Annealed Pickling Stainless Steel Welded Tube

A249 welded tube should be annealed solution after welding, general Austenitic stainless steel heat treatment temperature from 1040 to 1150 degree Celsius, different grades have different annealing temperatures, this process can remove oxidation scale, plain grain structure and relieve stress, making tube soft and easy to fabricate, after annealing, ss tubes should be pickling in mixture of acid, removing scale and cleaning the surface, then passivation condition form a layer of oxidation film protecting tubes.

 

 

Bright Annealing Stainless Steel Welded Tube

Bright annealing (BA) finish is an another surface condition, it improve tube surface bright level and make surface more clean, a perfect additional requirement beside annealing passivation finishing.
