Subconsciously, we all think that stainless steel screws will not rust, in fact, in bad environment, stainless steel screws will be corroded after rust,

So rust is also a more common situation, but when we use stainless steel screws, most of them are used indoors or on some electrical equipment,

The working environment is better, there is no pollution of sea water and strong acid atmosphere, and the probability of rust is relatively low, so the phenomenon of rust will be less.

We can only say that the corrosion resistance of stainless steel screws is particularly good, it has a strong corrosion resistance to the general atmosphere environment, but in the coastal zone use, a long time still rust.

It is this different use environment, requires the necessary understanding of some basic performance of stainless steel screws, in order to reasonable and effective use of stainless steel screws.

For different temperatures and conditions, we can choose different stainless steel screws, such as 304 stainless steel screws or 316 stainless steel screws.

How to prevent corrosion of stainless steel screws?

Standard parts manufacturers summary: stainless steel screws anti-corrosion measures;

1, the selection of qualified stainless steel screws, structural design to avoid the formation of gaps, to avoid causing easy to produce surface deposition geometric conditions;

2, the stainless steel screw and Cl- containing aqueous solution for effective isolation, can not avoid the gap, through the stainless steel screw corrosion prevention effect of understanding, should be used to weld or fill the gap, so that the aqueous solution can not enter;

3, the use of high chromium, high molybdenum stainless steel material, especially in the low temperature tank area, spherical tank area, stress corrosion serious area with good corrosion resistance steel, the effect is better.
