introduction：In popular terms，Stainless steel is steel that does not rust easily，Actually part stainless steel，Both rust proof，Its also acid resistant（Corrosion resistance）。Stainless steels rustlessness and corrosion resistance are due to the chromium-rich oxide film on its surface（Passivation film）The formation of。This rustlessness is relative to corrosion resistance。The test shows that，Steel in atmosphere、In weak medium such as water and oxidizing medium such as nitric acid，The corrosion resistance increases with the increase of chromium water content in the steel，When the chromium content reaches a certain percentage，The corrosion resistance of steel has changed dramatically，From easy to rust to not easy to rust，From non-corrosion resistant to corrosion resistant。There are many ways to classify stainless steel。According to room temperature structure
