WHAT IS STAINLESS STEEL?

The distinguishing feature of stainless steels is high corrosion resistance. Corrosion is an electro-chemical process in which metals react with the environment. Stainless steel; It is not a noble metal such as gold, platinum and rhodium, which can remain inert in most environments (does not react with the environment and does not corrode).

The element that provides high corrosion resistance in stainless steels; It is the formation of a dense, ductile, very thin and transparent chromium-oxide layer on the surface of the material when it comes into contact with air, which adheres strongly to the surface. This very thin amorphous layer provides the necessary passivity, protecting the internal and external structure against chemical reactions and ensuring stainless steel. Even if the material is processed while being used or the layer on top of it is worn out due to the place where it is used, this layer has the feature of repairing itself and regaining its former properties. This amorphous layer, which also occurs in materials such as Titanium (Ti) and Aluminum (Al), increases the value of stainless steel considerably.

This at least 10.5% Chromium (Cr) rate added to stainless steel ensures that the superficial and internal structure of the steel resists external factors and prevents it from rusting. Low alloy types of stainless steel are susceptible to atmospheric conditions and natural water; Highly alloyed types are resistant even to environments containing acid, alkaline solutions and chloride.
