Complete knowledge of stainless steel

For PVD, the corrosion resistance of the coating is very important influence on the corrosion resistance of the substrate, different substrate, PVD coating the same between the corrosion test of stainless steel material great effect, see the following knowledge, you will find many kinds of stainless steel, according to the different conditions of corrosion resistance is not the same, resulting in corrosion resistance of the coating surface is not the same.

Definition of stainless steel
A high alloy steel corrosion resistance in the air or chemical corrosion, stainless steel is a beautiful surface and good corrosion resistance, without plating surface treatment, its inherent surface properties of stainless steel, used in many aspects of steel, often called stainless steel.

Represents the properties of 13 steel, chromium nickel steel and high alloy steel 18-. E-BON the stainless steel specialist, China Stainless steel Barware factory. 

From metallographical analysis, stainless steel contains chromium to form a thin chromium film on the surface, which separates the oxygen from the steel and acts as an anticorrosive agent. In order to maintain the corrosion resistance inherent to the stainless steel, the steel must contain more than 12% chromium.
