BA stainless steel tubes
Bright annealed stainless tubes, compared to pickled tubes, are characterized by its bright surfaces, both inside and outside. Bright annealed tubes usually have stricter tolerances and are used in environment that demands high cleanness and high precision. To ensure that, BA tubes are usually rolled out on high precision cold rolling machines.
