A bright polish finish with the polishing pattern running circumferentially with a range of finishing grits is available. A high mirror finish can also be achieved.
Annealing after welding or drawing increases corrosion resistance and softens the tube for severe manipulation such as bending, expanding and forming. STM anneals in a reducing atmosphere which maintains the bright appearance of the stainless steel.
By cold drawing annealed, welded or cold worked tube fine dimensional tolerance are achieved. Drawn tube has excellent uniformity of wall thickness and concentricity, uniform grain structure and hardness.
