Inconel 600 or 601 Bolts For High Temperatures?

Q: For a high temperature oxidation-rich environment which would be better Inconel 600 or 601 bolts?
A: For this situation it really depends on the temperature range you are dealing with because both an Inconel 600 bolt and an Inconel 601 bolt offer good oxidation resistance. Inconel 600 can service up to 2000F where Inconel 601 can handle up to 2200F. If you temperatures aren’t that severe, I’d suggest A286 bolts for excellent oxidation resistance. An A286 bolt is known for its high strength, creep resistance and oxidation resistance up to 1300F.

Inconel 625 for Oxidation Resistance and Acid Contamination

Q: I have a process that is running at high temperatures that can fluctuate up to 1500F that requires not only oxidation resistance but also some chemical resistance contaminants. I had tried some C276 bolts for the stray acids but they don’t seem to be working mechanically…suggestions?

A: A good bolt to try may be an Inconel 625 bolt. They can handle much higher temperatures up to about 1800F. These Inconel bolts also can provide excellent oxidation resistance and can also provide protection against reducing chemicals like stray acid contaminants.
