Stainless Steel Tube Bright Annealing

Stainless Steel Tube Bright Annealing
+ Bright annealing tube

This is more commonly referred to as a Bright Annealing (BA) finish. Material with a No. 1 finish is cold rolled using highly polished rolls in contact with the steel surface. This smooths and brightens the surface.

Different from the tranditional process technique, we don't acid pickling at the last 2 steps, but directly bright annealing at the optimum temperature.

Advantage:
Guarantee the accurate thickness, smooth and balanced bright of both inside & outside surface
