317L 309S Round Stainless Steel Pipe 8mm 304 2D Cold Rolling

Round Stainless Steel Pipe 304 Material With Quality Certificate

According to the different manufacturing processes can be: hot rolling, extrusion, cold drawing and cold rolling these basic types, according to the cross-sectional shape can be divided into round pipe and special-shaped pipe, widely used is circular steel pipe, but there are also some square, rectangular, semi-circular, hexagonal, equilateral triangle, octagonal and other special-shaped stainless steel pipe.
For the steel pipe that bears the fluid pressure, the hydraulic test should be carried out to test its pressure resistance and quality, and no leakage, wetting or expansion will be qualified under the specified pressure, and some steel pipes should also be crimped test, flaring test and flattening test according to the standard or demand requirements.
Seamless stainless steel round pipe, also known as stainless steel seamless pipe, is made of steel ingot or solid pipe blank through perforation to make a capillary, and then by hot rolling, cold rolling or cold dialing. The specifications of seamless steel pipes are expressed in millimeters of outer diameter * wall thickness.
304 stainless steel round pipe full name SUS304 stainless steel pipe, SUS304 stainless steel round pipe belongs to the United States grade of stainless steel pipe, the domestic grade is equivalent to 0Cr19Ni9 stainless steel pipe, usually replaced by 0Cr18Ni9. The mechanism of stainless steel rust prevention is that alloying elements form a dense oxide film, which isolates oxygen contact and prevents further oxidation.
