Ikhoyili yensimbi engagqwali engu-321 eshisayo

Incazelo emfushane:

Insimbi engagqwali engu-321 iyinsimbi enamandla amakhulu, emelana kakhulu namazinga okushisa aphezulu kuno-316L. Inokumelana okungcono kokugqwala kuma-organic organic ekugxileni okuhlukile nasemazingeni okushisa ahlukahlukene, ikakhulukazi kwimidiya ye-oxidizing. Insimbi engagqwali engama-321 ivame ukusetshenziswa ekwenziweni kwamapayipi, iziqukathi ezingamelana ne-asidi kanye nemishini emelana nokugqoka.

Incazelo cishe nge-321 / 321H insimbi engagqwali nokuqhathanisa ne-304 ejwayelekile

Kokubili u-304 no-321 bangama-steels angenawuchungechunge angama-300 futhi banokuhluka okuncane ekumelaneni nokugqwala. Kodwa-ke, ezimweni ezingamelana nokushisa kuka-500-600 degrees Celsius, kusetshenziswa insimbi engagqwali engama-321. Ngaphezu kwalokho, insimbi emelana nokushisa iye yathuthukiswa ngokukhethekile phesheya futhi ibizwa nge-321H. Okuqukethwe yikhabhoni kuphakeme kancane kunalokho okungama-321, okufana ne-1Cr18Ni9Ti yasekhaya. Inani elifanelekile le-Ti lengezwa ku-insimbi engenasici ukwenza ngcono ukumelana nokugqwala kwangaphakathi. Lokhu kungenxa yokuthi esigabeni sokuqala sokukhiqizwa kwensimbi engagqwali, ngoba ubuchwepheshe bokuncibilikisa bebungephakeme ngokwanele ukunciphisa okuqukethwe yikhabhoni ensimbi, bekukwazi ukufeza lokhu ngokungeza ezinye izinto. Ngokuthuthuka kobuchwepheshe, kuye kwenzeka ukukhiqiza izinhlobo zensimbi engagqwali enekhabhoni ephansi kanye ne-ultra-low-carbon. Ngakho-ke, kusetshenziswe kabanzi izinto ezingama-304. Ngalesi sikhathi, izici zokumelana nokushisa kwe-321 noma i-321H noma i-1Cr18Ni9Ti ziyabonakala.

I-304 iyi-0Cr18Ni9Ti, i-321 isuselwe ku-304 kanye ne-Ti ukuthuthukisa ukuthambekela kokugqwala okungaphakathi.

Insimbi engagqwali engu-321 okukhona kuyo iTi njengento yokuzinzisa, kepha futhi iyizinhlobo zensimbi enamandla ashisayo, ingcono kakhulu kune-316L ekushiseni okuphezulu. Insimbi engagqwali engama-321 kuma-organic organic wokugxila okuhlukile, amazinga okushisa ahlukene, ikakhulukazi ekumelaneni ne-oxidizing Medium ukumelana nokuhuzuka okuhle, okusetshenziselwa ukwenza amalayili nokuhambisa amapayipi eziqukathi ze-asidi ezingamelana nokugqoka kanye nemishini emelana nokugqoka.

Insimbi engagqwali engu-321 iyi-Ni-Cr-Mo yohlobo lwensimbi engenasici, ukusebenza kwayo kufana kakhulu no-304, kepha ngenxa yokwengezwa kwe-titanium yensimbi, inokumelana kangcono nokugqwala komngcele okusanhlamvu namandla okushisa aphezulu. Ngenxa yokwengezwa kwe-titanium yensimbi, ilawula ngempumelelo ukwakheka kwe-chromium carbide.

Insimbi engagqwali engu-321 inokusebenza okuhle kokucindezeleka kokuqhekeka kanye nokumelana nokushisa okuphezulu (i-Creep Resistance) izakhiwo zokuxineka zingcono kunezinsimbi ezingama-304.
