definition of stainless steel
A type of high alloy steel that can resist corrosion in air or chemical corrosive media. Stainless steel has a beautiful surface and good corrosion resistance, without the need for surface treatment such as plating, and utilizes the inherent surface properties of stainless steel. It is commonly used in various types of steel and is called stainless steel. High alloy steels such as 13 chromium steel and 18 chromium nickel steel represent performance.
From a metallographic perspective, stainless steel contains chromium and forms a very thin chromium film on the surface, which separates it from the oxygen invading the steel and plays a corrosion-resistant role.
In order to maintain the inherent corrosion resistance of stainless steel, steel must contain more than 12% chromium.
