Hastelloy® C-276, which is also sold as Nickel Alloy C-276, is a nickel-molybdenum-chromium wrought alloy. Hastelloy C-276 is perfect for use in situations that demand protection from aggressive corrosion and localized corrosion attack. This alloy Other important features of Nickel Alloy C-276 and Hastelloy C-276 include its resistance to oxidizers like:
Ferric and cupric chlorides
Organic and inorganic hot contaminated media
Chlorine (wet chlorine gas)
Seawater
Acids
Hypochlorite
Chlorine dioxide
Hastelloy C-276 and Nickel Alloy C-276 Applications
As well, Nickel Alloy C-276 and Hastelloy C-276 is weldable with all common methods of welding (oxyacetylene is not recommended). Because of Hastelloy C-276’s outstanding corrosion resistant capabilities, it is used by a wide variety of industries for critical applications including:
Almost anything used around sulfuric acid (heat exchangers, evaporators, filters, and mixers)
Bleach plants and digesters for the manufacturing of paper and pulp
Components used around sour gas
Marine engineering
Waste treatment
Pollution control
