304 causes of rust phenomenon in steel

- Oct 28, 2018-

Chloride ions are widely present, such as salt, sweat, sea water, sea breeze, soil and so on.

Stainless steel in the presence of chloride ions in the environment, corrosion is fast, even more than ordinary low carbon steel, chloride ions and alloy elements in FE formation complexes, the FE positive potential is reduced, and then by the oxidizer to remove electrons and be oxidized [1].

Therefore, the use of stainless steel environment requirements, and need to wipe frequently, remove dust, keep clean and dry. 316 and 317 stainless steel is a type of molybdenum-containing stainless steel. 317 The molybdenum content in stainless steel is slightly higher than 316 stainless steel. Because of the molybdenum in 316 stainless steel, the total performance of the steel is better than 310 and 304 stainless steel, under high temperature conditions, when the concentration of sulfuric acid is less than 15% and higher than 85%, 316 stainless steel has a wide range of applications. 316 stainless steel also has good resistance to chloride erosion, so it is commonly used in the marine environment.
