what is stainless steel?
In the science and technology of metals (known as Metallugy), stainless steel is a a carbon and iron mixture with a minimum of 10.5% chromium content by mass. Stainless steel is not 100% stain proof in low oxygen, high salinity or poor air circulation environments but does not easily corrode, rust or stain when coming into contact with water than ordinary steel does. For the alloy to endure a specific environment, there are different grades and surface finishes to suit the application. It is used when both the corrossion resistance and properties of steel are required.
stainless steel grades
A number of standards organisations have developed steel grades to classify various steels by their composition and physical properties.

Stainless steel's surface consists of an extremely thin but stable Chromium rich oxide film, on which it relies on for optimum corrosion resistance.
