Product Introduction
stainless steel (Stainless Steel) according to GB/T20878-2007 is defined as stainless steel, corrosion resistance as the main characteristics, and chromium content of at least 10.5%, carbon content of not more than 1.2% of the maximum steel.
stainless steel is the abbreviation of stainless acid-resistant steel, resistant to air, steam, water and other weak corrosive medium or stainless steel is called stainless steel; and the resistance to chemical corrosion medium (acid, alkali, salt and other chemical etching) corrosion of steel is called acid-resistant steel.
Due to the difference in chemical composition between the two, their corrosion resistance is different. Ordinary stainless steel is generally not resistant to chemical medium corrosion, while acid-resistant steel generally has stainless steel. The term "stainless steel" does not simply refer to a kind of stainless steel, but refers to more than 100 kinds of industrial stainless steel, and each kind of stainless steel developed has good performance in its specific application field. The key to success is to first understand the use, and then determine the correct steel. There are usually only six types of steel related to the application of building construction. They all contain 17 to 22% chromium, and the better steel also contains nickel. The addition of molybdenum may further improve atmospheric corrosion, particularly corrosion resistance to chloride-containing atmospheres.
Generally speaking, the hardness of stainless steel is higher than that of aluminum alloy, and the cost of stainless steel is higher than that of aluminum alloy.
