304 material rust

The use of chloride ions in the environment

Chloride ions are widespread, such as salt, sweat, seawater, sea breeze, soil, and so on. Stainless steel in the presence of chloride ions, corrosion, and even faster than ordinary low-carbon steel.

Therefore, the use environment of stainless steel is required, and it needs to be wiped regularly to remove dust and keep it clean and dry.

316 and 317 stainless steels (see below for properties of 317 stainless steel) are molybdenum-containing stainless steels.

The molybdenum content of 317 stainless steel is slightly higher than that of 316 stainless steel. Due to the molybdenum content in the steel, the overall performance of the steel is better than that of 310 and 304 stainless steel.

Under high temperature conditions, when the concentration of sulfuric acid is lower than 15% and higher than 85%, 316 Stainless steel has a wide range of uses. 316 stainless steel also has good chloride attack properties, so it is usually used in the marine environment.
