Causes and treatment of stainless steel rust

Reasons for stainless steel rust:

The surface of the stainless steel contains dust or other metal particles attached to other metal elements. In humid air, the condensed water between the attached material and the stainless steel connects the two into a micro battery, triggering an electrochemical reaction. The protective film is destroyed, which is called electrochemical corrosion.

The surface of the stainless steel adheres to the organic juice (such as melon, noodle soup, glutinous rice, etc.), and in the case of water and oxygen, it constitutes an organic acid, and the organic acid corrodes the metal surface for a long time.

The surface of the stainless steel adheres to acid, alkali and salt substances (such as alkali water and stone water splashing on the wall), causing local corrosion.

In polluted air (such as the atmosphere containing a large amount of sulfide, carbon oxide, nitrogen oxide), in the case of condensed water, sulfuric acid, nitric acid, acetic acid liquid point is formed, causing chemical corrosion.

Treatment of stainless steel rust:

The surface of the decorative stainless steel must be cleaned and scrubbed frequently to remove the deposits and eliminate external factors that cause modification.

316 stainless steel is used in the coastal area, and 316 is resistant to seawater corrosion.

Some stainless steel tube chemical components in the market can not meet the corresponding national standards, and can not meet the 304 material requirements. Therefore, it will also cause rust, which requires the user to carefully select the products of reputable manufacturers.
