Stainless steel refers to steel that is resistant to weak corrosive media such as air, steam, water, and chemical corrosive media such as acid, alkali, and salt, also known as stainless and acid resistant steel. In practical applications, steel that is resistant to weak corrosive media corrosion is often referred to as stainless steel, while steel that is resistant to chemical media corrosion is referred to as acid resistant steel. Due to the differences in chemical composition between the two, the former may not necessarily be resistant to chemical medium corrosion, while the latter generally has rust resistance. The corrosion resistance of stainless steel depends on the alloying elements contained in the steel.
