Bright Seamless Tube
Bright seamless tube is a cold-drawn or cold-rolled seamless stainless steel tube with bright surface finish achieved by bright annealing or pickling. It features smooth surface, uniform wall thickness and good mechanical properties, and is widely used in general engineering, mechanical parts, fluid transport and decorative applications.
