Stainless steel seamless steel pipe is a long strip of steel with a hollow section and no joints on the periphery. It is a steel pipe resistant to corrosion by weak corrosive media such as air, steam, water and chemical corrosive media such as acid, alkali and salt. Also known as stainless acid-resistant steel pipe.

 

The corrosion resistance of stainless steel seamless pipes depends on the alloying elements contained in the steel. Chromium is the basic element for the corrosion resistance of stainless steel. When the chromium content in the steel reaches about 12%, the chromium interacts with the oxygen in the corrosive medium to form a very thin oxide film (self-passivation film) on the surface of the steel. , Can prevent further corrosion of the steel matrix. In addition to chromium, the commonly used alloying elements of stainless steel seamless pipes include nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., to meet the requirements of various uses for the structure and performance of stainless steel.
