304 stainless steel rectangular tube

SUS304 stainless steel tube is a stainless steel tube of American grade material. The domestic grade is equivalent to 0Cr19Ni9 stainless steel tube, usually replaced by 0Cr18Ni9.

The mechanism of stainless steel rust prevention is that the alloying elements form a dense oxide film, which is in contact with oxygen to prevent further oxidation. So stainless steel is not "stainless".

Stainless steel rectangular tube is a hollow long strip of steel with a rectangular cross section, so it is called a rectangular tube. It is used as a scaffolding frame structure, such as oil, natural gas, water, gas, steam, etc. In addition, it is engaged in bending and torsional strength. At the same time, it is lighter in weight and is therefore widely used in the manufacture of mechanical parts and engineering structures. Also used to produce a variety of conventional weapons, barrels, shells and so on.
