Quality requirements for steel pipes of hydraulic cylinders

Hydraulic cylinder steel pipe is a kind of high-precision steel pipe material after cold drawing or hot rolling. The hydraulic cylinder steel pipe has the advantages of no oxide layer on the inner and outer walls of the hydraulic cylinder steel pipe, no leakage of the hydraulic cylinder steel pipe under high pressure, high precision and smoothness of the hydraulic cylinder steel pipe, no deformation in cold bending, flaring, flattening and no cracks of the hydraulic cylinder steel pipe, so the hydraulic cylinder steel pipe is mainly used to produce pneumatic or hydraulic components, such as cylinders or hydraulic cylinders. The hydraulic cylinder steel pipe mainly contains rare metals manganese Mn, sulfur s, phosphorus P and chromium CR.

Characteristics of hydraulic cylinder steel pipe

1. The surface roughness can basically achieve RA ≤ 0.08mm.

2. The corrected roundness and ovality of steel pipe can be ≤ 0.01mm.

3. Improve the surface hardness, eliminate the stress deformation, and increase the hardness HV ≥ 4 °.

4. There is residual stress layer after processing, and the fatigue strength is increased by 30%.

5. Improve the matching quality, reduce wear and prolong the service life of parts, but the processing cost of parts is reduced.
