How do stainless steel fasteners do not rust four points can worry

Time:2022-11-03

　　Stainless steel is called stainless steel, but by no means will not rust, we should know how to avoid product rust when using stainless steel fasteners. In the process of use, rust is a common phenomenon, but also let us worry about things, this will not only affect the beauty, but also affect the use of stainless steel screw performance.

　　Therefore, we must pay attention to the main points of use in the process of using stainless steel screws. The following are four points summarized by Xiaobian for your reference:

　　1, in the polluted air (such as containing a large number of sulfide, carbon oxide, nitrogen oxide atmosphere), in the case of condensation water, the formation of sulfuric acid, nitric acid, acetic acid liquid point, causing chemical corrosion.

　　2, stainless steel screw surface adhesion organic juice (such as melons and vegetables, noodle soup, sputum, etc.), in the case of water oxygen, organic acid, organic acid corrosion of metal surface for a long time.

　　3, dust or alien metal particles of the attachment, in the humid air, the attachment and stainless steel screw condensate, the two will be connected into a micro battery, triggered an electrochemical reaction, protective film is damaged, called electrochemical corrosion.

　　4, stainless steel surface adhesion containing acid, alkali, salt substances (such as the decoration of the wall of alkali water, lime water splash), cause local erosion.
