Precision Seamless Steel Tubes Delivery Condition BKS Standard EN10305-1 Steel Round Pipe
Description
Precision seamless steel tube is a high precision steel tube after cold rolling or cold drawing
Main Date
| Standard | EN10305-1; DIN2391; DIN2445 |
| Material | E235, E355, St37.4, St52.4 |
| Outer Diameter Range: | 4-120mm |
| Wall Thickness Range: | 0.5-15mm |
Delivery Condition
BKS(+SR): After the final cold drawing process there is a stress relieve heat treatment in a controlled atmosphere.
Other Delivery Conditions
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.
BK(+C): No heat treatment after the final cold drawig process.
BKW(+LC): After the final heat treatment there is a suitable drawing pass.
Advantage
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.
