Common stainless steel is generally not resistant to chemical medium corrosion, whereas acid-resistant steel generally possesses corrosion resistance. The term "stainless steel" does not simply refer to a single type of stainless steel but denotes 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 grade. In the field of architectural and structural applications, there are typically only six types of steel. 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 stainless steel. It refers to steel grades that are resistant to weak corrosive media such as air, steam, and water, or those with inherent corrosion resistance. On the other hand, steel that resists corrosion from chemical agents (acids, alkalis, salts, etc.) is known as acid-resistant steel. Due to their differences in chemical composition, the corrosion resistance varies; ordinary stainless steel is generally not resistant to chemical corrosion, while acid-resistant steel generally possesses corrosion resistance.
