FAQ:
Q1:What is the stainless steel pneumatic cylinder hard chrome rods?
A:Stainless steel hard chrome rods are mainly used for hydraulic and pneumatic piston rods for engineering machinery, automobile manufacturing, guide posts for plastic machinery, rollers for packaging machinery, printing machinery, textile machinery, axis for conveying machinery, and linear optical axis for linear motion. . The piston rod is processed by rolling. Because the surface layer has residual surface stress, it helps to close the micro cracks on the surface and hinder the expansion of corrosion.
Q2:What are the characteristics of stainless steel pneumatic cylinder piston rod?
A:The stainless steel pneumatic cylinder piston rod is processed by rolling. Because the surface layer has residual surface stress, it helps to close the surface micro cracks and hinder the expansion of corrosion.
Thereby improving the surface corrosion resistance, and can delay the generation or expansion of fatigue cracks, thereby improving the fatigue strength of the cylinder rod. Through roll forming, a cold work hardened layer is formed on the rolled surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair, thereby improving the wear resistance of the cylinder rod surface and avoiding burns caused by grinding. After rolling, the surface roughness value is reduced, which can improve the mating properties. At the same time, the friction damage to the sealing ring or the sealing element during the movement of the cylinder rod piston is reduced, and the overall service life of the pneumatic cylinder is improved.
Q3:What are the advantages of 304 stainless steel piston rod
A:Stainless steel 304 is a material used in the production of piston rods. It is resistant to weak corrosive media such as air, steam, and water. Commonly used materials are 304, 316. The weldability, polishability, heat resistance, corrosion resistance, and corrosion resistance of these materials are relatively good. Through precision cold drawing, precision grinding,high precision polishing and other processes, the stainless steel piston rod manufactured by the All technical indicators meet and exceed national standards, so they are often used in oil cylinders,air cylinders,and shock absorbers.
Q4:What is the rolling process of the stainless steel pneumatic cylinder piston rod?

Q5:What are the characteristics of the stainless steel piston rod of the pneumatic cylinder?
A:1.Excellent corrosion resistance, good corrosion resistance in the production process of pulp and paper. Moreover, 304 stainless steel is also resistant to corrosion by the ocean and corrosive industrial atmosphere.
2.In the high temperature environment, 304 stainless steel has good oxidation resistance. Under high temperature conditions, when the concentration of sulfuric acid is lower than 15% and higher than 85%, 304 stainless steel has a wide range of uses.
