contactPassivation, generally associated with stainless steel, is a treatment method to protect the metal from corroding through—making the material “passive” to the surrounding environment. Passivation, perhaps counterintuitively, encourages corrosion to occur on the surface, creating a thin layer of a new, non-reactive chemical.
contact202068 · The surface treatment process of stainless steel tube is simple. However, in the actual processing process, pickling and passivation processing is quite difficult, mainly in the following two aspects: (1) stainless steel tube material can not be used to remove the surface oxide skin of parts by the conventional stainless steel derusting method.
