Features of Super Austenitic Stainless Steel Seamless Pipe and Tube

Huzhou Nanxun Yintuo Special Material Technology Co., Ltd. mainly provides the development and production of Stainless Steel Seamless Pipe. These include Super Austenitic Stainless Steel Seamless Pipe and Tube, if you want to know more, please continue reading.

Stainless steel pipe is a hollow and longitude steel, and the cross section of economical steel is round. Stainless steel pipes have been widely used in petroleum, chemical, medical, food, light industry, equipment and devices, and structural parts. In addition, when the torsion and torsion resistance are equal, stainless steel is lighter, so it is used for equipment parts and engineering structures. It is also used to produce various conventional weapons, barrels, shells, etc. This kind of pipe is divided into: stainless steel seamless pipe and stainless steel welded pipe. According to the manufacturing process, it can be divided into the following basic types: hot rolled, extruded, cold round, hexagonal, equilateral triangle, octagonal and other special-shaped stainless steel pipes

The super austenitic stainless steel alloy is characterized by high nickel, molybdenum content and high nitrogen content. The most common alloys are 904L, AL-6XN, 254 SMO, 25-6MO and 1925 hMO. Super austenitic metals are designed to resist crevice corrosion, pitting, chloride-induced corrosion and stress corrosion cracking. It can also withstand alkaline and salt solutions, prevent the product from being contaminated by metals, and prevent rapid degradation of the fluid transfer system.

A manufacturing method of a super-austenitic stainless steel seamless pipe belongs to the technical field of austenitic stainless steel preparation. The inventor has studied the smelting, casting, electroslag remelting, homogeneous annealing, tube blank forging and heat treatment of seamless tubes, cold working and heat treatment technologies of super austenitic stainless steel, and has allocated cold/hot working deformation technologies and different The size of UNS N08904 and UNS S31254 super austenitic stainless steel seamless pipe finished product setting equipment parameters solves the problem of seamless pipe cracking in the cold and hot rolling deformation zone. The transformation law of super austenitic stainless steel is studied to solve the problem of precipitation of super austenitic stainless steel during metal heat treatment.


We are enterprising with a firm attitude, but at the same time, we are also watching the stars and ambitious ambitions. We are Seamless Pipe Manufacturers, if you are interested and want to buy stainless steel seamless pipes, please contact us!
