Metal that does not corrode in low pH
Metal that does not corrode in low pH
(OP)
I have a small concrete monitoring weir at a mine site. A 20 mm thick metal plate with a V-notch is required to measure water levels. What is the best type of metal to be used for this application so that the metal does not corrode in the low pH mine water.

a stainless steel could be a solution but it will be necessary to have more info on water chemistry, ph, design life?

If they are below 5,000 ppm try 2205. It is strong enough to give you some erosion resistance also.

a) 2205
b) AL-6XN, 1925hMo, 26-6Mo, 2507, Zeron 100
c) C-276, C-22, 59, 686
In that order of increasing corrosion resistance.
