Cold Drawn Seamless Steel Tube , Precision Steel Tube For Cylinder System
Description:
Cold Drawn Seamless Steel Tube, also known as Precision Steel Tube for Cylinder System, is manufactured through a precise cold drawing process, ensuring high precision and consistent wall thickness. Ideal for applications requiring high mechanical strength and durability.
Material:
Main material: E235,E355
Other aviliable material: 10#,20#,45#,16Mn, ST30Al,ST35, ST37,ST37.4,ST45,ST52,ST52.4,E155,E195,E255, etc
OD: 4-120mm
WT: 0.5-15mm
Delivery Condition:
| Delivery Conditions | 1. BK (+C) | No heat treatment after last cold forming process. |
| 2. BKW (+LC) | After last heat treatment there is a light finishing pass (cold drawing) | |
| 3. BKS (+SR) | After the final cold forming process the tubes are stress relieve annealed. | |
| 4. GBK (+A) | After the final cold forming process the tubes are annealed in a controlled atmosphere. | |
| 5. NBK (+N) | After the final cold forming process the tubes are annealed above the upper transformation point in a controlled atmosphere. |
Advantage:
2. High precision can be done in small batch production;
3. Cold drawing finished products with high precision and good surface quality.
4. The transverse area of the steel tube is more complicated;
5. Steel pipe performance is superior, metal is more dense.
