Carbon steel balances durability, hardness, and wear resistance using formability, weldability, and durability; Chrome plating provides corrosion resistance along with an Extremely reflective look High precision tolerances, which ensures when used to make hydraulic piston rod, it can fit the cylinder precisely. Good Hardness: the surface hardness attaining HV850 minimal and upward, which not only help improve wear resistance but also help extend the life span of these chrome plated rods, thereby helping the consumer save the cost. High performance of strength: The yield strength of chrome plated bars can be 75000 psi up to 100000 psi. Besides  chrome plated rods ,  Datong Hydraulic  also produce and supply induction hardened chrome plated cylinder rods. honed tube , hydraulic cylinder barrel ,  hollow chrome bar Want to buy chrome plate rods?

  The   piston rod   can be used for hydraulic starting, the piston rod processing requirements are very high. Therefore, the quality of the hydraulic cylinder mainly depends on the quality of the piston rod, which is the connecting part supporting the work done by the piston, and most of which is used in the  cylinder . Cylinder motion actuator is a kind of moving part with high technical requirements. The quality of precision piston rod directly affects the life and reliability of the whole product. Although from the point of view of design, piston rod is not considered to be affected by radial force, but it is directly restricted by the actual structure in use, and the piston rod is inevitably affected by radial external force. The machining length of precision piston rod should increase its guiding function, increase bearing surface area, reduce wear and improve the service life of hydraulic cylinder, and the quality of hydraulic cylinder mainly depends on the qu...

Ck45  induction hardened chrome plated bar  is used extensively by the hydraulic and pneumatic industries, for those applications utilising its high surface hardness and excellent resistance to surface impact. Induction hardened: Induction hardened is a form of heat treatment in which a metal part is heated by induction heating. Induction hardening of piston rods in hydraulic cylinders is performed in order to increase the resistance to damage from external impact in applications where there is risk for them. The hardness after this heat treatment is HRC 40 to 45. Surface hardness:  min. 900 HV0.1 (66 HRC) the surface hardness in the induction-hardened zone immediately beneath the chrome layer is min. 55 HRC (HV 595). Hardening depth:  0.75 – 4.0mm depending on the diameter. Other hardening depths can be supplied by special arrangement. Corrosion resistance:  min. 120 – 200 hours in Neutral Salt Spray testing according to ISO 9227 standard or its equivalents, co...

The production procedure of the  cylinder chrome rod : Datong Hydraulic   will check the material of cylinder chrome rod; then do a precision grinding process, and the surface undergoes a hard chrome surface treatment. The surface precision accuracy reaches to f8. Our chemical solution adopts HEEF 25RS from the United States, which assure our cylinder chrome rod a perfect chrome layer. Material of hard chrome plated bar: The hard chrome rod material includes JIS S45C, SAE1045, DIN CK45, JIS G4105, SCM440, SAE4140, and DIN 42CrMo4. Also, we provide stainless cylinder chrome rod, such as SUS304, SUS316 and SUS410. Other material of cylinder chrome rod can be supplied upon request. Treatment of cylinder chrome rod: treatment of induction hardened, quenched and tempered can be supplied upon request. Application of hydraulic cylinder chrome rod: The cylinder chrome rod is used for the hydraulic cylinder, such as the hydraulic mechanism adopted on the heavy machinery, construction e...

1. After the  4140 hard chrome plated bar  piston is processed, the water pressure experiment should be stopped, and the water pressure is generally L 5 times the maximum working pressure. 2. When the chromium-plated rod piston shows cracks, it should generally be scrapped; the cylindrical surface of the piston is worn due to the friction of the piston ring, which is usually not repaired; when the diameter of the cylinder bore is increased, it needs to be selected according to the increased diameter New bracket; repair only when the chrome-plated rod piston is worn or the chrome-plated rod piston ring groove and cylindrical piston pin hole are worn. 3. When the chrome-plated rod piston is scratched or scratched, you can first use a file to file the abrasion and nodules carefully, and then use a whetstone to quietly polish and lubricate.
