Seamless Tube for Auto Parts
In the automotive industry, seamless tubes play a crucial role in ensuring the reliable and efficient operation of various auto parts.The smooth surface of seamless tubes is a key advantage
Carbon steel seamless tubes, especially those with low carbon content like 10# and 20# steel, are widely used due to their good formability and cost - effectiveness. They are suitable for components that require moderate strength.
Seamless tubes are integral to the automotive industry, providing the strength, precision, and durability required for a wide range of auto parts. Their diverse material options and applications make them a cornerstone of modern vehicle design and manufacturing.

| Cold drawn / soft | After last heat treatment there is a light finishing pass (cold drawing). |
| Cold drawn (+SR) | After the final cold forming process the tubes are stress relieve annealed. |
| GBK (+A) | After the final cold forming process the tubes are annealed in a controlled atmosphere. |
| NBK (+N) | After the final cold forming process the tubes are annealed above the upper transformation point in a controlled atmosphere. |
Seamless Steel Pipe Manufacturing Process
The round steel bar is used to produce seamless pipe. After heating the bar to a high temperature, a probe is put into the bar to produce a hole. The cylinder is then moved to rollers that shape it to the required diameter and wall thickness.
