What does 304 stainless steel mean?
Jul 25, 2022
Generally speaking, stainless steel is not easy to rust steel, in fact, a part of stainless steel, both rust, and acid resistance (corrosion resistance). The rust resistance and corrosion resistance of stainless steel are due to the formation of chromium-rich oxide film (passivation film) on its surface. This rust resistance and corrosion resistance are relative. The experimental results show that the corrosion resistance of steel increases with the increase of chromium content in weak media such as air, water and oxidizing media such as nitric acid. When the chromium content reaches a certain percentage, the corrosion resistance of steel changes from easy to rust, from corrosion resistance to corrosion resistance.
