What are the stainless steel

Stainless Steel is defined according to GB/T20878-2007 as the main characteristic of stainlessness and erosion resistance, and the chromium content is at least 10.5%, and the maximum carbon content does not exceed 1.2%.

Stainless Steel (Stainless Steel) is the abbreviation of stainless acid -resistant steel. Weak corrosive media such as air, steam, water or stainless steel is called stainless steel; Eclipse) Corrosive steel types are called acid -resistant steel.

Due to the differences in chemical composition, their corrosion resistance is different, and ordinary stainless steel is generally not resistant to chemical media corrosion, while acid -resistant steel is generally stainless. The term “stainless steel” is not just a kind of stainless steel, but it means more than 100 kinds of industrial stainless steel. Each stainless steel developed has good performance in its specific application field. The key to success is first to clarify the purpose, and then determine the correct steel species. There are usually only six steel species related to the application of architectural structure applications. They all contain 17 to 22%chromium, and better steel species also contain nickel. Add molybdenum can further improve the corrosion of the atmosphere, especially the corrosion resistance to the atmosphere of chloride.
