Stainless steel rectangular tube is a type of hollow steel strip that is widely used in pipelines for conveying fluids such as petroleum, natural gas, water, gas, steam, etc. In addition, it is lighter in weight when bending and torsional strength are the same, so it is also widely used in the manufacturing of mechanical parts and engineering structures.

Metals can react with oxygen in the atmosphere to form an oxide film on the surface. The iron oxide formed on ordinary carbon steel will continue to oxidize, causing corrosion to expand and ultimately forming pores. This can be achieved by electroplating with paint or oxidation resistant metal to protect the surface of carbon steel, but this protective layer is only a thin film. If the protective layer is damaged, the steel below will begin to rust again. Whether stainless steel pipes are corroded is related to the chromium content in the steel. When the chromium content in the steel reaches 12%, a layer of passive and dense chromium rich oxide is formed on the surface of stainless steel pipes in the atmosphere to protect the surface and prevent further oxidation. This type of oxide layer is extremely thin, through which the natural luster of the steel surface can be seen, giving 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, continuing to play a protective role. In some special environments, stainless steel may also experience localized corrosion and failure, but unlike carbon steel, stainless steel does not exhibit uniform corrosion and failureIn industry, stainless steel square pipes are mainly used to manufacture some pipelines. Of course, it is more widely used in the construction industry, such as staircase handrails, window guardrails, railings, road partitions, etc. Currently, many products use stainless steel pipes, such as bicycles, medical devices, cars, etc
