Description:
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 18-8.
From the perspective of metallography analysis, because stainless steel containing chromium and chromium on the surface to form a thin film, the film off the invasion and oxygen in steel corrosion effect.
In order to keep the corrosion resistance of stainless steel, the steel must contain more than 12% of the chromium.
