will directly affect the service life of the product to a certain extent, and it is very prone to accidents.


Piston rod tolerance size effect


1 Large tolerances affect normal installation.


2 The tolerance is too small, the machine can not operate normally, and affect the life of the equipment.


The piston rod can improve the hardness, wear resistance and corrosion resistance of the metal surface. The surface plating layer of the product is not thick enough, which may cause the product to rust and the surface hardness to be unsatisfactory. The requirements for the smoothness and roughness of the piston rod surface. The rough surface of the piston rod not only affects the service life of the product, but also directly affects the plating quality, causing the plating layer to peel off or rust prematurely, thus losing surface protection. Ultra-mirror products can be produced according to customer needs.


The piston rod is rolled to improve the surface corrosion resistance and delay the generation or expansion of fatigue cracks, thereby improving the fatigue strength of the cylinder rod. By rolling forming, the rolling surface forms a cold hardening layer, which reduces 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 surface roughness value is reduced to improve the compounding property. 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 an efficient and high quality process.
