Hastelloy® C-276

Hastelloy® C-276 is one of the most widely specified corrosion-resistant nickel alloys for severe mixed-chemistry environments. It is used where wet chlorides, oxidizers, reducers, and localized corrosion risks all have to be addressed with one material. EQI supplies HASTELLOY C-276 for process-critical components and fabricated hardware.
