Inconel 600 vs Monel 400
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.
Monel 400
2.4360
Nickel-copper alloy with excellent resistance to seawater, hydrofluoric acid, and alkaline environments. One of the few alloys resistant to HF acid at all concentrations. Used for marine engineering, chemical processing, oil refinery piping, and valve/pump components.
