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 tubes, usually replaced with 0Cr18Ni9.
The stainless steel rust prevention mechanism is that alloying elements form a solid oxide film, which is in contact with oxygen to prevent further oxidation. So stainless steel is not “rustproof”.
Stainless steel rectangular tube is a hollow long steel strip with rectangular cross section, so it is called rectangular tube. It is used as a scaffolding frame structure, such as oil, natural gas, water, gas, steam, etc. In addition, it is involved in bending forces and torsion. At the same time, it weighs less and therefore is widely used in the manufacture of mechanical components and engineering structures. Also used to produce various conventional weapons, barrels, shells and so on.
