ASTM 304 Tube Cold-Drawn Stainless Steel Pipe Length 5m No.1 No.2 Surface
Description:
304 stainless steel pipe full name SUS304 stainless steel pipe
SUS304 stainless steel pipe belongs to the U.S. grade material of stainless steel pipe, the domestic grade equivalent to 0Cr19Ni9 stainless steel pipe, usually replaced by 0Cr18Ni9.
The mechanism of stainless steel rust prevention is the formation of dense oxide film of alloying elements to isolate oxygen contact and prevent continued oxidation. So stainless steel is not "stainless".
304 material rust phenomenon, there may be the following reasons.
The presence of chloride ions in the environment.
Chlorine ions are widely available, such as salt, sweat, seawater, sea air, soil, etc.. Stainless steel in the presence of chloride ions in the environment, corrosion is very fast, even more than ordinary low carbon steel.
So there are requirements for the use environment of stainless steel, and it needs to be wiped frequently to remove dust and keep clean and dry.
