Ipayipi Elingenamthungo le-Inconel 625 – I-Nickel Alloy Efanele Ukugqwala Nokushisa Okuphezulu

Incazelo emfushane:

Uma usebenza ku-oyela negesi, ubunjiniyela basolwandle, ukucubungula amakhemikhali, noma izindiza, kungenzeka ukuthi uke wahlangana ne-Inconel 625. Ingenye yama-superalloy asekelwe ku-nickel asetshenziswa kakhulu emakethe. Abantu bayayikhetha uma bedinga into engamelana nokugqwala kanye nokushisa okuphezulu ngaphandle kokuwa.

Lesi sihloko sihlanganisa ukuthi iyini ipayipi elingenamthungo le-Inconel 625, yini eyenza ihluke kwezinye izinto, ukuthi isetshenziswa kuphi, yiziphi izindinganiso ezihlangabezana nazo, nokuthi yini okufanele uyazi ngaphambi koku-oda.

Iyini ipayipi elingenamthungo le-Inconel 625?

I-Inconel 625 (UNS N06625, W.Nr. 2.4856) iyi-alloy ye-nickel-chromium-molybdenum ene-niobium eyengeziwe. I-niobium isebenza ne-molybdenum ukuqinisa i-matrix ye-alloy, iyinike amandla aphezulu ngaphandle kokudinga ukwelashwa kokushisa okuqinisiwe. Lokho kuyinto enkulu - kusho ukuthi ungayishisela futhi uthole amandla aphelele ngaphandle kokwelashwa kokushisa okwengeziwe ngemva kokushisela.

Ipayipi elingenamthungo lisho ukuthi akukho mthungo ohlanganisiwe ubude. Lenziwa ngokubhoboza i-billet eqinile bese uyigoqa noma uyidwebe ibe usayizi. Ukungabikho komthungo ohlanganisiwe kusho ukuthi akukho ndawo ebuthakathaka, akukho bungozi bokugqwala komthungo, kanye nokuqina okungcono kokucindezela. Yingakho amapayipi angenamthungo eyisinqumo esizenzakalelayo sezinhlelo zokusebenza ezibalulekile lapho ukwehluleka kungeyona inketho.

Ipayipi elingenamthungo le-Inconel 625 lisebenza kusukela emazingeni okushisa acwebezelayo kuze kufike ku-982°C (1800°F). Limelana nokuqhekeka kwemigodi, ukugqwala kwemisele, kanye nokuqhekeka kokugqwala okucindezelwe yi-chloride — izinto ezintathu ezibulala amapayipi ajwayelekile ensimbi engagqwali enkonzweni yasolwandle kanye namakhemikhali.

Ukwakheka Kwamakhemikhali

Ukwakheka yikho okwenza i-Inconel 625 isebenze kahle. Nansi incazelo:

Isici	Isisindo %
I-Nickel (Ni)	58.0% min (ibhalansi)
I-Chromium (Cr)	20.0 – 23.0%
I-Molybdenum (Mo)	8.0 – 10.0%
I-Niobium + Tantalum (Nb + Ta)	3.15 – 4.15%
Insimbi (Fe)	Ubuningi obungu-5.0%
I-Manganese (Mn)	Ubuningi obungu-0.50%
I-Silicon (Si)	Ubuningi obungu-0.50%
Ikhabhoni (C)	Ubuningi obungu-0.10%
I-Cobalt (Co)	Ubuningi obungu-1.0%

Okuqukethwe okuphezulu kwe-nickel (58%+) yikho okwenza ukuthi ivikeleke kakhulu ekuqhekekeni kokugqwala kwe-chloride stress corrosion. I-molybdenum (8-10%) iyinika ukumelana okuhle kakhulu nokugqwala kwemigodi emanzini olwandle kanye nasemithonjeni equkethe i-chloride. I-niobium (3.15-4.15%) inikeza ukuqina kwesisombululo esiqinile.

Izakhiwo Zemishini

Esimweni esifakwe i-anneal, ipayipi elingenamthungo le-Inconel 625 linikeza lezi zakhiwo ezilandelayo ezijwayelekile zemishini:

Impahla	Inani
Amandla Okuqina (Okokugcina)	≥827 MPa (120 ksi)
Amandla Okukhiqiza (isilinganiso esingu-0.2%)	≥414 MPa (60 ksi)
Ukwelulwa (ngo-2″)	≥30%
Ubulukhuni	≤287 HB
Ubuningi	8.44 g/cm³
Indawo Yokuncibilika	1290 – 1350°C

Kusho ukuthini lokhu empeleni:I-Inconel 625 iqine ngokwanele ezinhlelweni zamapayipi anomfutho ophezulu futhi iqine ngokwanele ukusinda ekushayweni nasekudlidlizeni. Ukwelulwa okungenani okungu-30% kusho ukuthi ingagobeka futhi yakheke ngaphandle kokuqhekeka.

Emazingeni okushisa aphezulu, i-Inconel 625 igcina amandla awusizo afinyelela ku-982°C (1800°F). Iphinde ikwazi ukumelana kahle namazinga okushisa acwebezelayo — afinyelela ku--196°C — ngaphandle kokuqhekeka, yingakho uyibona ezinhlelweni ze-LNG kanye ne-nitrogen ewuketshezi.

Ukumelana Nokugqwala — Lapho Kukhanya Khona Ngempela

Lesi yisona sizathu esiyinhloko esenza abantu bakhokhe imali ephezulu ye-Inconel 625. Iphatha izindawo ezibhubhisa insimbi engagqwali engu-316L ngezinyanga.

Izindawo zasemanzini olwandle kanye nezasolwandle:I-Inconel 625 ayivikelekile ekugqwaleni kwamanzi olwandle. Iyamelana nokugqwala kwemigodi, ukugqwala kwemifantu, kanye nokungcoliswa kwezinto eziphilayo. Yingakho uyibona emapayipini okupholisa amanzi olwandle, ezinhlelweni zamanzi omlilo, emapayipini amanzi e-ballast, kanye nasemishinini yokukhiqiza ngaphansi kolwandle.

Ukuqhekeka kokugqwala kwe-chloride stress:Lokhu kuyingozi kakhulu ngensimbi engagqwali engu-304 kanye nengu-316 ekusetshenzisweni kwezasolwandle kanye namakhemikhali. I-Inconel 625 ayivikelekile ngokuphelele ngenxa yokuqukethwe kwayo okuphezulu kwe-nickel.

Ukumelana ne-asidi:I-Inconel 625 iphatha i-sulfuric acid, i-hydrochloric acid, i-phosphoric acid, ama-mixed acid, i-chlorine, izinyibilikisi ezine-chlorine, ama-fluoride, kanye nama-alkali aqinile. Ku-hydrofluoric acid vapor, izinga lokugqwala kwensimbi engagqwali engu-316L lingaba cishe izikhathi ezingu-65 kune-Inconel 625.

Ukumelana nokugoba:I-PREN (Pitting Resistance Equivalent Number) ye-Inconel 625 iphakeme kakhulu kune-316L. Kusisombululo se-10% FeCl₃ ku-65°C, i-316L ikhipha amapayipi kakhulu kuyilapho i-Inconel 625 ingathinteki nhlobo.

Isevisi ye-Sour (H₂S):I-Inconel 625 ivunyelwe isevisi emuncu ngokwe-NACE MR0175 / ISO 15156. Isetshenziswa kabanzi ekukhiqizweni kukawoyela negesi ogwini lolwandle kwezingxenye ezivezwe ku-hydrogen sulfide, i-carbon dioxide, kanye nama-chloride.

Amafomu kanye namazinga omkhiqizo

I-Inconel 625 itholakala ngezindlela eziningi zemikhiqizo. I-Womic Steel ihlinzeka ngazo zonke:

Ipayipi Nepayipi Elingenamthungo:I-ASTM B444 / ASME SB-444, AMS 5581

Inqubo Yokukhiqiza

I-Womic Steel ikhiqiza ipayipi elingenamthungo le-Inconel 625 ngenqubo elawulwayo:

Ukuncibilika:Ukuncibilikisa i-vacuum induction (VIM) noma i-vacuum arc remelting (VAR) kuqinisekisa okuqukethwe kwegesi okuphansi kanye nobumsulwa obuphezulu.
Ukubhoboza:I-billet eqinile iyashiswa futhi ibhobozwe ukuze yakhe igobolondo elingenalutho.
Ukukhipha noma ukugoqa okushisayo:Igobolondo elingenalutho lincishisiwe libe usayizi ophakathi nendawo.
Umdwebo obandayo:Ukudweba okubandayo okuningi okune-intermediate annealing kufeza ubukhulu bokugcina kanye nokubekezelelana okuqinile. Ukudweba okubandayo kuthuthukisa ukuqeda kobuso kanye nokunemba kobukhulu.
Ukufakwa kwesisombululo:Ukwelashwa kokugcina kokushisa ku-980-1040°C kulandelwe ukupholisa okusheshayo kubuyisela ukumelana nokugqwala kanye nokuqina.
Ukukhahlela kanye nokuphumula:Isusa isikali kanye ne-oxide, ishiye indawo ehlanzekile nengashintshi.
I-NDT kanye nokuhlolwa:Ukuhlolwa kwe-hydrostatic okungu-100%, ukuhlolwa kwe-ultrasonic, ukuhlolwa kwamanje kwe-eddy, kanye nokuhlolwa kobukhulu.

Kumapayipi ahlanganisiwe, inqubo isebenzisa umucu ogoqwe ngokubandayo owakhiwe futhi wahlanganiswa kusetshenziswa i-TIG noma i-plasma welding, kulandelwe yi-full solution annealing kanye ne-NDT yomthungo wokushisela.

Ukushisela Nokwenza

I-Inconel 625 yaziwa ngokushibilika okuhle kakhulu. Ungayishibilika usebenzisa i-TIG (GTAW), i-MIG (GMAW), i-stick welding (SMAW), i-laser welding, noma i-electron beam welding.

Insimbi yokugcwalisa enconyiwe:I-AWS A5.14 ERNiCrMo-3 (Ukugcwalisa kwe-Inconel 625)

Amaphuzu ayisihluthulelo okufanele uwakhumbule:

Akukho ukwelashwa kokushisa ngemva kokushiswa okudingekayo — i-alloy ithola amandla ayo ngokuqinisa isixazululo esiqinile, hhayi ukuqina kwemvula.
Hlanza indawo yokushisela kahle ngaphambi kokushisela — akukho uwoyela, amafutha, noma i-oxide.
Lawula ukufakwa kokushisa ukuze ugweme ukushisa ngokweqile.
Gcina izinga lokushisa eliphakathi kwe-interpass lingaphansi kuka-150°C.
Sebenzisa igesi yokuvikela i-argon noma i-argon-helium emsulwa.

Ngokushisela insimbi okuhlukile (i-Inconel 625 kuya ensimbini engagqwali noma ensimbini yekhabhoni), i-ERNiCrMo-3 nayo iyisigcwalisi esinconywayo.
