Inconel 601 vs Monel 400
Side-by-side chemical composition and mechanical property comparison.
Overview
Inconel 601
2.4851
Nickel-chromium-iron alloy with aluminum for outstanding high-temperature oxidation resistance up to 1200°C. The Al forms a protective oxide scale resistant to spalling under cyclic thermal conditions. Better oxidation resistance than Inconel 600 (which lacks Al). Used for furnace hardware (baskets, trays, fixtures), radiant tubes, thermocouple protection tubes, catalyst support grids, and thermal reactors in automotive exhaust systems.
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.
