Hastelloy C4 (Alloy C4, 2.4610, UNS N06455)

Alloy C-4 is a nickel-chromium-molybdenum alloy with outstanding high temperature stability. This alloy resists the formation of grain-boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process applications in the as-welded condition. Alloy C-4 alloy also has excellent resistance to stress-corrosion cracking and to oxidizing atmospheres up to 1900°F (1038°C).
