Lifespan is limited. Compared with uniform corrosion (chemical corrosion), localized corrosion (electrochemical corrosion) is much faster and more dangerous, often leading to leakage failure. In the aqueous medium containing Cl-, the weakest link of the stainless steel water tank is the welding area. Because this area has been subjected to high temperature heating, the structure and performance are deteriorated, and the corrosion resistance is also reduced.
