Stainless steel is the abbreviation of stainless steel, which is resistant to corrosion medium such as air, steam, water or stainless steel.Steel that is resistant to chemical corrosion (acid, alkali, salt, etc.) is called acid-resistant steel.
Due to their differences 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 non-rust.The term "stainless steel" does not simply refer to one kind of stainless steel, but refers to more than 100 kinds of industrial stainless steel.The key to success is first to identify the purpose and then to determine the correct type of steel.There are usually only six types of steel related to the application of building construction.They all contain 17 to 22 percent chromium and good steel also contains nickel.The addition of molybdenum can further improve atmospheric corrosion, especially the corrosion resistance of chloride atmosphere.
Stainless steel refers to the steel that is resistant to corrosion by weak corrosive medium such as air, steam and water and chemical corrosive medium such as acid, alkali and salt.In practical application, steel that is resistant to corrosion is often called stainless steel, while steel that is resistant to chemical corrosion is called acid-resistant steel.Due to their differences in chemical composition, the former is not necessarily resistant to chemical medium corrosion, while the latter is generally non-rust.Corrosion resistance of stainless steel depends on the alloy elements contained in the steel.
Good corrosion resistance and high hardness.Materials common steel, nickel and other categories of metals
