square tube stainless steel 8mm rectangular tubing metal pipe

Stainless steel square tube use:

The stainless steel square tube is a hollow, long strip of steel. It is called a square tube because of its square cross-section. A large number of pipelines are used to transport fluids, such as oil, natural gas, water, gas, steam, etc. In addition, when the bending and torsion strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures.

Features of stainless steel rectangular tube

Whether the stainless steel pipe is corroded is related to the chromium content in the steel. When the chromium content in the steel reaches 12%, in the atmosphere, a layer of passivated and dense chromium-rich oxide is formed on the surface of the stainless steel pipe to protect the surface. Further oxidation. This oxide layer is extremely thin, and the natural luster of the steel surface can be seen through it, giving the stainless steel a unique surface. If the chromium film is damaged, the chromium in the steel and the oxygen in the atmosphere will regenerate a passivation film to continue to play a protective role. In some special environments, stainless steel will also fail due to some local corrosion. However, unlike carbon steel, stainless steel will not fail due to uniform corrosion, so the corrosion allowance is meaningless for stainless steel pipes.
