Hastelloy C-4
Sharaxaad Gaaban:
Hastelloy C-4 (UNS NO6455)
Tilmaamaha Hastelloy C-4 iyo Dulmarka Codsiyada:
Daawaha waa austenitic-kaarboon-yar nikkel-molybdenum-chromium alloy. Farqiga ugu weyn ee u dhexeeya Nicrofer 6616 hMo iyo alloysyada kale ee isku midka ah ee kiimikada hore loo sameeyay waa kaarboon yar, silikoon, birta iyo tungsten. Halabuurka kiimikadani wuxuu bixiyaa xasillooni heer sare ah oo ah 650-1040 ° C iyo iska caabbinta wanaajinta ee daxalka intergranular, ka fogaanshaha u nuglaanshaha daxalka khadka iyo alxanka HAZ ee xaaladaha wax soo saarka ee ku habboon. Alloy loo isticmaalo nidaamka desulfurization gaaska flue, pickling iyo warshad dib u soo kabashada acid, acetic acid iyo wax soo saarka kiimikooyinka beeraha, titanium dioxide wax soo saarka (hab chloride), dahaadhay electrolytic.

Hastelloy C-4 waxqabadka iyo shuruudaha:
1, In geeddi-socodka daaweynta kulaylku ma la xiriiri karaan baaruud, fosfooraska, hogaanka iyo biraha kale dhibic dhalaalaysa hoose, ama daawaha noqon doonaa mid jajaban, waa in fiiro gaar ah in meesha laga saaro sida calaamadaynta rinjiga, rinjiga tilmaamayaasha heerkulka, crayons midabka, saliidaha, shidaalka. iyo wasakh kale. Maaddada baaruudda hoose ee shidaalka ayaa ka sii fiican, maadada baaruud ee gaaska dabiiciga ah waa in ay ka yar tahay 0.1%, maadada baaruud ee saliidda culus waa in ay ka yar tahay 0.5%. Kuleylinta foornada korontada ayaa ah doorasho ka fiican, sababtoo ah foornada korontada ayaa si sax ah u xakameyn karta heerkulka iyo gaaska foornada waa nadiif. Haddii shooladda gaasku ay saafi tahay, waad dooran kartaa.
2, alloy heerkulka processing kulaylka kala duwan ee 1080 ℃ ~ 900 ℃, habka qaboojinta biyaha qaboojinta ama qaboojinta kale degdeg ah. Si loo hubiyo caabbinta daxalka ugu fiican, daaweynta kulaylka waa in la sameeyaa ka dib daaweynta kulaylka xalalka.
