PH resistance of SS316 material
PH resistance of SS316 material
(OP)
I am curious about what will be the PH handling capacity of SS316 material. When pumps are made with SS304 manufacturers are recommending for a PH of 6.5 to 8.5.
Hence what will be the PH range for SS316 material.

And also i would like to know the corrossion resistance of SS304 against water with ferrous oxide.

For 304 the drop in pH of 1 is roughly equivalent to raising the Cl by 10x.
In 316 you have to drop the pH by 2 to see the same impact on pitting corrosion.
In other words, if 304 works at a specific temperature, Cl level and pH; then you could use 316 at the same temp, Cl level and a pH that is roughly 1 to 1.5 lower.
This is only a rough estimate. You need to know specifics before you can really talk about limits.
