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,

6. Delivery condition: 
BKBKWBKSGBKNBKQ+T
+C+LC+SR+A+N
Cold rolledCold drawnStress relievedAnnealedNormalizedQuenched+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:
