Bright annealed tubes in stainless steel grades and duplex steel grades are the main product line of Younglee Tubing, which is a high quality China precision stainless steel seamless tube manufacturer and supplier.

Detailed introduction of bright annealed tubes

Bright annealed stainless tubes are characterized by its inside and outside bright surfaces. Bright annealed tubes usually have stricter tolerances and are used in applications which requires high cleanness and high precision dimensions. To ensure the dimension accuracy, BA tubes are usually produced by cold rolling on high precision stainless steel tube cold rolling machines.
