    High Precision Nickel Alloy Steel UNS N0669 Blind Flanges For Construction


    GENERAL CHARACTERISTICS OF Alloy 690


    Alloy 690 is a high-chromium-nickel alloy with excellent resistance to many corrosive aqueous media and high-temperature atmospheres. It has


    high strength and good fabrication characteristics. The high chromium content imparts a resistance to oxidizing chemicals and high-temperature


    oxidizing gases. The high nickel gives resistance to stress corrosion cracking in chloride-containing environments and to sodium hydroxide


    solutions.

    Application


    The alloy finds applications involving processing of nitric acid and nitric/hydrofluoric acid solutions. As such it is used in tail-gas reheaters in nitric acid production and in heating coils and tanks for nitric/hydrofluoric acid solutions used to pickle stainless steels, and for the reprocessing of nuclear fuels.
    The alloy’s resistance to sulfur-containing gases makes it suitable for use in coal gasification units, burners and ducts for processing sulfuric acid.
    The alloy is further used for steam generator tubes, baffles and tube sheets as well as for hardware in nuclear power generation.


    WELDABILITY


    The alloy shows excellent weldability, and may be joined to other dissimilar metals and alloys using the appropriate filler metals. For extreme corrosive conditions, advice should be taken regarding the appropriate filler metal to be used.
