| MaterialE | E235, E355 |
| Outer Diameter Range: | 4-120mm |
| Wall Thickness Range: | 0.5-15mm |
Delivery Condition
BK(+C): No heat treatment after the final cold drawig process.
Other Delivery Condition aviliable:
NBK(+N): After the final cold drawing operation the tubes are normalized in a controlled atmosphere.
GBK(+A): After the final cold drawing process the tubes are annealed in a controlled atmosphere.
BKW(+LC): After the final heat treatment there is a suitable drawing pass.
BKS(+SR): After the final cold drawing process there is a stress relieve heat treatment in a controlled atmosphere.
1. Smaller outer diameters;
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.
Surface Treatment
Surface treatment
Oil-dip;
As customer's requirements.
