The characteristics of stainless steel

Stainless Steel (Stainless Steel) refers to the resistance to weak corrosive medium such as air, steam, water and acid, alkali, salt and other chemical etching medium corrosion of the Steel, also called acid-proof Stainless Steel. In practical application, often called the weak corrosive medium corrosion resistant steel stainless steel, and called the resistance to chemical corrosion medium steel acid-resistant steel. Due to the chemical composition on the difference between the two, the former is not resistant to chemical corrosion medium, while the latter are generally not rust. The corrosion resistance of stainless steel depends on the alloy element content in the steel. Stainless steel alloy elements and basic nickel, molybdenum, titanium, niobium, copper, nitrogen, etc, in order to meet the requirements of various applications on the microstructure and mechanical properties of stainless steel. Stainless steel is easy to chlorine ion corrosion, because of the chromium, nickel, chlorine isotopic elements.
