Characteristics of stainless steel

Stainless steel is the abbreviation of stainless acid-resistant steel, air, steam, water and other weak corrosive media or stainless steel is called stainless steel; and will be resistant to chemical corrosive media (acids, alkalis, salts and other chemical impregnation) corrosion of steel is called acid-resistant steel.

Because of the differences in the chemical composition of the two and their corrosion resistance is different, ordinary stainless steel is generally not resistant to chemical media corrosion, and acid-resistant steel are generally stainless. The term "stainless steel" does not simply refer to one type of stainless steel, but to more than a hundred types of industrial stainless steel, developed for each type of stainless steel has good performance in their specific applications. The key to success is first to find out what the application is and then to identify the correct grade.

There are usually only six steel grades relevant to building construction applications. They all contain 17 to 22 per cent chromium, and the better grades also contain nickel. The addition of molybdenum further improves atmospheric corrosion resistance, especially to chlorinated atmospheres.

In general, stainless steels are harder than aluminium alloys, and the cost of stainless steels is higher than that of aluminium alloys.
