Inconel 600 vs Waspaloy
Side-by-side chemical composition and mechanical property comparison.
Overview
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.
Waspaloy
2.4654
Nickel-based gamma-prime strengthened superalloy — THE turbine disc material. Excellent creep-rupture strength up to 650°C (rotating) and 870°C (static). Developed 1950s by Pratt & Whitney. Triple-aged (solution + stabilize + precipitation) for peak properties. Superior to Inconel 718 above 650°C. Used for compressor and rotor discs, shafts, spacers, seals, rings, casings, and fasteners in gas turbine engines.
