Stainless steel ko, also known as inox (from the French original: inoxydable) is one the alloy steel containing Cr property (with a minimum chromium content of 10.5% by weight). if as a conventional steel when exposed property oxidizing agents (such as air, moisture ...) will form rust and corrosion on the inside layer of material, then in stainless steel coil , the content Cr high enough, on the surface it will form one layer of chromium oxide film that brought negative effects generated era prevented rust and corrosion on the inside layer of material surface makes it always feels shiny. Thanks to the superior properties, current, stainless steel does not apply in the industrial diversity, health, life ... besides, because the name "stainless", this also makes the material or be abused for many different purposes, particularly with those applied in life. But the reality, resistant to corrosion of the steel depends according to its alloy components and the environment of use, universal in the case, it is also susceptible to corrosion property than normal steel (especially in saline chlorination, eg NaCl salt ...)
