Which stainless steel grade has better resistance to chloride ions? How much chloride can 304 withstand?
Previously, 316L was used for experiments, but later Hastelloy was adopted instead； In another experiment, zirconium material was used first, followed by titanium material
For materials such as duplex steel and titanium, in general tests on 304 steel require chloride ions in water to be less than 25 ppm
304 and 316 basically don’t work. 2205 is pretty good; if you want something better, go with titanium materials
At 40 degrees, 304 steel can resist pitting in the presence of 150 PPM chloride ions. 904L is more resistant to chloride ions; at 40 degrees Celsius, it can withstand pitting at 10,000 PPM
The price is a little over three times that of 304.
