Stainless steel round bar is a kind of hollow long round steel, mainly widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial transmission pipeline and mechanical structure parts, etc..
In addition, in the bending, torsional strength of the same, lighter weight, so also widely used in the manufacture of mechanical parts and engineering structures. Such steel tubes can be divided into two categories: stainless steel seamless steel tubes and stainless steel welded steel tubes (seamed tubes).
According to the different manufacturing processes can be: hot-rolled, extruded, cold-drawn and cold-rolled these basic types, according to the shape of the section can be divided into round and shaped tube, widely used is round steel bar, but there are some square, rectangular, semi-circular, hexagonal, equilateral triangle, octagonal and other shaped stainless steel bar.
For steel tubes subjected to fluid pressure are subjected to hydraulic pressure test to test its pressure resistance and quality, under the specified pressure does not occur leakage, wetting or demand side requirements for rolled edge test, flaring test, flattening test.
316 and 317 stainless steel (317 stainless steel properties see later) are molybdenum-containing stainless steel grades. 317 stainless steel has a slightly higher molybdenum content than 316 stainless steel.
304 stainless steel round bar full name SUS304 stainless steel pipe, SUS304 stainless steel round pipe belongs to the United States grade material of stainless steel pipe, the domestic grade equivalent to 0Cr19Ni9 stainless steel pipe, usually with 0Cr18Ni9 instead. The mechanism of stainless steel rust prevention is the formation of dense oxide film of alloying elements to isolate oxygen contact and prevent continued oxidation. So stainless steel is not “stainless”.
Initially，316 stainless steel round bar is a kind of hollow long round steel, mainly widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial transmission pipeline and mechanical structure parts, etc.. In addition, in the bending, torsional strength of the same, lighter weight, so also widely used in the manufacture of mechanical parts and engineering structures.
Apart from that, 316 stainless steel also has good resistance to chloride erosion, so it is usually used in the marine environment. Stainless steel bar with the social and economic development, its application has been more and more widely popular. It will certainly bring a new change in various fields. Theoretical weight of stainless steel pipe: W = (OD – wall thickness) x wall thickness x 0.02491 x length.
