I-Super Stainless Steel kunye ne-nickel-based alloys zintlobo ezikhethekileyo zensimbi engenasici.Okokuqala, iyahluka ngokwekhemikhali kwintsimbi eqhelekileyo engenasici.Ibhekiselele kwintsimbi ephezulu ye-alloy equkethe i-nickel ephezulu, i-chromium ephezulu, i-molybdenum ephezulu.
Ngokweempawu ze-microstructure yezixhobo zensimbi engenasici, insimbi engenasici yahlulwe yaba yintsimbi ye-super ferritic, intsimbi ye-austenitic, intsimbi ye-martensitic, i-super duplex kunye nezinye iintlobo.
Super austenitic steel stainless
Ngokwesiseko sentsimbi eqhelekileyo ye-austenitic stainless steel, ngokuphucula ukucoceka kwe-alloy, ukwandisa inani lezinto ezincedo, ukunciphisa umxholo we-C, ukuthintela imvula ye-Cr23C6 ebangelwa yi-corrosion ye-intergranular, ukufumana iipropati ezilungileyo zoomatshini, iipropathi zenkqubo kunye nokuchasana kwe-corrosion yendawo. , endaweni Ti intsimbi ezinzileyo.
Super ferritic steel stainless
Izuza njengelifa iimpawu zamandla aphezulu, ukuxhathisa okulungileyo kwe-oxidation kunye noxinzelelo olubalaseleyo lokuxhathisa i-corrosion yentsimbi eqhelekileyo ye-ferritic.Kwangaxeshanye, iphucula imida yensimbi engenasici ye-ferrite kwi-welding state ye-brittle transition, enovelwano kwi-corrosion ye-intergranular kunye nokuqina okuphantsi.I-Ultra-ferritic steel stainless ene-Cr ephezulu, i-Mo kunye ne-ultra low C kunye ne-N inokufumaneka ngokucoca iteknoloji, ukunciphisa umxholo we-C kunye ne-N, ukongeza ukuzinzisa kunye ne-welding metal toughening elements.Ukusetyenziswa kwensimbi engenasici ye-ferritic kwi-corrosion resistance and chloride resistance resistance ingene kwinqanaba elitsha.
Super duplex steel stainless
Intsimbi yaphuhliswa ekupheleni kweminyaka yee-1980.Iimpawu eziphambili ziyi-SAF2507, i-UR52N, i-Zeron100, njl., ezibonakaliswe ngumxholo ophantsi we-C, umxholo we-Mo kunye nomxholo ophezulu we-N.Umxholo wesigaba se-ferritic kwi-akhawunti yensimbi ye-40% ~ 45%., enokumelana nokugqwesa okugqwesileyo.
Super martensitic steel stainless
Yintsimbi eqinileyo elukhuni enobunzima obuphezulu, amandla kunye nokumelana nokunxiba, kodwa ukuqina okungalunganga kunye nokushisela.Intsimbi eqhelekileyo ye-martensitic ayinayo i-ductility eyaneleyo, ivakalelwa kakhulu kuxinzelelo xa ikhubazekile, kwaye kunzima ukuyibumba ekusebenzeni okubandayo.Ngokunciphisa umxholo wekhabhoni kunye nokwandisa umxholo we-nickel, i-super martensitic insimbi engenasici inokufumaneka.Kwiminyaka yakutshanje, amazwe atyale imali eninzi ekuphuhliseni i-carbon ephantsi kunye ne-nitrogen ephantsi yentsimbi ye-martensitic, kwaye iphuhlise ibhetshi yentsimbi ye-martensitic ngeenjongo ezahlukeneyo.Intsimbi ye-martensitic isetyenziswe ngokubanzi kwi-oyile kunye negesi yokuxhatshazwa, ukugcinwa kunye nezixhobo zokuthutha, umbane wamanzi, ushishino lweekhemikhali, izixhobo zokuvelisa i-pulp ephezulu kunye nezinye iindawo.
Insimbi engenasici esebenzayo
Ngokutshintsha kweemfuno zemarike, iindidi zensimbi ezingenasici kunye nokusetyenziswa okukhethekileyo kunye nemisebenzi ekhethekileyo iyaqhubeka nokuvela.Okufana ne-nickel entsha ye-nickel ye-austenitic steel stainless steel entsha, i-Cr-Ni austenitic steel stainless steel, ine-biocompatibility efanelekileyo, equlethe i-Ni 13% ~ 15%.I-nickel luhlobo lwento ebangela uvakalelo, eyi-teratogenic kunye ne-carcinogenic kwizinto eziphilayo.Ukusetyenziswa ixesha elide kwe-nickel equlathe intsimbi engatyiwayo ngokuthe ngcembe itshabalalisa kwaye ikhuphe ii-Ni ion.Xa i-Ni ion ityetyiswa kwiithishu ezikufutshane nokufakelwa, iziphumo ezinobuthi zinokubangelwa kwaye iziphumo ezibi njengokutshatyalaliswa kweeseli kunye nokudumba kungenzeka.I-Cr-Mn-N yonyango ye-nickel-free austenitic steel stainless steel eyenziwe yi-Institute of Metal Research, i-Academy yaseShayina yeSayensi ivavanyelwe i-biocompatibility, kwaye ukusebenza kwayo kungcono kunoko kwe-Cr-Ni austenitic insimbi engenasici ekusebenziseni ikliniki.Omnye umzekelo yintsimbi ye-antibacterial stainless steel.Ngokuphuculwa komgangatho wokuphila kwabantu, abantu bahlawula ingqalelo ngakumbi nangakumbi kwindalo kunye nempilo yabo, ekhuthaza uphando kunye nophuhliso lwezixhobo zokulwa ne-antibacterial.Ukususela ngo-1980, amazwe aphuhlileyo amelwe yiJapan aqala ukufunda kunye nokusebenzisa izinto ezilwa ne-antibacterial kwizixhobo zasekhaya, ukupakishwa kokutya, iimfuno zemihla ngemihla, izixhobo zokuhlambela kunye nezinye iinkalo.I-Nissin Steel kunye ne-Kawasaki Steel zavelisa i-antibacterial stainless steel equlethe i-cu kunye ne-ag, ngokulandelelanayo.Intsimbi ye-antibacterial ye-Copper yongezwa kwi-stainless steel 0.5% ~ 1.0% yobhedu, emva konyango olukhethekileyo lobushushu, ukwenzela ukuba insimbi engenasici ukusuka phezulu ukuya ngaphakathi kwiyunifomu.Ukusasaza i-ε-Cu precipitates idlala indima yokulwa neentsholongwane.Olu bhedu oluqukethe i-antibacterial steel stainless steel lufanelekile kuluhlu lweemveliso ezifana ne-premium kitchenware, kunye nezinye iimveliso ezineemfuno eziphezulu zokucubungula iipropati kunye neempawu ze-antibacterial.
