Will stainless steel pipe rust?

　　The antirust mechanism of stainless steel pipe is that alloy elements form a dense oxide film to isolate oxygen contact and prevent further oxidation. So stainless steel pipes will rust.

　　There are several possible reasons for the rusting of 304 material:

　　There is chlorine ion in the use environment.

　　Chlorine ions exist widely, such as salt, sweat, sea water, sea breeze, soil, etc. Stainless steel corrodes rapidly in the presence of chloride ions, even surpassing ordinary low-carbon steel.

　　Therefore, there are requirements for the use environment of stainless steel, and it is necessary to wipe it regularly to remove dust and keep it clean and dry.

　　316 and 317 stainless steels (see below for the properties of 317 stainless steels) are molybdenum containing stainless steels. The molybdenum content in 317 stainless steel is slightly higher than that in 316 stainless steel. Because of the molybdenum in the steel, the overall performance of this steel is better than 310 and 304 stainless steel. Under high temperature conditions, when the concentration of sulfuric acid is lower than 15% and higher than 85%, 316 stainless steel has a wide range of uses. 316 stainless steel also has good chloride corrosion resistance, so it is usually used in marine environment.

　　With the development of social economy, the application of stainless steel pipe has also been more and more widely used. It will bring new changes in all fields.

　　Theoretical weight of stainless steel pipe: W=outer diameter - wall thickness x wall thickness x 0.02491.

　　Stainless steel will not cause corrosion, pitting, rust or wear. Stainless steel is also one of the strongest metal materials used in construction. Because stainless steel has good corrosion resistance, it can make structural components permanently maintain the integrity of engineering design.
