Chloride ions exist widely, such as salt, sweat, seawater, sea breeze, soil, etc.
In the presence of chloride ions, stainless steel corrodes faster, even than ordinary low carbon steel, chloride ions and FE in alloying elements form a complex, which reduces the positive potential of FE, and then is removed by oxidants and oxidized.
Therefore, the use environment of stainless steel is required, and it needs to be wiped frequently to remove dust and keep it clean and dry. 316 and 317 stainless steel is a molybdenum-containing stainless steel. The molybdenum content in 317 stainless steel is slightly higher than that in 316 stainless steel. Due to the molybdenum in 316 stainless steel, the comprehensive performance of the steel is better than that of 310 and 304 stainless steel. Under high temperature conditions, when the sulfuric acid concentration 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 corrosion, so it is commonly used in marine environments.
