Hastelloy C-276 vs Inconel 601
Side-by-side chemical composition and mechanical property comparison.
Overview
Hastelloy C-276
2.4819
The most versatile corrosion-resistant alloy available. Ni-Mo-Cr-W composition resists both oxidizing and reducing environments. Outstanding resistance to pitting, stress corrosion cracking, and wet chlorine gas. Used in chemical processing, flue gas desulfurization, pulp & paper, and waste treatment.
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.
