Is C-276 a Hastelloy?
HASTELLOY C276 is a nickel-chromium-molybdenum wrought alloy considered the most versatile corrosion-resistant alloy. The alloy resists the formation of grain boundary precipitates in the welding heat affected zone and is therefore suitable for most chemical process applications under welding conditions. Alloy C-276 also provides excellent resistance to pitting corrosion, stress corrosion cracking, and oxidizing atmospheres up to 1900°F. Alloy C-276 offers excellent resistance to a wide range of chemical environments.
