Izinsimbi ezingagqwali ezi-Duplex, ezidume ngokuhlanganiswa kwazo kwezimpawu ze-austenitic kanye ne-ferritic, zimi njengobufakazi bokuvela kwe-metallurgy, zinikeza i-synergy yezinzuzo ngenkathi zinciphisa izithiyo ezingokwemvelo, ngokuvamile endaweni yentengo yokuncintisana.
Ukuqonda i-Duplex Stainless Steel:
Okubalulekile engqikithini yensimbi engagqwali eyi-duplex ukwakheka kwayo kwezigaba ezimbili, okuvamise ukuhlanganisa inhlanganisela elinganayo ye-austenite ne-ferrite, edala i-symbiosis yezici ezivumayo kuyilapho kunciphisa ubungozi. Ukwakheka kwe-metallurgical, nakuba kuncike ebangeni elithile, kuvame ukuhlanganisa ikhabhoni, i-manganese, i-silicon, i-chromium, i-nickel, i-phosphorus, nesibabule, ezinezithasiselo ongazikhethela njenge-molybdenum, i-nitrogen, nethusi okuqhubeka nokucwenga izakhiwo zezinto.
Umongo Womlando Wensimbi Engagqwali ye-Duplex:
I-genesis ye-duplex stainless alloys ilandelela emuva emiculweni yethiyori ngeminyaka yawo-1920s, efinyelela umvuthwandaba ngebhizinisi lokukhiqiza elibambekayo ngeminyaka yawo-1930s. Ekuqaleni ivalelekile ekukhiqizeni ukusakaza nezinhlelo zokusebenza ezikhethekile ngenxa yokuqukethwe kwekhabhoni ephakeme, intuthuko ekususweni kwe-carbur ngasekupheleni kwawo-1960 yamemezela inkathi entsha, yenza kube lula ukuhlanganiswa kwengxube ye-carbon ephansi enokuqukethwe kwe-chromium ne-nickel ethuthukisiwe, ngaleyo ndlela kucwengisiswe ibhalansi phakathi kwe-ferrite ne-austenite. Okuwuphawu lwalo mzila wokuziphendukela kwemvelo i-Duplex 2205, ingxubevange yamaphayona kusukela maphakathi nawo-1970s esaqhubeka nokubamba ukuhlobana ngenxa yokumelana kwayo okuphakeme nokugqwala okuhambisana namamaki avamile e-austenitic.
Izinzuzo ze-Duplex Stainless Steel:
Ngaphandle kokwakha ingxenye encane yemakethe yensimbi engagqwali, ama-alloys ayi-duplex akhiqiza i-spectrum yokufaneleka ngokuqhathaniswa nozakwabo bendabuko be-austenitic kanye ne-ferritic. Okuphawulekayo phakathi kwalezi zinzuzo amandla aphakeme, ukuqina okungeziwe, kanye ne-ductility, nokumelana nokugqwala okuvela njengesici esiphawulekayo, ukuncintisana, uma kungedluli, lokho kwamamaki e-austenitic. Ngaphezu kwalokho, ukuphumelela kwezindleko okutholakala ku-duplex steel, ngenxa yokuqashwa okuhlakaniphile kwezinto ezihlanganisiwe, kuyenza ibe ukukhetha okuphoqelela kuzo zonke izinhlelo zokusebenza ezihlukahlukene.
Ukusetshenziswa kwe-Duplex Stainless Steel:
Ukuguquguquka kwensimbi engagqwali e-duplex kuthola ukuzwakala kuzo zonke izimboni nezizinda, ngenxa yokumelana nokugqwala kwe-stellar, amandla athuthukisiwe, kanye nezibaluli eziyongayo. Ikakhulukazi, ukusebenza kwe-offshore and near-shore, okuhlanganisa ukumba uwoyela, ukukhishwa kukasawoti emanzini, nokuhlanza amanzi, kuba ngabazuzi abakhulu bobungcweti be-duplex steel. Ngokufanayo, ukusetshenziswa kwayo kudlulela ekucutshungulweni kwamakhemikhali, ukusetshenziswa kwemikhumbi, izinto zokulawula ukungcoliswa komhlaba, kanye nemizamo yokwakha, kugcizelela ukuba khona kwayo yonke indawo ezindaweni zezimboni zesimanje.
