Kunomehluko omkhulu phakathi kwe-duplex steel stainless steel mesh 2205 kanye no-2207 ezicini eziningi. Okulandelayo ukuhlaziya okuningiliziwe nesifinyezo somehluko wabo:
Ukwakheka kwamakhemikhali nokuqukethwe kwe-elementi:
2205 duplex insimbi engagqwali: ikakhulukazi eyakhiwe ngo-21% we-chromium, u-2.5% we-molybdenum kanye no-4.5% we-nickel-nitrogen alloy. Ngaphezu kwalokho, iqukethe inani elithile le-nitrogen (0.14 ~ 0.20%), kanye nenani elincane lezakhi ezifana nekhabhoni, i-manganese, i-silicon, i-phosphorus nesulfure.
2207 Duplex Stainless Steel (eyaziwa nangokuthi F53): Futhi iqukethe u-21% we-chromium, kodwa inokuqukethwe okuphezulu kwe-molybdenum ne-nickel kuno-2205. Okuqukethwe okuthile kungase kuhluke kancane ngenxa yamazinga ahlukene noma abakhiqizi, kodwa ngokuvamile okuqukethwe kwe-molybdenum kuphezulu futhi okuqukethwe kwe-nickel nakho kuphezulu uma kuqhathaniswa.
Izici zokusebenza:
2205 duplex insimbi engagqwali:
Inamandla aphezulu kanye nokuqina komthelela omuhle.
Inokumelana okuhle kwendawo yonke kanye nokugqwala kwengcindezi.
Ngenxa yokuqukethwe okuphezulu kwe-chromium, i-molybdenum ne-nitrogen ekubunjweni kwayo kwamakhemikhali, inokulingana nokugqwala okuphezulu kwe-anti-pitting (inani le-PREN 33-34). Cishe kuyo yonke imidiya egqwalayo, ukumelana nokugqwala kwe-pitting kanye nokumelana nokugqwala kwe-crevice kungcono kune-316L Noma 317L insimbi engagqwali ye-austenitic.
2207 duplex insimbi engagqwali:
Inokumelana nokugqwala okungcono futhi imelana nokugqoka, ikakhulukazi ngokumelene nemithombo yezindaba ebolayo njengama-asidi aqinile, ama-alkali nama-ion e-chloride.
Inamandla aphakeme nobulukhuni futhi ihlala isikhathi eside kunensimbi evamile engagqwali.
Ine-plasticity enhle nokucutshungulwa, kanye nokuqina okuhle kakhulu nokumelana nokukhathala.
Izindawo zokufaka isicelo:
2205 duplex insimbi engagqwali: esetshenziswa kabanzi embonini yamakhemikhali, imboni kawoyela negesi, ubunjiniyela basolwandle, imboni yezokwakha, imboni ye-aerospace kanye neminye imikhakha. Ukumelana nokugqwala kwayo okuhle kakhulu kuyenza ibe inketho ekahle yokwenziwa kwemikhumbi, amapulatifomu asogwini nezinye izinto zokusebenza.
2207 duplex insimbi engagqwali: futhi ilungele izindawo ezigqwala kakhulu, ikakhulukazi ezindaweni ezinokhahlo njengobunjiniyela basolwandle kanye nemboni yamakhemikhali. Ngenxa yezici zayo ezihlukile zokusebenza, ibuye isetshenziswe kabanzi emikhakheni efana nokumba uwoyela negesi.
Ukusebenza kwe-welding kanye nezindleko:
I-2205 duplex insimbi engagqwali inokushisela okuhle. Akudingi ukushisa kwangaphambili ngesikhathi sokushisela noma ukwelashwa kokushisa ngemva kokushisela, okwenza inqubo yokushisela ibe lula.
Ngokuphambene, ukusebenza kokushisela kwe-2207 duplex stainless steel kubi kakhulu futhi kudinga izinqubo zokushisela ezikhethekile. Ngaphezu kwalokho, ngenxa yokusebenza kwayo okuhle kakhulu, intengo ye-2207 duplex steel stainless iphakeme uma kuqhathaniswa nezindleko zokukhiqiza ziphezulu.
