Stainless steel is the abbreviation of stainless steel, air, steam, water and other weak corrosion medium or stainless steel is called stainless steel;  And the corrosion resistance of chemical corrosion medium ( acid, alkali, salt and other chemical corrosion ) steel is called acid resistant steel.

Due to the difference in chemical composition of the two, their corrosion resistance is different. ordinary stainless steel is generally not resistant to chemical medium corrosion, while acid resistant steel is generally stainless steel.  The term \” stainless steel\” not only refers to a kind of stainless steel, but also means more than 100 kinds of industrial stainless steel, each developed stainless steel has good performance in its specific application field.  The key to success is to figure out what to use first, and then determine the right steel.  There are usually only six types of steel related to the field of architectural applications.  They all contain 17 to 22 percent chromium, and better steel also contains nickel.  Adding molybdenum can further improve atmospheric corrosion, especially chloride-containing atmosphere.

Stainless steel refers to steel resistant to air, steam, water and other weak corrosion medium and acid, alkali, salt and other chemical corrosion medium corrosion, also known as stainless acid resistant steel.  In practice, steel resistant to weak corrosion medium is often called stainless steel, while steel resistant to chemical medium is called acid resistant steel.  Due to the difference in chemical composition between the two, the former is not necessarily resistant to chemical medium corrosion, while the latter is generally stainless.  The corrosion resistance of stainless steel depends on the alloy elements contained in the steel.
