Stainless steel seamless pipe is a corrosion resistant medium corrosion medium, such as air, steam, water and other weak corrosion medium, and the corrosion of corrosion medium of acid, alkali and salt. Also known as rust resistant steel pipe.
The corrosion resistance of the stainless steel seamless tube depends on the alloy elements contained in the steel. Chromium is the basic element to obtain corrosion resistance of stainless steel. When the chromium content in steel reaches 12%, chromium will react with oxygen in corrosive medium to form a thin oxide film on the surface of steel, which can prevent further corrosion of steel matrix.
Besides chromium, the alloy elements commonly used in stainless steel seamless pipes include nickel, molybdenum, titanium, niobium, copper and nitrogen to meet the requirements of various uses for the structure and performance of stainless steel.
Stainless steel seamless pipe is a hollow long strip steel, widely used in petroleum, chemical, medical, food, light industry, machinery and meters, and other industrial pipeline and mechanical components. In addition, when the bending and torsion strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures.
It is also used to produce all kinds of conventional weapons, guns, shells and so on.
