Hastelloy X per MSRR 7127 Nickel Alloy
MSRR 7127 is a Rolls Royce specification for Hastelloy X.
HASTELLOY X (UNS N06002) is a nickel-chromium-iron-molybdenum alloy that possesses an exceptional combination of oxidation resistance, fabricability and high-temperature strength. It has also been found to be exceptionally resistant to stresscorrosion cracking in petrochemical applications. X alloy exhibits good ductility after prolonged exposure at temperatures of 1200, 1400, 1600°F (650, 760 and 870°C) for 16,000 hours
