ASTM A269 TP316L / UNS S31603 / 1.4404 Bright Annealed Stainless Steel Tube

ASTM A269 TP316L / UNS S31603 / 1.4404 Bright Annealed Stainless Steel Tube

Bright annealed seamless tube is charactrized by high quality smooth, bright and clean inside and outside surface, free of oil and grease, precision dimension tolerances, high strength and high corrosion resistance.

YUHONG GROUP supplies a wide range of bright annealed tubing in stainless steel, duplex / super duplex stainless steel grades. If you have such demands, please feel free to send us inquiry.

Bright annealing is an annealing process performed in a vacuum or a controlled atmosphere containing inert gases (such as hydrogen). This controlled atmosphere reduces the surface oxidation to a minimum which results in a brighter surface and a much thinner oxide layer. Pickling is not needed after bright annealing since the oxidation is minimal. Since there is no pickling, the surface is much smoother which results in better resistance to pitting corrosion.
