They are alloyed steels containing at least 11% Cr (Chromium) with a chemical structure of at least 11% and their high corrosion resistance is the most important feature. Corrosion is an electrochemical reaction of metals reacting with the environment. Ensure high protection in stainless steels; They are dense, very thin and transparent chromium-oxide layers formed from material materials when in contact with air. Even if the material is processed while being used or the layer it contains is not eroded, it can regain its former feature by repairing itself. Steel structure components, which are the most common usage area.
