Common stainless steel is generally not resistant to chemical medium corrosion, while acid-resistant steel generally has corrosion resistance. The term "stainless steel" does not simply refer to a single type of stainless steel but indicates over a hundred industrial stainless steels. Each type of stainless steel developed performs well in its specific application field. The key to success is first to determine the purpose, and then to identify the correct steel type. The steel types typically used in construction and structural applications are usually only six. They all contain 17-22% chromium, with better grades also containing nickel. Adding molybdenum can further...EnhanceAtmospheric corrosiveness, particularly resistance to chloride-containing atmosphere corrosion.
Stainless steel is a shorthand for acid-resistant steel. It refers to steel grades that are resistant to weak corrosive media such as air, steam, and water, or steel grades with inherent corrosion resistance. In contrast, steel that resists corrosion from chemical agents (acids, alkalis, salts, etc.) is called acid-resistant steel. Due to their differences in chemical composition, the corrosion resistance of the two types varies. General stainless steel is typically not resistant to chemical media corrosion, while acid-resistant steel generally possesses corrosion resistance.
