What is stainless steel?
Stainless Steel (Stainless Steel) is the abbreviation of stainless acid-resistant steel, resistant to air, steam, water and other weak corrosive media or stainless steel; The steel that is resistant to chemical corrosion media (acid, alkali, salt and other chemical etching) is called acid-resistant steel.
Due to the difference in the chemical composition of the two, their corrosion resistance is different, ordinary stainless steel is generally not resistant to chemical medium corrosion, and acid-resistant steel is generally stainless. The term "stainless steel" does not simply refer to one kind of stainless steel, but means more than one hundred kinds of industrial stainless steel, each 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 correct steel grade. There are usually only six types of steel related to the application field of building construction. They all contain 17-22% chromium, and the better grades also contain nickel. The addition of molybdenum can further improve the corrosion of the atmosphere, especially the corrosion resistance of the atmosphere containing chloride.
Stainless steel refers to the steel that is resistant to weak corrosive media such as air, steam, water and chemical etching media such as acid, alkali, salt, also known as stainless acid-resistant steel. In practical applications, the steel that is resistant to the corrosion of weak corrosive media is often called stainless steel, and the steel that is resistant to the corrosion of chemical media is called acid-resistant steel. Due to the difference in the chemical composition of 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 alloying elements contained in the steel.
