Can I use Hastelloy bolts in a combination of salt water and acid? I have salt water process that has some sulfuric acid contamination? Can it handle this? Temperature would be around 100F.
A: Yes, Hastelloy bolts are virtually inert to salt water environments and the combination of salt water and sulfuric acid won’t be a problem. Hastelloy bolts provide protection to sulfuric acid at this temperature, even at 80% concentration. Here is a chart that can demonstrate their resistance to sulfuric acid corrosion. https://www.extreme-bolt.com/
