Before, we introduced some basic knowledge about drawing shaped seamless steel tube, but we have have not introduced some of it’s important properties that many people still do not know. Now, we will introduce the characteristics and performance of the drawing shaped seamless steel tube.

First of all, cold drawn seamless steel tube cold rolling steel section allows local buckling which can make full use of bar buckling bearing capacity; and hot rolled steel does not allow the local buckling of cross section.

Secondly, the reasons for the residual stress of hot rolled and cold rolled steel are different, so the distribution of the cross section is very different.


Then, the residual cold-formed steel section stress distribution is curved, and hot rolled steel or steel welding section on the residual stress distribution is thin.

Finally, the free torsion rigidity of hot rolled steel is higher than that of cold rolled steel. Cold drawn seamless steel tube material: 10# 20# 45# Q345B general (16Mn 20CrMo)

Cold drawn seamless steel tube precision is higher than ordinary drawing steel surface is smooth, cost savings, machinery industry is preferred. At the same time, drawing shaped seamless steel tube is one of the big US Peng's main product, if you need, you can contact us to order!
