Reasons for the rust of 304 steel

  Chloride ions are widely present, such as salt, sweat, sea water, sea breeze, soil, and so on. In the environment of chloride ion, stainless steel corrodes quickly, even more than ordinary low carbon steel. Chloride ion forms a complex with Fe in the alloying element, which reduces the positive potential of Fe and is then oxidized by the oxidant to remove electrons.

  Therefore, there is a requirement for the use environment of stainless steel, and it is necessary to wipe frequently to remove dust and keep it clean and dry.

  316 and 317 stainless steels are molybdenum-containing stainless steels. The molybdenum content of 317 stainless steel is slightly higher than that of 316 stainless steel. Since 316 stainless steel contains molybdenum, the total performance of this steel is better than that of 310 and 304 stainless steel. When the concentration of sulfuric acid is lower than 15% and higher than 85% under high temperature conditions. , 316 stainless steel has a wide range of uses. 316 stainless steel also has good resistance to chloride attack and is therefore commonly used in marine environments.
