Key Features
Inconel® 600 Foil (Ni 72/Cr 16/Fe 8, UNS N06600) is a solid-solution-strengthened nickel-chromium alloy in thin flat sheet form, supplied in the Annealed temper:
Not Age-Hardenable: Stable Annealed Properties
Unlike precipitation-hardened Inconel grades, 600 is not age-hardenable. The Annealed temper delivers maximum ductility, good corrosion resistance, and consistent properties for forming and joining throughout the full thickness range.
Tensile Strength 600–1,200 MPa, Elongation 50%, Impact Toughness 160 J/m
High elongation and impact toughness make this foil well suited to thin-gauge components requiring tight bends and deep draws, where lower-ductility alloys would crack or delaminate during forming.
Melting Point 1,370–1,425 °C
The high melting range supports service in environments approaching 900 °C without risk of incipient melting or significant loss of structural integrity at peak service temperatures.
Oxidation Resistance to ~900 °C
Cr₂O₃ and NiCr₂O₄ surface oxides provide effective oxidation protection across the 700–900 °C range encountered in nuclear steam generator, furnace, and power generation shielding applications.
Performance in Reducing and Carburizing Atmospheres
The alloy retains its corrosion resistance in reducing and carburizing atmospheres encountered in chemical reactor liner and furnace muffle applications, where oxidizing-environment alloys would suffer rapid degradation.
Industrial Applications
Inconel® 600 Foil is used across nuclear, aerospace, chemical processing, and power generation industries wherever thin flat sheet must sustain oxidation and corrosion resistance at 700–900 °C:
- ✦ Heat Exchanger and Barrier Panels in Nuclear Steam Generators
- Used for heat exchanger and barrier panels in nuclear reactor steam generators, where Cr₂O₃ and NiCr₂O₄ oxide protection to ~900 °C and resistance to primary water corrosion determine material selection.
- ✦ Turbine Shroud Liner Elements
- Applied as turbine shroud liner elements, where the combination of high elongation for forming complex thin-gauge geometries and oxidation resistance at turbine operating temperatures are both required.
- ✦ Chemical Processing Reactor Liner in Reducing and Carburizing Atmospheres
- Used as reactor liner foil in chemical processing equipment operating in reducing and carburizing atmospheres, where 600’s resistance to these aggressive environments distinguishes it from oxidizing-service alternatives.
- ✦ High-Temperature Shielding in Aerospace and Power Generation
- Applied as shielding foil in aerospace and power generation systems where 700–900 °C oxidation resistance is the primary design requirement and thin-gauge formability is needed for complex shielding geometries.
- ✦ High-Temperature Oxidation Mechanism and Corrosion Research
- Used as a substrate for high-temperature oxidation mechanism studies, a model Ni-Cr alloy for oxide film formation and growth kinetics characterization, and a corrosion reference specimen for investigations in nuclear and chemical processing environments.
