What is Stainless Steel Seamless Tube?

A SS Seamless Tube is a Hollow Cylindrical Pipe without any welded joints. It is produced through cold drawing or cold rolling procedures. Herein, a solid stainless steel billet is pushed through a die to form the desired tube shape. The seamless nature of the tube reduces the risk of leaks and enhances its strength.



Cold vs Hot Finished Stainless Steel Tubing

  • Stainless Steel Tube Manufacturers produce cold finished tubes by drawing the stainless steel through a die at room temperature. Hot-finished tubing is produced by heating the stainless steel billet to high temperatures and then passing it through rolling mills.
  • The cold drawn process enhances the mechanical properties of the stainless steel. Thus, cold finished ss tubes have higher strength & hardness than the hot finished ones.
  • Stainless steel CF tubes have a smoother and more consistent surface finish. HF tubes may have a rougher surface.
  • SS CF tubes are used in more critical applications than HF ones.
