Tlhaloso ea Sehlahisoa
Ka mor'a ho eketsa Ti e le ntho e tsitsitseng, tšepe e sa hloekang ea 321 e bonts'a matla a maholo a chesang, a molemo ho feta tšepe ea 316L.E na le khanyetso e ntle ka ho fetesisa ho li-acid tse fapaneng tsa organic le inorganic esita le maemong a fapaneng le mocheso.Ho feta moo, tšepe ea mofuta oa 321 e sebetsa hantle haholo libakeng tse nang le oxidizing.Sena se etsa hore e be se loketseng bakeng sa ho etsa likepe tse hanyetsanang le asiti, masela a lisebelisoa le liphaephe.
Sebopeho sa tšepe e sa hloekang ea 321 se kenyelletsa nickel (Ni), chromium (Cr) le titanium (Ti), e leng motsoako oa tšepe e sa hloekang ea austenitic.E ts'oana le tšepe e sa hloekang ea 304 e nang le thepa e tšoanang.Leha ho le joalo, ho eketsoa ha titanium ho ntlafatsa khanyetso ea eona ea kutu ho ea ka meeli ea lijo-thollo le ho matlafatsa matla a eona mochesong o phahameng.Ho eketsoa ha titanium ka katleho ho thibela ho thehoa ha chromium carbides ka alloy.
321 tšepe e sa hloekang e na le thepa e ntle haholo mabapi le ho phatloha ho hoholo ha khatello ea mocheso le khanyetso ea creep.Thepa ea eona ea mochini tlas'a maemo a phahameng a mocheso a feta a 304 tšepe e sa hloekang.Ka hona, e loketse bakeng sa lits'ebetso tsa welding tse kenyelletsang likarolo tse sebetsang ka mocheso o phahameng.

Q1: Ho thoe'ng ka litefiso tsa ho romella?
Litšenyehelo tsa ho romella li angoa ke lintlha tse ngata.Haeba nako e le ea bohlokoa, ho fana ka maikutlo ke khetho e ntle ka ho fetisisa, leha e le ka theko e phahameng.Bakeng sa bongata bo boholo, thepa ea leoatleng ke khetho e loketseng haholoanyane, le hoja e nka nako e telele.Ho fumana quote e nepahetseng ea thomello ho nahanoa ka bongata, boima, mokhoa le sebaka seo u eang ho sona, ka kopo ikopanye le rona.
Q2: Litheko tsa hau ke life?
Ka kopo hlokomela hore litheko tsa rona li ka fetoha ka lebaka la lintlha tse kang phepelo le maemo a 'maraka.Ho netefatsa hore o fumana lintlha tse nepahetseng ka ho fetesisa le tsa morao-rao mabapi le litheko, re u kopa ka mosa hore u ikopanye le rona ka kotloloho.Re tla thabela ho u fa lenane le ntlafalitsoeng la litheko.Ke leboha tšebelisano 'moho le kutloisiso ea hau.
Q3: Na u na le palo e tlase ea odara?
Haeba o batla lintlha tse ling mabapi le litlhokahalo tse tlase tsa odara bakeng sa lihlahisoa tse ikhethileng tsa machabeng, ka kopo ikutloe u lokolohile ho ikopanya le rona.Re mona ho u thusa le ho u fa lintlha tse hlokahalang.Ka kopo, ikutloe u lokolohile ho ikopanya le rona ha ho u thusa.
