Common materials for piston rods and their respective applications
Sep 10, 2018

The piston rod is a kind of shaft type with a large aspect ratio. It is mainly a connecting part that supports the work of the piston. Most of them are used in oil cylinders, cylinders, automobile manufacturing, hydraulic pneumatics, engineering machinery, printing machinery, textile machinery. In other products. At present, the piston rod is mainly made of 45# steel, 40Cr steel and stainless steel.

 

45# steel is a high-quality carbon structural steel. Piston rod products made of this material usually have good comprehensive mechanical properties. This material has a low hardness and is easy to cut. After quenching, the surface hardness can reach 45 to 52 HRC. 40Cr steel is also a commonly used material in the production of piston rods. It is not only a medium carbon quenched and tempered steel, but also a cold heading die steel. It has good comprehensive mechanical properties and is generally suitable for occasions with medium precision and high speed shaft parts.

 

Therefore, most of these types of piston rods are used for large impact forces or for heavy load transmissions to ensure sufficient working strength. Stainless steel is a kind of material used in the production of piston rods. The heat resistance, corrosion resistance and corrosion resistance of this material are relatively good. Through precision cold drawing, fine grinding, high precision polishing, etc. The technical specifications of the manufactured piston rod can reach a high standard.http://www.xhychromerod.com/
