Is The Passivation Treatment Of Stainless Steel Screws Important?

In the process of production, stainless steel screws may be produced during processing during production during production, such as rough and turning. If it is not removed, the appearance of the screw surface will be affected or the screw will rust. Generally speaking, this surface treatment needs to be passivated to remove these surface impurities.
Passing the stainless steel screw can not only make the screw surface more smooth and shiny, but also improve the rust -proof ability and corrosion resistance of the screw. Due to different passivation treatment.
The salt fog test time is different, and some can exceed 24 hours, and some can exceed 1,000 hours. This requires the customer to actively tell how long the salt fog test will take, otherwise the stainless steel screw manufacturer will basically pass on the standard passivation.
Treating stainless steel screws according to standard passivation can basically only pass a 12 -hour salt mist test, and cannot reach longer. Therefore, when it is to be passivated, be sure to inform the screw manufacturers' own requirements, otherwise it will be different from their actual needs.
