Product Description

Product information: 
 

1. Description:  Honing is a kind of machining technology. Through honing head, the inner hole of cold drawn pipe is processed by reciprocating high-speed grinding technology, so that the inner hole can meet the requirements of tolerance size and surface roughness that we need.
Honed tube is a kind of smooth bore steel tube used to manufacture hydraulic cylinder barrels that is the core part of a piece of hydraulic cylinder. 
2. Commodity:  42CrMo4 Precision Cold Drawn Honed Pipe
3. Size range:  Inside diameter: 25mm -500mm; Wall thickness: 2-50mm
4. Available steel grade: 
SAE/AISI:  SAE1020, SAE1026, SAE1045, SAE4130, SAE4140
DIN:  ST52, ST52.3, ST52.4
EN:  E355, C45E, 25CrMo4, 42CrMo4, CK45, S45C, E410, E470
GB:  20#, 45#, 16Mn, Q345B, Q345C, Q345D, Q345E, 25Mn, 27SiMn, 
5. Manufacture method:  Cold rolled, hydraulic cold drawn, hot rolled+deep hole boring
6. Delivery condition: 
BK BKW BKS GBK NBK Q+T
+C +LC +SR +A +N
Cold rolled Cold drawn Stress relieved Annealed Normalized Quenched+Tempered
7. Bore treatment:  Honing, skiving&roller burnishing
8. Bore roughness control:  Ra0.25um max or Ra0, 35um max for honed tubes, Ra0.25um max for skived&roller burnished tubes. 
9. End finish:  Plain ends with square cuts, free of burrs for honed tubes. Little bevelled ends for skived&roller burnished tubes. 
10. Standard export packing:  In bundles tied with steel strips. Internal &   external oil coating. Plastic caps on both ends. External packing by PVC bags and knit bags. 
11. Customized packing and marking  can be provided upon request. 
12. H8 tolerance: 
ID range Tolerance ID range Tolerance
18< d ≤30 +0/+0.033 180< d ≤250 +0/+0.072
30< d ≤50 +0/+0.039 250< d ≤300 +0/+0.081
50< d ≤80 +0/+0.046 300< d ≤315 +0/+0.081

120< d ≤180 +0/+0.063 400< d ≤500 +0/+0.097
13. Difference between honed tube and skived   &   roller burnished tube:  In hydraulic cylinder industry, there are 2 solutions for bore treatment: Honing, and skiving&roller burnishing. Honing or skiving&roller burnishing leads to different internal surface image, but both ensure good roughness.
