metallographic structure:The organization characteristics of austenite size

In the air or chemical corrosion resistant to corrosion medium of a kind of high alloy steel.The surface of the stainless steel is a beautiful and good corrosion resistance.Don\'t have to color after plating surface treatment, etc.Inherent in the stainless steel surface properties.A kind of use in a variety of steel.Often referred to as stainless steel.On behalf of the performance of 13 chrome steel, 18-8 chrome-nickel steel high alloy steel

From the perspective of metallography analysis,Because the stainless steel containing chromium and make the surface form of very thin chromium film.This film is isolated from intrusion in the steel corrosion o
