Hastelloy and Nitric Acid

Q: Can I use Hastelloy C276 bolts for protection from Nitric Acid?
A: Typically this is not recommended. Though C276 bolts are highly corrosion resistant to many acids, it is not very resistant to strong oxidizers like nitric acid. Materials with higher chromium content like Incoloy and possibly Hastelloy C22 tend to be more effective to oxidizing media.
