Q: Does Inconel rust?
A: Inconel bolt grades 625 and 718 are not only used for the unique high strength / high temperature properties, but they also offer excellent corrosion resistance, almost comparable to Hastelloy. This means Inconel bolts won’t rust or corrode in many harsh chemicals, and acids, and are almost inert to mild environments, such as sea water, neutral salts, and alkaline media.
