Product Description

2205 38.1*1.5mm Stainless Steel Seamless Pipe Tube ASTM A312 ASME SA312


Duplex 2205  Stainless Steel

 

The main alloying elements of duplex steel are Cr, Ni, Mo and N. Among them, Cr and Mo increase ferrite content, while Ni and N are austenite stable elements. Some steels also contain elements such as Mn, Cu and W. Cr, Ni and Mo can improve the corrosion resistance. In the chloride-containing environment, its pitting and crack corrosion resistance is particularly good.

2205 Seamless pipe is a hollow long round steel, widely used in petroleum, chemical, medical, food, light industry, mechanical instruments, such as industrial pipelines and mechanical structural components. In addition, the bending, torsional strength of the same time, light weight, widely used in the manufacture of mechanical parts and engineering structures. Also used for the production of various conventional weapons, barrels, shells and so on.

 

2205 Seamless pipe thickness thicker, it is more economical and practical, the thinner the wall thickness, its processing costs will be greatly increased; 2205Seamless tube of the process to determine its limitations, the general seamless steel tube accuracy: uneven wall thickness, the tube surface brightness, low, fixed-ruler cost high, and the appearance of Hemp point, black spots are not easy to remove;  Seamless pipe inspection and shaping must be processed off-line. So it shows its superiority in high pressure, high strength and mechanical structure material.
