Causes Of 304 Stainless Steel Rust

Oras: 2022-04-28 Mga Hits: 4

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

Therefore, there are requirements 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. Molybdenum content in 317 stainless steel is slightly higher than 316 stainless steel. Because 316 stainless steel contains molybdenum, its overall performance is better than 310 and 304 stainless steel. Under high temperature conditions, when the sulfuric acid concentration is lower than 15% and higher than 85%, 316 stainless steel has a wide range of uses. 316 stainless steel also has good resistance to chloride attack, so it is usually used in marine environments.
