Application: 1. High dimensional accuracy, the tolerance of inner and outer
diameter size can be accurate to within 0.05mm, better tolerance
can controled wihthin 0.025mm. Precision H8-H10 2. Good surface smoothness finish; 3. Good cleanliness, inside and outside surface no oxide layer 4. Can withstand high pressure, cold bending, flaring flattening,
without cracking/ wrinkled 5. Excellent overall performance, can make a variety of complex
deformation and machining.
Application: For mechanical engineering For mechanical and pressure use,and also for transporting
steam,water,gas and etc. ASTM A519 specification covers for several grades of carbon and
alloy steel mechanical tubing, either hot-finished or
cold-finished. 1.Auto parts ;Gas spring;Motor housing, dc motor;Industrial
processing: machine parts, bearing sleeve, Hydraulic cylinder ,air
cylinder;Other: electrical gas transmission, water generation fluid
pipeline, etc.
