I-Super Stainless Steel kanye nama-alloys asekelwe ku-nickel yizinhlobo ezikhethekile zensimbi engagqwali.Okokuqala, ihluke ngamakhemikhali ensimbi engagqwali evamile.Isho insimbi engagqwali ephezulu equkethe i-nickel ephezulu, i-chromium ephezulu, i-molybdenum ephezulu.
Ngokwezici ze-microstructure yezinto zensimbi engagqwali, insimbi engagqwali enkulu ihlukaniswe yaba insimbi engagqwali ye-super ferritic, i-super austenitic stainless steel, i-super martensitic stainless steel, i-super duplex insimbi engagqwali nezinye izinhlobo.
Super austenitic insimbi engagqwali
Ngokwesisekelo sensimbi engagqwali evamile ye-austenitic, ngokwenza ngcono ubumsulwa be-alloy, ukwandisa inani lezinto eziwusizo, ukunciphisa okuqukethwe kwe-C, ukuvimbela imvula ye-Cr23C6 ebangelwa ukugqwala kwe-intergranular, thola izakhiwo ezinhle zemishini, izakhiwo zenqubo kanye nokumelana nokugqwala kwendawo. , esikhundleni se-Ti stable stainless steel.
Super Ferritic insimbi engagqwali
Izuza njengefa izici zamandla aphezulu, ukumelana okuhle kwe-oxidation nokumelana okuhle kakhulu nokugqwala kwengcindezi yensimbi engagqwali ye-ferritic evamile.Ngesikhathi esifanayo, ithuthukisa ukulinganiselwa kwensimbi engagqwali ye-ferrite esimweni sokushisela se-brittle transition, ezwela ukugqwala kwe-intergranular kanye nokuqina okuphansi.Insimbi engagqwali ye-Ultra-ferritic ene-Cr ephezulu, i-Mo ne-ultra low C no-N ingatholwa ngobuchwepheshe bokucwenga, ngokunciphisa okuqukethwe kuka-C no-N, okwengeza izinto eziqinisayo nezishisela insimbi.Ukusetshenziswa kwensimbi engagqwali ye-ferritic ekumelaneni nokugqwala kanye nokumelana nokugqwala kwe-chloride kungene esigabeni esisha.
Super duplex insimbi engagqwali
Insimbi yasungulwa ngasekupheleni kwawo-1980.Izinhlobo eziyinhloko yi-SAF2507, UR52N, Zeron100, njll., ezibonakala ngokuqukethwe okuphansi kwe-C, okuqukethwe kwe-Mo okuphezulu nokuqukethwe okuphezulu kwe-N.Okuqukethwe kwesigaba se-ferritic kuma-akhawunti ensimbi angama-40% ~ 45%., enokumelana nokugqwala okuhle kakhulu.
Super martensitic insimbi engagqwali
Kuyinsimbi engagqwali eqinile enobulukhuni obuphezulu, amandla nokumelana nokugqoka, kodwa ukuqina okungenamandla kanye nokushisela.Insimbi engagqwali evamile ye-martensitic ayinakho ukudumba okwanele, izwela kakhulu ekucindezelekeni lapho ikhubazekile, futhi kunzima ukuyakheka ekusebenzeni okubandayo.Ngokunciphisa okuqukethwe kwekhabhoni nokwandisa okuqukethwe kwe-nickel, i-super martensitic insimbi engagqwali ingatholakala.Eminyakeni yamuva nje, amazwe atshale imali eningi ekuthuthukiseni ikhabhoni ephansi kanye nensimbi ephansi ye-nitrogen super martensitic, futhi athuthukisa inqwaba yensimbi ye-super martensitic ngezinhloso ezahlukene.Insimbi ye-Super martensitic isetshenziswe kabanzi ekuxhashazweni kukawoyela negesi, ukugcinwa kwezinto zokuhamba nezokuthutha, ugesi wamanzi, imboni yamakhemikhali, imishini yokukhiqiza i-pulp ephezulu yokushisa kanye neminye imikhakha.
Insimbi engagqwali esebenzayo
Ngokushintsha kwesidingo semakethe, izinhlobonhlobo zensimbi engagqwali ezisebenzisa ngokukhethekile kanye nemisebenzi ekhethekile iyaqhubeka nokuvela.Okufana nensimbi entsha ye-nickel yezokwelapha yamahhala ye-austenitic yensimbi engagqwali ngokuyinhloko i-Cr-Ni austenitic insimbi engagqwali, inokusebenzisana okuhle kwe-biocompatibility, equkethe i-Ni 13% ~ 15%.I-Nickel iwuhlobo lwesici esizwelayo, esiyi-teratogenic kanye ne-carcinogenic ephilayo.Ukusetshenziswa isikhathi eside kwensimbi egxiliwe ene-nickel equkethe insimbi engagqwali kancane kancane kucekele phansi futhi kukhiphe ama-Ni ions.Lapho ama-Ni ions ehlanganiswa ezicutshini eduze nokufakelwa, imiphumela enobuthi ingadaleka futhi kube nokusabela okubi njengokubhujiswa kwamangqamuzana nokuvuvukala kungenzeka.I-Cr-Mn-N yensimbi ye-austenitic engagqwali ye-nickel yezokwelapha engena-nickel eyakhiwe yi-Institute of Metal Research, i-Chinese Academy of Sciences ihlolelwe ukuhambisana ne-biocompatibility, futhi ukusebenza kwayo kungcono kunaleyo ye-Cr-Ni austenitic stainless steel ekusetshenzisweni komtholampilo.Esinye isibonelo insimbi engagqwali elwa namagciwane.Ngokuthuthukiswa kwezinga lokuphila kwabantu, abantu banaka kakhulu imvelo kanye nempilo yabo, okukhuthaza ucwaningo nokuthuthukiswa kwezinto ezilwa namagciwane.Kusukela ngo-1980, amazwe athuthukile amelwe yiJapane aqala ukufunda nokusebenzisa izinto ezilwa namagciwane ezintweni zasendlini, ukupakisha ukudla, izidingo zansuku zonke, izinto zokugeza nezinye izici.I-Nissin Steel ne-Kawasaki Steel zakha insimbi engagqwali elwa namagciwane equkethe i-cu ne-ag, ngokulandelana.Insimbi engagqwali ye-Copper yengezwe ensimbi engagqwali 0.5% ~ 1.0% yethusi, ngemuva kokwelashwa okukhethekile kokushisa, ukuze insimbi engagqwali isuka phezulu iye ngaphakathi komfaniswano.Ukuhlakaza i-ε-Cu precipitate kudlala indima yokulwa namagciwane.Le khopha equkethe insimbi engagqwali elwa namagciwane ifanele uhla lwemikhiqizo efana ne-premium kitchenware, kanye neminye imikhiqizo enezidingo eziphezulu zokucubungula izakhiwo kanye nezindawo zokulwa namagciwane.
