Should stainless steel be passivated?
Jun 30, 2022
Stainless steel is increasingly widely used, mainly because of the characteristics of the series of materials for corrosion resistance, that is, the nature of rust, stainless steel manufacturing parts have a long life.
But the most easily misunderstood stainless steel is also its name ----- stainless steel. In fact, in the production and processing of stainless steel products, we should pay attention to anti-rust measures. That is to say, stainless steel in the finished product, after the surface rust treatment, after assembly, can think of processing, in order to prevent the occurrence of various corrosion accidents in the future use.
Where stainless steel parts, such as no plating or other coating requirements, generally in the pretreatment (including pickling black skin, polishing, etc.) after passivation treatment, can be used as finished products or assembled into parts. Facts show that stainless steel only after the final passivation treatment, to make the surface to maintain long-term passivation stability, thus, to improve the corrosion resistance.
