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.
