Stainless steel is a special category of different iron base alloys which are formulated of different elements like Iron, Chromium, Nickel. These iron base alloys have good mechanical properties and manufacturing characteristics and are corrosion resistance to sea water and concentrated acids.
Commonly, when carbon steel comes in contact with aqueous solutions they tend to form brown iron oxide called rust, on its surface. Due to the presence of Chromium, which is the most important element that gives these iron based alloys their basic corrosion resistance strength and also resistance to oxidation at higher temperatures.
There are many different grades in this category which have their unique characteristics and properties in different conditions and environments.
