What is Stainless Steel?

The distinguishing feature of stainless steels is its high corrosion resistance. Corrosion is an electrochemical process in which metals react with the environment. Stainless steel is not one of the noble metals that can remain inert (does not react with the environment, does not corrode) in most environments, such as gold, platinum, rhodium.

The element that provides high corrosion resistance in stainless steels is the formation of a dense, ductile, thin and transparent chromium-oxide layer on the surface when the material contacts with air. This amorphous layer, which is very thin, provides the required passivity and protection of the internal and external structure against chemical reactions and forms corrosion resistance. Even if the material is processed or the layer is worn out due to the environment where it works, the layer has the ability of repairing itself and regaining its former feature. This amorphous layer, which is also formed in materials such as Titanium (Ti) and Aluminum (Al), greatly increases the value of stainless steel.
