Inconel is an alloy that contains many nickels, and it is an anti-oxidation and corrosion-resistant material, which is very suitable for use in extreme environments subject to pressure and heat. When heated, Inconel will form a thick, stable passivation oxide layer to protect the surface from further erosion. Inconel maintains strength over a wide temperature range and is attractive for high-temperature applications where aluminum and steel creep due to thermally induced glass voids.
