Hastelloy C276 EN10276 Seamless Nickel Alloy Pipe with 15-17% Molybdenum and 690 N/mm² Tensile Strength
Hastelloy C-276 nickel alloy seamless pipes offer exceptional performance in chemical processing environments containing both oxidizing and reducing media. The high molybdenum (15-17%) and chromium (14.5-16.5%) content provides excellent resistance to chloride corrosion, while tungsten (3-4.5%) enhances overall corrosion resistance capabilities.
This alloy is one of the few materials capable of withstanding corrosion from chlorine, hypochlorite, and chlorine dioxide, demonstrating outstanding performance in high-concentration chloride environments including ferric chloride and copper chloride.
