Stainless steel passivation

1. Improve the thermal stability of stainless steel in the environmental medium.

2. Prevent local corrosion of stainless steel

3. Passivation provides sufficient surface cleanliness

4. Remove heat treatment oxides on the surface of stainless steel

Finally add a point, before passivation treatment to pre-treatment, inappropriate metaphor, just like makeup, a layer of isolation, and then coated with other functional layers, there is a relationship and influence. Pretreatment to improve the surface state of stainless steel shot blasting, sand blasting, electrochemical polishing and chemical polishing can be passivation treatment.
