Butt-welding Pipe Fittings Hastelloy x 2.4665 Stub End
HASTELLOY X is a wrought nickel-based alloy with excellent high temperature strength and oxidation resistance. All product forms are excellent in forming and welding. Although HASTELLOY X is primarily known for its heat and oxidation resistance, it also has good resistance to chloride stress corrosion cracking and good carburization, as well as excellent resistance to reducing or carburizing atmospheres. Alloy X is one of the most widely used nickel-based superalloys for gas turbine engine components.
Hastelloy X is especially recommended for furnace applications due to its unusual resistance to oxidizing, reducing and neutral atmospheres. Hearth rolls made from this alloy are still in good condition after 8,700 hours of operation at 2150¡ãF (1177¡ãC).
Alloy X also excels in jet engine exhaust pipes, afterburner components, cabin heaters and other aircraft parts.
This nickel steel alloy has excellent resistance to stress corrosion cracking in petrochemical applications. The matrix hardening provided by the molybdenum content results in high strength of solid solution alloys with good manufacturing properties.
