     What is stainless steel?
   Stainless steel is the abbreviation of stainless and acid resistant steel, which is called stainless steel for its resistance to weak corrosive media such as air, steam, water or stainless steel, and acid resistant steel for its resistance to chemical corrosive media such as acid, alkali, salt, etc.           
   Due to the difference in chemical composition, their corrosion resistance is different. Ordinary stainless steel is generally not resistant to chemical medium corrosion, while acid resistant steel is generally stainless. The term "stainless steel" not only refers to one kind of stainless steel, but also represents more than one hundred kinds of industrial stainless steel. Each kind of stainless steel developed has good performance in its specific application field. The key to success is first to understand the purpose, and then to determine the right steel grade. There are usually only six kinds of steel related to the application field of building construction. They all contain 17-22% chromium, and the better steel also contains nickel. The addition of molybdenum can further improve atmospheric corrosivity, especially the resistance to chloride atmosphere.           
   Stainless steel refers to the steel resistant to weak corrosive media such as air, steam, water and chemical corrosive media such as acid, alkali and salt, also known as stainless acid resistant steel. In practical application, the steel resistant to weak corrosion medium is often called stainless steel, while the steel resistant to chemical medium is called acid resistant steel. Due to the difference in chemical composition, the former is not necessarily resistant to chemical medium corrosion, while the latter is generally rust free. The corrosion resistance of stainless steel depends on the alloy elements contained in the steel.
