Ingxubevange 625 (UNS N06625)
Isifinyezo	Ingxubevange ye-nickel-chromium-molybdenum enokwengezwa kwe-niobium esebenza ne-molybdenum ukuze iqinise i-matrix ye-alloy futhi ngaleyo ndlela inikeze amandla aphezulu ngaphandle kokwelashwa okuqinisa ukushisa. Ingxubevange imelana nezinhlobonhlobo zezindawo ezigqwala kakhulu futhi imelana ikakhulukazi nokugqwala nokugqwala kwemifantu. Isetshenziswa ekucubunguleni amakhemikhali, i-aerospace kanye nobunjiniyela basolwandle, izinto zokulawula ukungcoliswa kwemvelo, kanye neziphehlisi zenuzi.
Amafomu Omkhiqizo Ajwayelekile	Ipayipi, ishubhu, ishidi, umucu, ipuleti, ibha eyindilinga, ibha eyisicaba, isitokwe sokubumba, ihexagon nocingo.

I-Microstructure

I-alloy 625 iyingxube ye-solid-solution matrix-stiffened face-centered-cubic alloy.
Izinhlamvu

Ngenxa yokuqukethwe kwebhokisi eliphansi kanye nokwelashwa kokushisa okuzinzile, i-Inconel 625 ibonisa ukuthambekela okuncane kokuzwela ngisho nangemva kwamahora angu-50 emazingeni okushisa ebangeni elingu-650~450℃.

Ingxubevange inikezwa esimweni esithambile sokusetshenziswa okubandakanya ukugqwala okumanzi (Ingxubevange engu-625, ibanga loku-1), futhi igunyazwe i-TUV yemikhumbi yokucindezela ebangeni lokushisa -196 kuya ku-450℃.

Ngezinhlelo zokusebenza zezinga lokushisa eliphezulu, ngaphezu kwe-approx. 600℃ , lapho kudingeka khona amandla aphezulu nokumelana nokukhasa nokuqhekeka, inguqulo efakwe kwisisombululo (Ingxubevange 625, ibanga lesi-2) enokuqukethwe kwekhabhoni ephezulu ivame ukusetshenziswa futhi itholakale uma icelwa kwezinye izinhlobo zemikhiqizo.

Ukumelana okuvelele kokugoba, ukugqwala kwe-crevice, nokuhlasela kwe-intergranular;

Cishe ukukhululeka okuphelele ekuqhekekeni kwe-chloride-induced stress-corrosion;

Ukumelana okuhle nama-acids amaminerali, njenge-nitric, i-phosphoric, i-sulfuric ne-hydrochloric acids;

Ukumelana kahle nama-alkali nama-asidi e-organic;

Izakhiwo ezinhle zemishini.
Ukumelana Nokugqwala

Okuqukethwe okuphezulu kwe-alloy ye-alloy 625 kuyenza ikwazi ukumelana nezinhlobonhlobo zemvelo yokugqwala. Ezindaweni ezithambile ezifana nomkhathi, amanzi ahlanzekile nawolwandle, usawoti ongathathi hlangothi, kanye nemithombo ye-alkaline cishe akukho ukuhlasela. Esimeni sokugqwala esibi kakhulu inhlanganisela ye-nickel ne-chromium inikeza ukumelana namakhemikhali e-oxidizing, kuyilapho okuqukethwe kwe-nickel ephezulu ne-molybdenum kunikeza ukumelana ne-nonoxidizing ngokumelene nokuzwela ngesikhathi sokushisela, ngaleyo ndlela kuvimbele ukuqhekeka okulandelayo kwe-intergranular. Futhi, okuqukethwe kwe-nickel ephezulu kuhlinzeka ngokuqhekeka kwe-chloride ion-stress-corrosion.
Izinhlelo zokusebenza

Inguqulo ethambile ye-Alloy 625 (ibanga loku-1) ikhethwa uma isetshenziswa embonini yezinqubo zamakhemikhali, kwezobunjiniyela basolwandle kanye nasezinsizeni zokulawula ukungcola ukuze kuvikelwe imvelo. Izinhlelo zokusebenza ezijwayelekile yilezi:

1. Imishini yokukhiqiza i-superphosphoric acid;

2. Imishini yokulungisa kabusha imfucuza yenuzi;

3. Amashubhu okukhiqiza igesi emuncu;

4. Amapayipi amapayipi kanye nokushiswa kwezikhuphukeli ekuhloleni uwoyela;

5. Imboni yasogwini kanye nempahla yasolwandle;

6. Izingxenye ze-flue gas scrubber kanye ne-damper;

7. Ushimula linings.
Ekufakweni kwezinga lokushisa eliphezulu, kufika cishe ku-1000℃, inguqulo efakwe isisombululo ye-Alloy 625 (ibanga lesi-2) ingasetshenziswa ngokuvumelana nekhodi ye-ASME yemikhumbi yokucindezela. Isicelo esijwayelekile yilezi:

 

1. Izingxenye ohlelweni lwegesi eyimfucuza kanye nezindawo zokuhlanza igesi engcolile ezichayeka emazingeni okushisa aphezulu;

2. Izitaki ezivuthayo ezindaweni zokucwenga kanye nezinkundla zasogwini;

3. I-recuperator kanye nezinxephezelo;

4. Isistimu yokukhipha umoya wenjini ye-diesel;

5. Amashubhu okushisa aphezulu ezitshalweni zokushiswa kwemfucuza.
