The Bright Annealing process in Vinmay is performed in a controlled atmosphere containing inert hydrogen gas at 1040℃. Annealing is a typically used to reduce hardness , increase ductility and eliminate internal stresses.While the controlled atmosphere reduces the surface oxidation to a minimum which results in a brighter surface and a much thinner oxide layer. Picking is not needed after bright annealing since the oxidation is minimal. Since there is no pickling , the surface of stainless steel sanitary tube is much smoother which results in better resistance to pitting corrosion.
After the process, bright annealed finish has a bright, reflective appearance, but may have some cloudiness slightly different from MF (Mill Finish)
Vinmay has full set of online inside bead removing equipment,bringing smooth surface for inner weld seam to meet clean purpose, and controlling the height of weld seam for precision request. It's an important process for pipes of fluid field or food industry.
