316Ti and 904L are corrosion-resistant
Thread Content
I would like to ask everyone: in the presence of hydrobromic acid at 1000 ppm, which material is more corrosion-resistant, 316Ti or 904L? ?
Temperature? Conduct intergranular corrosion tests!
Just apply our 711 inorganic anti-corrosion coating directly
Our previous company built similar hydrogen bromide solution storage tanks; initially 316L material was used, but perforations occurred when 2205 test plates were immersed in the solution. TA2 was tried as well, with no success, and in the end conductive halon was sprayed on.
Run an experiment to compare the weight and corrosion rate
It is generally believed that 904L is slightly better

Generally speaking, 904L is slightly better than 316, but there are no data available for this temperature. As mentioned above, if a metal must be used, it’s best to conduct a test; I can provide test specimens if needed.
