Characteristics of stainless steel seamless steel tube/pipe
- Mar 30, 2018 -

1, the thicker the thickness of the product is, the more economical and practical it is. The thinner the wall thickness, the greater the processing cost will be.


2, the process of the product determines its limited performance, the general seamless steel pipe is of low precision, the wall thickness is not uniform, the inside and outside surface of the tube is low, the cost of the ruler is high, and the internal and external table, the black point and the black point are not easy to remove.


3, its detection and reshaping must be processed off-line. Therefore, it manifests its superiority in terms of high pressure, high strength and mechanical structure.


Stainless steel seamless pipe is a steel pipe corroded by chemical etching medium, such as acid, alkali and salt, which is resistant to air, steam and water. Also known as rust resistant steel pipe.


The corrosion resistance of stainless steel seamless pipe depends on the alloy elements contained in the steel. Chromium is the basic element for corrosion resistance of stainless steel. When chromium content in steel reaches about 12%, chromium and oxygen in corrosion medium form a thin layer of oxide film on the surface of steel (self passivation film), which can prevent the further corrosion of the steel matrix. In addition to chromium, the alloy elements commonly used in stainless steel seamless tubes are nickel, molybdenum, titanium, niobium, copper, nitrogen, etc. to meet the requirements of various uses on the microstructure and properties of stainless steel.


Stainless steel seamless pipe is a kind of hollow circular steel, widely used in oil, chemical, medical, food, light industry, mechanical instruments and other industrial pipeline and mechanical structural components. In addition, when bending and torsional strength are the same, the weight is lighter, so it is also widely used in manufacturing mechanical parts and engineering structures. They are also used to produce various conventional weapons, barrels, shells and so on.
