Stainless steel screws usually refer to steel screws that have the ability to resist corrosion from air, water, acid, alkali salt or other media.

Stainless steel screws are generally not easy to rust, durable, and can be used in environmental protection equipment, communication equipment and other fields.

In daily life, stainless steel screws are common fasteners. In the process of using stainless steel screws, rust is a common phenomenon and an annoying thing for us.

This will not only affect the aesthetics, but also affect the quality of stainless steel screws. Use performance, so during use.

We must pay attention to the following points:

1.The surface of the stainless steel screw adheres to the organic juice (such as melon, vegetable, noodle soup, sputum, etc.),

which forms organic acid in the presence of water and oxygen, and the organic acid will corrode the metal surface for a long time.

2.The attachment of dust or foreign metal particles. In the humid air, the attachment and the condensed water of the stainless steel screw connect the two to form a micro battery,

triggering an electrochemical reaction and destroying the protective film, which is called electricity Chemical corrosion.

3.In polluted air (such as the atmosphere containing a large amount of sulfide, carbon oxide, and nitrogen oxide),

it will form sulfuric acid and acetic acid liquid spots in contact with condensed water, causing chemical corrosion.

4.The surface of stainless steel is adhered to contain acid, alkali, and salt substances (such as alkaline water and lime water splashing on the decoration wall), causing local corrosion.
