Stainless steel does not rust easily because it has a protective layer of chromium oxide, which prevents the metal from reacting with oxygen in the air.
Stainless steel is a type of steel that does not corrode. It is resistant to corrosion because it has a thin layer of chromium oxide, which covers the surface and prevents it from rusting. This is different from other types of metal like iron or copper, which can be corroded by water and oxygen in the air. The chromium oxide layer on stainless steel will eventually wear away when exposed to corrosive substances such as salt water or acid rain.
Q: What is stainless steel 18-8 (sUS304)
SUS304 is a stainless steel with a minimum 18% chromium and 8% nickel content. The 304 refers to the type of stainless steel, which is the second most common type of stainless steel. The SUS stands for “stainless steel” and the 304 refers to the fact that it has a minimum 18% chromium content.
SUS304 is one of the most common material for stainless steel insulated water bottles and it is most common corrosion resistant steels available on the market. It can be used in any environment where you would use another form of stainless steel, such as food processing or water treatment plants. It has excellent resistance to corrosion when exposed to salt water, chlorides, sulfuric acid and nitric acid.
