Annealed and pickled stainless steel tubes are the most common seen stainless tubes used in industrial applications and have the widest usage. This product can simultaneously maintain the same production capacity and production cost as conventional annealing pickling. By the technique of annealing pickling, the generation and growth of oxides are further prevented by using a non-oxidizing atmosphere, and the residual iron oxide scale is removed and the passivated surface is recovered by dissolving the reaction layer of the inner layer. Compared to chemical processing, this product reduces the adverse effects of chemicals on the environment.
Remove the oxide layer formed on the surface
Reduce the oxidation of stainless steel in the annealing section,
Save on the cost of pickling
Reduce the amount of waste liquid processed.
The surface is passivated to impart corrosion resistance to the steel sheet
