Hastelloy˘ C-4

Available in any of the 'profile options'

This Nickel-Chromium-Molybdenum alloy tolerates high temperatures and gives a design freedom in areas where weld geometry makes excessive heat build-up unavoidable. Resistance to general and localised corrosion and stress corrosion cracking is generally similar to Hastelloy C-276.

Hastelloy C-4 is also known as Nicrofer 6616.
