Hastelloy C-4

Tilmaamaha Hastelloy C-4 iyo Guudmarka Codsiyada:
Daloolada waa daloolada nikkel-molybdenum-chromium ee austenitic-ka ah ee kaarboon yar. Farqiga ugu weyn ee u dhexeeya Nicrofer 6616 hMo iyo daloolada kale ee isku-dhafka kiimikada ee la midka ah ee hore loo sameeyay waa kaarboon yar, silikoon, bir iyo tungsten. Halabuurka kiimikadani wuxuu bixiyaa xasillooni aad u fiican 650-1040 ° C iyo iska caabin wanaagsan oo ku timaadda dalooshada intergranular, iyadoo laga fogaanayo u nuglaanshaha daxalka khadka geeska iyo daxalka alxanka HAZ xaaladaha wax soo saarka ee ku habboon. Daloolada loo isticmaalo nidaamyada desulfurization gaaska qiiqa, warshadda soo saarista iyo dib u soo noolaynta aashitada, aashitada acetic iyo wax soo saarka kiimikada beeraha, wax soo saarka titanium dioxide (habka kloride), dahaadhka elektrolytic.
Hastelloy C-4 Noocyo la mid ah:
NS335 (Shiinaha) W.Nr.2.4610 NiMo16Cr16Ti (Jarmalka)
Halabuurka kiimikada Hastelloy C-4:

Sifooyinka Jirka ee Hastelloy C-4:

Sifooyinka Farsamada Hastelloy C-4: (sifooyinka farsamada ugu yar ee 20 ℃):

Heerarka wax soo saarka Hastelloy C-4:

Waxqabadka iyo shuruudaha habka Hastelloy C-4:

1, Habka daaweynta kulaylka lama xiriirin karo baaruud, fosfooraska, rasaasta iyo biraha kale ee dhalaalka hooseeya, ama birta ayaa noqon doonta mid jajaban, waa in fiiro gaar ah loo yeesho in laga saaro sida rinjiga calaamadaynta, rinjiga tilmaamayaasha heerkulka, midabyada midabaysan, saliidaha, shidaalka iyo wasakhda kale. Inta ay ka yar tahay baaruudka shidaalka, waxa fiican in ka badan baaruudka gaaska dabiiciga ah, baaruudka gaaska dabiiciga ah waa inuu ka yar yahay 0.1%, baaruudka saliidda culus waa inuu ka yar yahay 0.5%. Kuleylka foornada korontada ayaa ah doorasho ka wanaagsan, sababtoo ah foornada korontada ayaa si sax ah u xakamayn karta heerkulka gaaska foornaduna waa nadiif. Haddii gaaska foornada gaaska uu ku filan yahay saafi, waad dooran kartaa.
2, heerkulka farsamaynta kulaylka ee daawaha ah oo ah 1080 ℃ ~ 900 ℃, habka qaboojinta ee qaboojinta biyaha ama qaboojinta kale ee degdega ah. Si loo hubiyo iska caabbinta ugu fiican ee daxalka, daaweynta kulaylka waa in la sameeyaa ka dib daaweynta kulaylka xalka.
