product description

Stainless steel plate is generally a general term for stainless steel plate and acid-resistant steel plate.

Introduced at the beginning of this century, the development of stainless steel plate has laid an important material and technical foundation for the development of modern industry and scientific and technological progress.

There are many types of stainless steel plates with different properties. It has gradually formed several categories in the development process.

Corrosive conditions

1. On the surface of stainless steel, there are deposits of dust or heterogeneous metal particles containing other metal elements. In humid air, the condensed water between the deposits and the stainless steel connects the two into a micro-battery, which triggers an electrochemical reaction. , the protective film is damaged, called electrochemical corrosion.

2. Organic juices (such as vegetables, noodle soup, sputum, etc.) adhere to the surface of stainless steel. In the presence of water and oxygen, organic acids are formed, and organic acids will corrode the metal surface for a long time.

3. The surface of stainless steel adheres to substances containing acids, alkalis and salts (such as alkali water and lime water splashing from the decoration walls), causing local corrosion.

4. In the polluted air (such as the atmosphere containing a large amount of sulfide, carbon oxide, nitrogen oxide), in the presence of condensed water, the formation of sulfuric acid, nitric acid, acetic acid liquid spots, causing chemical corrosion The above conditions can cause the protective film on the stainless steel surface. Damage causes rust.
