The corrosion resistance of stainless steel depends on chrome, but because chromium is an integral part of one of the steel protection methods are not the same.
Chrome add up to 10.5%, the atmospheric corrosion of steel can be significantly increased, but the higher chromium content, although it can still improve corrosion resistance, but not obvious. The reason is that the alloying of steel with chromium, the type of surface oxides change became similar to the surface oxide formed on pure chromium metal. The tight adhesion of chromium-rich oxide surface protection to prevent further oxidation. This thin oxide layer, through which you can see the natural luster of the steel surface, stainless steel has a unique surface. Moreover, if the damage to the surface, the exposed steel surface and atmospheric response to self-repair, re-formation of this oxide passive film, continue to play a protective role. Therefore, all stainless steel elements have a common characteristic, that the chromium content of 10.5%.

In addition to the chrome outside, the common alloying elements there are nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., in order to meet the requirements of the various uses of the organization and performance of stainless steel.
