Hastelloy X vs Inconel 600
Side-by-side chemical composition and mechanical property comparison.
Overview
Hastelloy X
2.4665
Nickel-chromium-iron-molybdenum solid-solution superalloy — exceptional combination of oxidation resistance, fabricability, and high-temperature strength. NOT age-hardenable (solid-solution only). Oxidation-resistant to 1200°C, good ductility after 16000h at 650-870°C. Outstanding formability and weldability for a superalloy. Used for gas turbine combustor cans, transition ducts, afterburners, furnace hardware, and petrochemical process equipment.
Inconel 600
2.4816
Nickel-chromium-iron alloy — the standard engineering material for combined heat and corrosion resistance. Not precipitation hardenable. Virtually immune to chloride-ion stress corrosion cracking. Service from cryogenic to 1095°C. Used for furnace components, nuclear steam generators, chemical plant equipment, and food processing.
