Product Desciption

St52 E355 Ck45 AISI 1045 SAE 1045 Hard Chrome Plated and Turned Honed Seamless Carbon Steel Tube for Delivery Cylinder

PRODUCT INTRODUCTION
1. Description: 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: SAE1026 cold drawn seamless honed tube

3. Size range: 40mm*30mm-580mm*500mm

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	Q+T
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. Int&ext oil coating. End plastic caps. 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
80< d ≤120	+0/+0.054	315< d ≤400	+0/+0.089
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.
