How do we cold treat high-precision cold drawn tubes?

 
  High precision cold drawn tubeIt will cause the residual austenite inside to transform into martensite, but it is impossible to completely transform. After experiments, it can be found that there will basically be about 2% residue. Then at this time, the residual austenite needs to be retained, which can have a buffering effect.
       After the cold treatment is completed, it is also necessary to take out the high-precision cold drawn tube and put it in hot water for heating treatment. This can reduce the cold treatment stress by about 40%. After the gradual temperature rise, it should also be tempered and cold treated as soon as possible. Most of it can be reduced as soon as possible, and it is also It can reduce the occurrence of cracks, thereby obtaining stable performance, so that high-precision cold-drawn pipes will not deform during later use, and it is also convenient for storage in daily life. These are actually some preventive measures for cold treatment. If you can do it well, it will not have a big impact.
