In layman's terms, that is not easy to rust stainless steel, in fact, part of the stainless steel, both of stainless steel, but also acid resistance (corrosion resistance). And corrosion resistance of stainless steel is due to its chromium-rich oxide film on the surface (passivation film) formation. This stainless steel and corrosion resistance is relative. Tests showed that the steel in the atmosphere, water or the like medium and weak nitric acid and other oxidizing medium, the corrosion resistance of the steel with the increase of water content of chromium improves, when the chromium content reaches a certain percentage, the occurrence of corrosion resistance of the steel mutations that rust from easy to rust, never corrosion to corrosion.
