Intshayelelo kwi Duplex Stainless Steel

Iintsimbi ezingenazintsimbi eziDuplex, ezidume ngokudityaniswa kweempawu ze-austenitic kunye ne-ferritic, zime njengobungqina bokuvela kwesinyithi, zibonelela ngolungelelwaniso lweenzuzo ngelixa zithomalalisa iingxaki zendalo, rhoqo kwinqanaba lokhuphiswano.

Ukuqonda i-Duplex Stainless Steel:

Okusembindini kundoqo we-duplex yentsimbi engatyiwayo sisigaba se-microstructure sayo esinezigaba ezimbini, esiquka umdibaniso olungeleleneyo we-austenite kunye ne-ferrite, evelisa i-symbiosis yeempawu ezithandekayo ngelixa inciphisa ubuthathaka. Ukwakhiwa kwe-metallurgical, nangona kuxhomekeke kwibakala elithile, lihlala libandakanya i-carbon, i-manganese, i-silicon, i-chromium, i-nickel, i-phosphorus, kunye nesulfure, kunye nezongezo ezikhethiweyo ezifana ne-molybdenum, i-nitrogen, kunye nobhedu oluphucula ngakumbi iipropathi zezinto.

Umxholo wezeMbali weDuplex Steel:

I-genesis ye-duplex stainless alloys ibuyela emva kwi-musings yethiyori ngo-1920s, ifikelela kuvuthondaba lwemveliso ebonakalayo ngexesha le-1930s. Ekuqaleni bekuvalelwe imveliso ephosiweyo kunye nezicelo ezikhethekileyo ngenxa yokunyuswa kwekhabhoni, ukuqhubela phambili kwi-decarburization ngasekupheleni kweminyaka yoo-1960 kubhengeze ixesha elitsha, kuququzelela ukuhlanganiswa kweealloyi zekhabhoni ephantsi kunye nomxholo we-chromium kunye ne-nickel, ngaloo ndlela kusulungekiswa ibhalansi phakathi kwe-ferrite kunye ne-austenite. Umfuziselo wale trajectory yendaleko yi-Duplex 2205, ialloyi yobuvulindlela ukusuka kwiminyaka yoo-1970s eqhubeka iyalela ukubaluleka ngenxa yokumelana kwayo nokudleka okugqwesileyo ngokuhambelana namabakala aqhelekileyo e-austenitic.

Izinto eziluncedo kwiDuplex Stainless Steel:

Ngaphandle kokwenza iqhezu elincinane kwimakethi yentsimbi engatyiwayo, iialloyi eziphindwe kabini zibonelela ngoluhlu lwezinto ezincomekayo xa kuthelekiswa nezakwantu ze austenitic kunye neferritic. Okuphawulekayo phakathi kwezi zibonelelo kukomelela okongeziweyo, ukuqina okwandisiweyo, kunye ne-ductility, kunye nokumelana nokubola okuvelayo njengophawu oluphawulwayo, ukukhuphisana, ukuba alugqithisi, lwamabanga e-austenitic. Ngaphezu koko, ukusebenza kakuhle kwexabiso kwi-duplex steel, ngenxa yokuqeshwa ngobuchule kwezinto ezixutyiweyo, kuyenza ibe lukhetho olunyanzelisayo kuzo zonke iintlobo zezicelo.

Usetyenziso lwe-Duplex Stainless Steel:

Ukuguquguquka kwentsimbi ephindwe kabini ifumana iresonance kuwo wonke uluhlu lwemizi-mveliso kunye nemimandla, ngenxa yokuxhathisa kwayo kwi-stellar corrosion, ukomeleza ukomelela, kunye neempawu zokonga imali. Ikakhulu, imisebenzi ekude nonxweme nakufutshane nonxweme, equka ukombiwa kwe-oyile, ukukhutshwa kwetyuwa emanzini, kunye nokucocwa kwamanzi, kume njengabaxhamli abaphambili bobuchule be-duplex steel. Ngokufanayo, usetyenziso lwayo lunabela ekusetyenzweni kweekhemikhali, usetyenziso lwaselwandle, izixhobo zolawulo longcoliseko, kunye nemizamo yokwakha, igxininisa ukubakho kwayo kwindawo yonke yemizi-mveliso yangoku.
