Haynes 230 vs Inconel 601
Side-by-side chemical composition and mechanical property comparison.
Overview
Haynes 230
2.4733
Nickel-chromium-tungsten alloy — THE combustor can material for gas turbines. Outstanding oxidation resistance to 1149°C for prolonged exposure. Excellent long-term thermal stability (no sigma/mu phase after 16000h at 649-870°C). Lower thermal expansion than most high-temp alloys. Lanthanum addition improves oxide scale adherence. Used for gas turbine combustion cans, transition ducts, furnace retorts, and catalyst grids in nitric acid production.
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.
