Advantage of Precision Seamless Steel Tubes
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.
|Cold drawn/ hard||+C||No heat treatment after the final cold drawig process.|
|Cold drawn/ soft||+LC||No heat treatment after the final cold drawig process.|
|Cold draw and stress relieved||+SR||After the final cold drawing process there is a stress relieve heat treatment in a controlled atmosphere.|
|Annealed||+A||After the final cold drawing process the tubes are annealed in a controlled atmosphere.|
|Normalized||+N||After the final cold drawing operation the tubes are normalized in a controlled atmosphere.|
