Hastelloy C276 is a nickel-chromium-molybdenum alloy that has earned its reputation as one of the most corrosion-resistant materials available. It contains a balanced combination of chromium, molybdenum, and tungsten, which gives it resistance to oxidizing and reducing environments simultaneously—a rare feature among alloys.

In tube form, Hastelloy C276 provides versatility for a wide range of applications. Tubes are commonly used in piping systems, condensers, heat exchangers, scrubbers, and reactors where consistent exposure to corrosive chemicals is unavoidable. The alloy’s ability to resist stress corrosion cracking, pitting, and crevice attack ensures reliable service life even under the toughest conditions.
