Hastelloy C276 flanges are premium industrial components engineered from a corrosion-resistant nickel-molybdenum-chromium alloy. Known for their exceptional durability in aggressive chemical environments, these flanges are essential in applications where ordinary stainless steel or other alloys fail due to pitting, crevice corrosion, or stress corrosion cracking.
Hastelloy C276 (UNS N10276) is a well-established superalloy containing nickel, molybdenum, chromium, iron, and tungsten. This precise combination of elements gives it unique corrosion resistance properties, especially in environments containing strong oxidizers and reducers. It's particularly effective against chlorides, wet chlorine gas, hypochlorite, and acid mixtures.
The primary reason engineers choose Hastelloy C276 flanges is their outstanding resistance to a broad range of corrosive chemicals. These flanges resist pitting, crevice corrosion, and stress corrosion cracking, even in highly acidic and high-temperature environments. They are ideal for applications involving sulfuric acid, hydrochloric acid, phosphoric acid, and acetic acid.
Due to their high-performance characteristics, Hastelloy C276 flanges are widely used across industries such as chemical processing, petrochemical refining, marine engineering, waste treatment, pulp and paper, and pollution control systems. They are commonly installed in heat exchangers, reactors, pressure vessels, piping systems, and valves exposed to aggressive chemical flow.
