INCONEL® aloyi 690(UNS N06690/W. Nr. 2.4642) ndi aloyi ya nickel ya chromium yapamwamba yomwe imalimbana bwino ndi zinthu zambiri zowononga zamadzimadzi komanso kutentha kwambiri.Kuphatikiza pa kukana kwa dzimbiri, aloyi 690 ili ndi mphamvu zambiri, kukhazikika kwazitsulo bwino, komanso mawonekedwe abwino opanga.
The Inconel Alloy 690 Pipe & Tube imapereka kukana kwakukulu kwamitundu yosiyanasiyana yazambiri zowononga monga chloride ion stress cracking komanso imapereka kutentha kwambiri komanso kumayambitsa kukana kwa okosijeni.
Inconel Alloy 690 Pipe & Tube ndi austenite nickel-chromium-based superalloys grade chubu, chubu, chitoliro & tubular mankhwala ku Mafuta ndi Gasi, Nyukiliya Ndi Mphamvu, Mphamvu Generation, Azamlengalenga, Process Industries & Refining, General Industrial, Chemical Process, Medical , Kuyera Kwambiri ndi Kuchita Kwapamwamba.Inconel Alloy 690 Pipe & Tube ndizoyenera kugwiritsidwa ntchito m'malo ovuta kwambiri omwe ali ndi mphamvu komanso kutentha.

Kutentha ndi pickling
Mofanana ndi ma aloyi ena a faifi tambala, aloyi 690 iyenera kukhala yoyera isanatenthedwe ndipo iyenera kutenthedwa mumlengalenga wopanda sulfure.Mng'anjo wa ng'anjo kuti utenthetse wotseguka uyeneranso kuchepetsedwa pang'ono kuti zinthu zisakhale ndi okosijeni wambiri.
INCONEL alloy 690 ndi alloy-solution alloy ndipo sawumitsa ndi chithandizo cha kutentha.Alloy nthawi zambiri amagwiritsidwa ntchito ngati annealed.
Kupanga
Kutentha kosiyanasiyana kwa kupanga kotentha kwambiri kwa INCONEL alloy 690 ndi 1900 mpaka 2250 ° F (1040 mpaka 1230 ° C).Kupanga kuwala kumatha kuchitidwa pa kutentha mpaka 1600 ° F (870 ° C).
Microstructure
INCONEL alloy 690 ndi austenitic, solid-solution alloy yokhala ndi kukhazikika kwazitsulo.Aloyi imakhala ndi kusungunuka kochepa kwa carbon, ndipo microstructure yake imakhala ndi carbides.Carbide yayikulu yomwe ilipo mu aloyi ndi M23C6;kuchuluka kwa gawoli kumasiyanasiyana ndi zomwe zili ndi kaboni komanso kukhudzana ndi kutentha kwa zinthuzo.Magawo ena omwe amapezeka nthawi zambiri ndi titanium nitrides ndi carbonitrides.Palibe magawo osakanikirana a intermetallic monga gawo la sigma omwe adadziwika mu alloy 690.
