321 Ishidi Lensimbi Engagqwali 2b Ba Qeda

Incazelo emfushane:

1. Eyensimbi engagqwali ekwazi ukumelana nokushisa
2. Isetshenziselwa imishini yangaphandle evulekile embonini yamakhemikhali, amalahle kanye ne-petroleum enezidingo zokumelana nokugqwala komngcele wokusanhlamvu, izingxenye eziphikisana nokushisa zezinto zokwakha kanye nezingxenye ezinzima ekwelapheni ukushisa.
3. Ukupakisha: i-pallet yokhuni noma ikesi lezinkuni
4. Indlela yokuthutha: umoya noma ulwandle

Incazelo

I-alloy 321 (UNS S32100) iyipuleti lensimbi engagqwali elizinzile elinikeza njengenzuzo enkulu ukumelana nokugqwala kwe-intergranular kulandela ukuchayeka emazingeni okushisa ebangeni lemvula ye-chromium carbide ukusuka ku-800 kuya ku-1500°F (427 kuya ku-816°C).I-alloy 321 ipuleti lensimbi engagqwali lizinzile ngokumelene nokwakheka kwe-chromium carbide ngokungezwa kwe-titanium.

I-alloy 321 ipuleti lensimbi engagqwali nayo inenzuzo ensizakalweni yokushisa okuphezulu ngenxa yezakhiwo zayo ezinhle zomshini.I-alloy 321 insimbi engagqwali ipuleti linikeza izakhiwo ezikhuphukayo nezikhuphuka ingcindezi kune-Alloy 304 futhi, ikakhulukazi, i-Alloy 304L, engase futhi icatshangelwe ukuchayeka lapho ukuzwela nokugqwala kwe-intergranular kuwukukhathazeka.

Ipuleti lensimbi engagqwali engu-321 ye-Ti njengento yokuzinzisa ikhona, kodwa futhi iyibanga lensimbi eshisayo, ekushiseni okuphezulu kungcono kunepuleti lensimbi engagqwali engu-316 l.Ipuleti lensimbi engagqwali engu-321 ekugxiliseni okuhlukile kanye nezinga lokushisa le-asidi ephilayo kanye ne-asidi ye-inorganic, ikakhulukazi endaweni ye-oxidizing inokumelana okuhle nokuhunyazwa, esetshenziswa ekwenzeni iziqukathi nemishini ye-asidi engagugi.

Ipuleti lensimbi engagqwali engu-321 iyipuleti lensimbi ye-Ni-Cr-Mo austenitic yensimbi engenasici, ukusebenza kwayo kufana kakhulu nepuleti lensimbi engagqwali engu-304, kodwa ngenxa yokwengezwa kwensimbi ye-titanium, inokumelana nokugqwala komngcele wokusanhlamvu okungcono namandla okushisa aphezulu.Ukwakhiwa kwe-chromium carbide kulawulwa ngokuphumelelayo ngokungeza i-titanium metal.
