    Weight(%)58.0 min27.0~31.07.0~11.00.05 max0.50 max0.50 max0.15 max0.50 max

    Advantages

    • Excellent resistance to many corrosive aqueous media and hightemperature atmospheres.
    • High strength, good metallurgical stability, and favorable fabrication characteristics.
    • Outstanding resistance to oxidizing chemicals and to high-temperature oxidizing gases.
    • Resistance to stresscorrosion cracking in chloride-containing environments as well as to sodium hydroxide solutions.

    Application

    • Inconel 690 is widely used for steam generator tubes, baffles, tubesheets, and hardware in nuclear power generation.
    • Useful for various applications involving nitric or nitric/hydrofluoric acid solutions.
    • Examples are tail-gas reheaters used in nitric acid production and heating coils and tanks for Nitric/hydrofluoric solutions used in pickling of stainless steels and reprocessing of nuclear fuels
    • Coal-gasification units, burners and ducts for processing sulfuric acid, furnaces for petrochemical processing, recuperators, incinerators, and glass vitrification equipment for radioactive waste disposal.
