Yes, the stainless steel you know is also know as INOX steel. You might be wondering why is it called so?? The reason being, due to presence of minimum of 10% chromium in stainless steel, a layer of chromium-rich oxide film forms on its surface making the steel inoxydable. INOX is taken from this french word "Inoxydable".
Stainless steel is the name given to a group of corrosion resistant and high temperature steels. When ordinary carbon steel is exposed to rain water, for example, it corrodes forming a brown iron oxide, commonly called rust, on the surface. This is not protective and eventually the entire piece of steel will corrode and be converted to rust. But when enough chromium (more than about 10%) is added to ordinary steel, the oxide on the surface is transformed - it is very thin, virtually invisible and protective in a wide range of corrosive media.
A great read. We work a lot with stainless steel to make u-bolts and pipe supports as well as a range of fasteners.
ReplyDeleteIt is worth mentioning that stainless steel is not "inoxydable" as the name suggest. It can oxidise in the right situation
