ASTM A519 SAE 1045 Cold Drawn Seamless Honed Steel Tubing for Hydraulic Cylinder

Portion I: Product INTRODUCTION
one. Description: 
Honed tube is a kind of smooth bore steel tube used to manufacture hydraulic cylinder barrels that is the main part of a piece of hydraulic cylinder. 

two. Commodity: ASTM A519 SAE 1045 cold drawn seamless honed metal tubing for hydraulic cylinder

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

4. Obtainable metal grade: 

SAE/AISI:  SAE1571, SAE1026, SAE1045, SAE4130, SAE4140
DIN:  ST52, ST52.three, ST52.four
EN:  E355, C45E, 25CrMo4, 42CrMo4, CK45, S45C, E410, E470
GB:  twenty#, forty five#, 16Mn, Q345B, Q345C, Q345D, Q345E, 25Mn, 27SiMn, 

five. Manufacture strategy: Chilly rolled, hydraulic chilly drawn, hot rolled+deep gap uninteresting

6. Supply condition: 

BK BKW BKS GBK NBK Q+T
+C +LC +SR +A +N
Chilly rolled Cold drawn Anxiety relieved Annealed Normalized Quenched+Tempered

7. Bore treatment: Honing, skiving&roller burnishing

eight. Bore roughness management: Ra0.25um max or Ra0, 35um max for honed tubes, Ra0.25um max for skived&roller burnished tubes. 

nine. Conclude finish: Simple ends with sq. cuts, free of burrs for honed tubes. Small bevelled finishes for skived&roller burnished tubes. 

10. CZPT export packing: In bundles tied with steel strips. Int&ext oil coating. End plastic caps. External packing by PVC baggage and knit baggage. 

11. CZPTized packing and marking can be offered upon ask for. 

12. H8 tolerance:

120< d ≤180 +/+.063 400< d ≤500 +/+.097

thirteen. Difference amongst honed tube and skived&roller burnished tube: In hydraulic cylinder sector, there are 2 solutions for bore therapy: Honing, and skiving&roller burnishing. Honing or skiving&roller burnishing prospects to diverse internal surface area image, but equally guarantee good roughness.

Part II: Often Requested Inquiries
one. MOQ: 
CZPTly Min Purchase Amount can be two-three tons/dimensions for tubes with OD beneath 250mm, and 10 tons/dimension for tubes with OD over 250mm. Sometimes, it depends on metal grade you want. If you need to have specific grade like E410, E470 or alloy steel tube, MOQ need to be ten tons/dimension at minimum. 
two. Shipping and delivery Time: CZPTly, our shipping time for honed tubes is all around 40-60 days depending on the measurements and quantities. It will consider us 15-thirty times to get uncooked substance. For illustration, if you need 3 tons of little dimension honed tubes 50mm*40mm with roughness of Ra0.25um max, it will take us at least 30 times to hone this dimensions. 
3. Guarantee&Guarantee: Guarantee&ensure time period is 6 months given that we deliver the tubes, and we are not responsible for good quality difficulty brought on by incorrect unloading or storage right after shipment. We welcome customer’s inspection prior to shipment. 
four. Payment Method: We acknowledge payment technique like T/T, L/C, or D/P, but it depends on our investigation about clients. We have a solution to appraise the credit history of consumers from all in excess of the entire world, and time and sum of D/P we can launch is decided by the evaluation. 
five. High quality Handle: ninety% of the tubes are created from very hot rolled seamless pipes. So, high quality of raw materials decided top quality of finished tubes. We acquire raw substance from steady suppliers who are leading steel mills, and we examine the uncooked substance as per the specifications. Throughout our manufacturing treatment, there is inspection and top quality manage in every single stage. 

Component III: Business INTRODUCTION
We are a manufacturer of cold drawn, chilly rolled, and hydraulic cold drawn metal tubes with OD upto 356mm because 2002. Masking an area of about 32000M2, we have twelve common workshops with 2 hydraulic cold drawing benches, 4 chain cold drawing benches, and 2 ERW mills. Our services covers all the creation processes from pickling, cold drawing, heat managing, saw chopping, straightening, inspection, packing to more machining &turning, chilly drawing die fabrication, and products repairation&upkeep.
