Stainless Steel (Stainless Steel) is the abbreviation of stainless acid-resistant steel, resistant to air, steam, water and other weak corrosive media or stainless steel called stainless steel; and will be resistant to chemically corrosive media (acid, alkali, salt and other chemical leaching) corrosion of steel called acid-resistant steel. Due to the differences in the chemical composition of the two and their corrosion resistance is different, ordinary stainless steel is generally not resistant to chemical media corrosion, while acid-resistant steel is generally stainless.
