Litšobotsi tsa Ferritic Stainless Steel

1 sepakapakeng ts'enyeho hanyetsa ferritic celik

Kaha tšepe e sa hloekang ea ferritic e na le ts'ireletso e ntle ea sepakapaka, e 'nile ea sebelisoa e le marulelo le marako a likharetene tsa meaho haufinyane. Leha ho le joalo, tikoloho ea sepakapaka libakeng tse haufi le leoatle e thata haholoholo, haholo-holo likaroloana tse emisitsoeng leoatleng le moeeng ke lintho tse senyang haholo. Ka hona, tšepe e sa hloekang ea chromium ferritic e sebelisitsoeng libakeng tsena e se e entsoe. Lisebelisoa tse se nang tšepe tse sa keneleng ts'enyeho ea sepakapaka li na le chromium e phahameng le molybdenum e phahameng, mme ho eketsoa palo e nyane ea niobium le titanium. Ts'epe ena e hlile e na le 22% chromium le 1.2% molybdenum. Chromium e lekaneng le molybdenum li bohlokoa ho ntlafatsa pente ea tšepe e sa hloekang. Mofuta oa 304 le 316 austenitic stainless steel steels o na le keketseho e kholo sebakeng sa mafome le keketseho ea palo ea potoloho ea liteko tsa ts'enyeho ea cyclic. Ho fapana le moo, bakeng sa litšepe tse sa hloekang tsa ferritic tse kang mofuta oa 444 le tšepe ea R&D, sebaka se rusitseng se eketsehile hanyane nakong ea lipotoloho tsa pele tsa liteko tsa 600, mme kamora potoloho e telele ea teko, sebaka se rusitseng se ne se le maemong a mangata. Sekhahla sa tšepe se tsoetseng pele (22Cr-1.2Mo-Nb, Ti) se bonts'a hore sebaka sa mafome se nyane haholo nakong efe kapa efe ea teko.

2 Intergranular ts'enyeho hanyetsa tsa ferritic celik

410L kapa 409 celik e sebelisoa e le sesebelisoa sa taolo ea ho tsoa ha koloi ka lebaka la ho hanyetsa ha eona hantle, ho tiea le ho hanyetsa mocheso. Lilemong tsa morao tjena, mocheso oa moralo oa ho qeta koloi o eketsehile. Lebaka ke hore keketseho ea mocheso oa ho qeta koloi e ka ntlafatsa tšebetso e ntle ea bafetoleli ba motlakase le ho fokotsa likhase tse kotsi tse kang moea oa NOx, SOx le hydrocarbon (HC). Leha ho le joalo, keketseho ea mocheso e ka lebisa maemong a mabe a ho bola a thepa. Mohlala, chromium carbide e tla hlahisa li-depositi ho seretse se chesang mocheso, ke hore, mocheso oa 400 ho isa ho 500 ° C, e tla baka ho felloa ke chromium moeling oa lijo-thollo le ts'enyeho ea li-intergranular. Kaha sebaka sa weld se bohlokoa haholo ho ts'oaetso ea li-intergranular, ho hlokahala hore ho ntlafatsoe ts'ireletso ea ts'enyeho ea ts'epe e sa hloekang ea ferritic e nang le 12% Cr. Tsela e 'ngoe ea ho rarolla bothata bona ke ho etsa litšepe tse ncha tse sa hloekang tsa ferritic. Mohlala o mong ke tlatsetso ea niobium ho tšepe e nang le 12% Cr. Lisebelisoa tsena li sebelisoa ka bongata e le lisebelisoa tse sa sebetseng tsa ts'enyeho tsamaisong ea ho qeta moea, joalo ka lipeipi tse ka pele, liphaephe tse bohareng le li-muffler. Hoa tsebahala hore ho fokotsa boleng ba khabone le naetrojene ka tšepe ho sebetsa hantle haholo ho thibela ts'enyeho ea li-intergranular. Ka tsela ena, ho eketsa niobium le thaethaniamo ho tšepe ho ka ntlafatsa ntlafatso ea eona ea ts'enyeho ea li-intergranular.

3 Boemo ba tšepe e sa hloekang ea ferrite

Ts'ebeliso ea tšepe e sa hloekang ea ferritic e pharaletse haholo, 'me thepa ea tšepe e sa hloekang e hlokoang ke ts'ebeliso ka ngoe e fapane. Leha ho le joalo, sebopeho sa tšepe e sa hloekang ea ferritic se mpe ho feta sa austenitic celik joalo ka tšepe ea 304. Le ha boleng ba γ ba tšepe e sa hloekang ea ferritic, ke hore, index e tebileng ea ho hohela, e fapana ka mefuta e fapaneng ea 1.0 ho isa ho 2.0, boleng ba n, ke hore, index ea ductility e na le moeli, e ka bang 0.2, e leng tlase ho 0.4 ho 0.65 ea austenitic celik. Bakeng sa lihlahisoa tse huloang, ho thata ho sebelisa tšepe e sa hloekang ea ferritic ho nkela tšepe e sa hloekang ea austenitic. Haeba o batla ho e nkela sebaka, o tlameha ho fetola moralo oa sehlahisoa ebe o se rala ka sebopeho se huloang.

4 Thata ea ferritic celik

Liphuputso tse ngata li entsoe ka litlamorao tsa titanium le niobium ho bophahamo ba boralitaba, mme sepheo se shebiloe haholo-holo ho boleng ba karolelano. Sephetho ke hore bongata bo loketseng ba likarolo tsena bo ka ntlafatsa ntlafatso ea bophatlalatsi. Leha ho le joalo, tlatsetso e fetelletseng ea likarolo tsena le eona e ka ba le litlamorao tse mpe. Mohlala, ha likahare tsa titanium le niobium li ntse li eketseha, mocheso oa phetoho oa mapatso a longitudinal le ona oa eketseha. Le ha tšepe e sa hloekang ea ferritic e na le boleng bo botle ba gamma, mocheso oa phetoho ea ductile brittleness o ka baka tšenyo ho huleloeng ho tebileng. Kaha mocheso oa phetoho ke e 'ngoe ea lintlha tsa makhaola-khang tsa ho fetoha, ho fetoha ho ka ba thata ho tsoela pele ka mocheso o phahameng oa phetoho.

5 Matla a phahameng a mocheso oa tšepe e sa hloekang ea ferritic

Ts'epe e sa hloekang ea 409L (11Cr-Ti) e sebelisoa e le lisebelisoa tsa mekhahlelo e mengata ea ho qeta koloi, 'me mocheso oa ho qeta o etselitsoe ho ba 800 ℃. Ha mocheso oa ho qeta o ka bang 900 ° C, 430J1L (18Cr-0.4Nb-0.5Cu) ho sebelisoa tšepe e sa hloekang. Leha ho le joalo, mocheso oa ho qeta o ntse o eketseha, o hlokang ntlafatso e tsoelang pele ea boleng ba tšepe e sa hloekang. Ka tsela ena, ho hanyetsa mocheso oa tšepe e sa hloekang e phahameng ea chromium ferritic e ke ke ea fihlela litlhoko tsa mefuta e mengata ea ho qeta. Ka hona, ho 'nile ha e-ba le tlhoko e matla ea lits'ebetso tsa tlholisano e phahameng ea mocheso oa ferritic. Ha re nahana ka tlhoko ena, phello ea ho eketsa niobium le molybdenum ts'ebetsong e phahameng ea mocheso e se e ithutiloe.
