Advantages of seamless cold drawn gas tube

- Sep 12, 2020-

  1. Improve surface roughness.

  2. Correct the roundness, the ellipse can be ≤0.01mm.

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

  4. There is a residual stress layer after processing to increase the fatigue strength by 30%.

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