Stainless steel seamless pipe is a steel pipe that is resistant to weak corrosive media such as air, steam, water, and chemically 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 stainless steel to obtain corrosion resistance. When the chromium content in the steel reaches about 12%, the chromium interacts with the oxygen in the corrosive medium to form a thin oxide film on the surface of the steel, can prevent further corrosion of the steel matrix. In addition to chromium, commonly used alloying elements for stainless steel seamless pipes include nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., to meet the requirements for the structure and performance of stainless steel for various purposes. Stainless steel seamless pipes are widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural components.
