|NBK(+N)||After the final cold drawing operation the tubes are normalized in a controlled atmosphere.|
After the final heat treatment there is a suitable drawing pass.
|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.|
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.
