Which type of stainless steel tank can dichloromethane be stored in?

dichloromethane will decompose at high temperature or under illumination, resulting in chloride ions. Generally, stainless steel is not resistant to chloride ions, and pitting corrosion will occur, such as 34. If stainless steel must be used to store varieties that must be resistant to chloride ions, consider using 316L, which has better resistance to chloride ions.
