Stainless steel (Stainless Steel) is referred to as the stainless steel, the resistance of air, steam, water and other weak corrosive medium or with stainless steel known as stainless steel; while the resistance to chemical corrosion (acid, alkali and salt chemical etching) corrosion of steel called acid resistant steel.
Because of the difference in the chemical composition and corrosion resistance of their different, generally not ordinary stainless steel corrosion and acid resistant steel, generally are not rust. "Stainless steel" is not just simply refers to a kind of stainless steel, but that the one hundred kinds of industrial stainless steel, each kind of stainless steel developed has good performance in its specific application areas. The key to success is to understand the use of the first, and then determine the right material. The relevant material and construction applications usually only six. They all contain 17 ~ 22% chromium, good steel containing nickel. Adding molybdenum can further improve the atmospheric corrosion, especially the corrosion resistance of chloride containing atmosphere.
