In general, our pet cage uses 304 stainless steel. Stainless steel pet cages will also rust under certain conditions. Stainless steel has the ability to resist atmospheric oxidation - that is, stainless, but also has the ability to resist corrosion in media containing acid, alkali, salt - that is, corrosion resistance. However, the corrosion resistance of the steel varies with the chemical composition of the steel itself, the interaction state, the conditions of use, and the type of environmental media.
For example, the following conditions may cause the 304 stainless steel pet cage to rust:

1. The surface of stainless steel pet cages contains deposits of dust or other dissimilar metal particles containing other metal elements. In moist air, the condensate between the attachment and stainless steel connects the two to form a micro battery, causing electricity. Chemical reaction, the protective film is destroyed, known as electrochemical corrosion. To avoid this, as long as the stainless steel surface is kept dry and clean, stainless steel pet cages will not be rusted.
2, if the stainless steel pet cage surface adhesion organic matter juice (such as vegetables, noodles, soup, etc.), in the case of water oxygen, constitute organic acids, long time the organic acid on the metal surface corrosion.
3, stainless steel pet cage surface contains acid, alkali, salt substances (such as the decoration of the wall of alkaline water, lime water spray), causing local corrosion.

4. In contaminated air (such as an atmosphere containing a large amount of sulfides, carbon oxides, and nitrogen oxides), condensed water is formed and sulfuric acid, nitric acid, and acetic acid liquids are formed, causing chemical corrosion. The above conditions can cause the corrosion of the stainless steel pet cage surface protection film to cause corrosion.
Therefore, in order to ensure that the stainless steel pet cage is permanently bright and not rusted, we recommend:
1. The stainless steel pet cage must be cleaned and scrubbed frequently to keep the stainless steel pet cage clean and dry, and it can ensure that the stainless steel pet cage is always bright.

2, the use of 316 stainless steel in the waterfront area, 316 material can resist seawater corrosion.
3. Some stainless steel pet cages on the market do not use 304 or higher materials. The so-called 202, 201 stainless steel is very easy to rust. Please do not try to use the stainless steel pet cage when you buy. Then the question is, why is it easy to rust also called stainless steel? 201, 202 stainless steel in the clean air is rust-proof, such as home decoration ceiling edging, clean and rust-proof, not for the dog to use Because the dog is erosive.
