Product Description

Precision Chrome Moly Alloy Steel Tube 4130 / 4140 / 30CrMo4 / 42CrMo4


Specification:
OD: 3mm-150mm
Wall thickness: 0.4mm-15mm
Tolerance of diameter: ≤±0.05mm；
Tolerance of W.T.: ≤±0.05mm；
Concentricity: ≤0.05mm
Straightness : 0.30mm/m
Note:
DN — Nominal Diameter
NPS —Nominal Pipe Size

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.
