Product information for purchasing teams
Hastelloy C276 is a nickel-molybdenum-chromium alloy with tungsten. It is one of the most corrosion-resistant alloys available, handling wet chlorine, hypochlorite, ferric and cupric chlorides and mixed acids, and its very low carbon lets it be used as-welded.
