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...
