Super Stainless Steel ma nickel-based alloys o ituaiga faʻapitoa o uʻamea uʻamea.Muamua, e ese mai kemikolo mai uamea stainless masani.E fa'atatau i u'amea u'amea maualuga o lo'o i ai nikeli maualuga, chromium maualuga, molybdenum maualuga.
E tusa ai ma le microstructure uiga o mea uʻamea uʻamea, ua vaevaeina super uʻamea uʻamea uʻamea uʻamea, super austenitic uʻamea uʻamea, super martensitic uamea stainless, super duplex uamea stainless ma isi ituaiga.
Super austenitic uamea uamea
I luga o le faʻavae o le austenitic stainless steel masani, e ala i le faʻaleleia o le mama o le uʻamea, faʻateleina le numera o elemene aoga, faʻaitiitia le anotusi o le C, puipuia le faʻafefe o le Cr23C6 e mafua mai i le intergranular corrosion, maua ni mea faʻainisinia lelei, faʻagasologa o meatotino ma le faʻaleagaina o le lotoifale. , sui Ti u'amea maumea stainless.
Super ferritic uamea uamea
E maua ai le uiga o le malosi maualuga, oxidation tetee lelei ma sili atu le popole corrosion tetee o ferritic masani uamea.I le taimi lava e tasi, e faʻaleleia ai tapulaʻa o le ferrite stainless steel i le tulaga uelo o suiga brittle, maaleale i intergranular corrosion ma maualalo toughness.Ultra-ferritic stainless steel ma maualuga Cr, Mo ma ultra low C ma N e mafai ona maua e ala i le faamamaina o tekinolosi, faʻaitiitia le anotusi o le C ma le N, faʻaopoopo le faʻamautuina ma le uʻamea elemene toughening uʻamea.O le faʻaogaina o le uʻamea uʻamea ferritic i le faʻafefeteina ma le chloride teteʻe faʻamaʻi ua ulufale atu i se tulaga fou.
Super duplex uamea uamea
O le uamea na fausia i le faaiuga o le 1980s.O faʻailoga autu o SAF2507, UR52N, Zeron100, ma isi, o loʻo faʻaalia i le maualalo o le C content, maualuga le Mo ma le maualuga o le N.O le ferritic vaega o loʻo i totonu o le uʻamea e maua ai le 40% ~ 45%., fa'atasi ai ma le fa'afefeteina lelei.
Super martensitic uamea uamea
O se uamea stainless hardenable ma le maaa maualuga, malosi ma le ofuina tete'e, ae le lelei toughness ma weldability.Ordinary martensitic stainless steel le lava ductility, e matua maaleale i le popole pe a deformed, ma e faigata ona fausia i le galuega malulu.E ala i le faʻaitiitia o le carbon content ma faʻateleina le nickel content, e mafai ona maua le super martensitic stainless steel.I tausaga talu ai nei, ua faʻapipiʻiina e atunuu le tele o tupe i le atinaʻeina o le carbon low ma le maualalo o le nitrogen super martensitic steel, ma atiina ae se vaega o super martensitic sila mo faamoemoega eseese.Super martensitic uʻamea ua faʻaaogaina lautele i le suauʻu ma le kesi faʻaogaina, teuina ma felauaiga meafaigaluega, hydropower, alamanuia vailaʻau, vevela maualuga masini gaosiga masini ma isi fanua.
u'amea u'amea aoga
Faatasi ai ma le suiga o manaoga maketi, o loʻo faʻaauau pea ona faʻaalia le tele o uʻamea uʻamea faʻatasi ai ma faʻaoga faʻapitoa ma galuega faʻapitoa.E pei o le nickel faafoma'i fou austenitic mea uamea u'amea u'amea e tele lava Cr-Ni austenitic u'amea u'amea, ei ai biocompatibility lelei, e aofia ai Ni 13% ~ 15%.O le nikeli o se ituaiga o mea e fa'amanino, e teratogenic ma fa'ama'i i meaola.O le fa'aumiumi o le fa'aogaina o le nickel-containing stainless steel e faasolosolo malie lava ona fa'aumatia ma fa'asa'oloto ai Ni ions.A fa'atamaoaigaina ni ion i totonu o masini e latalata i le totoina, o a'afiaga oona e mafai ona fa'aosofia ma fa'alavelave leaga e pei o le fa'aleagaina o sela ma le mumū e mafai ona tupu.Cr-Mn-N faafomai nickel-free austenitic stainless uamea atiina ae e Inisetiute o Metal Research, Saina Academy o Saienisi ua tofotofoina mo biocompatibility, ma o lona faatinoga e sili atu nai lo le Cr-Ni austenitic uamea stainless i le faaaogaina falemai.O le isi faʻataʻitaʻiga o le antibacterial stainless steel.Faʻatasi ai ma le faʻaleleia atili o le tulaga o le soifuaga o tagata, e sili atu le gauai atu o tagata i le siosiomaga ma o latou lava soifua maloloina, lea e faʻamalosia ai le suʻesuʻeina ma le atinaʻeina o mea faʻamaʻi.Talu mai le 1980, o atunuʻu atinaʻe o loʻo faʻatusalia e Iapani na amata suʻesuʻe ma faʻaaogaina mea faʻamaʻi i totonu o meafale, afifiina o meaʻai, mea e manaʻomia i aso uma, mea taʻele ma isi vaega.Na fausia e Nissin Steel ma Kawasaki Steel le u'amea antibacterial e iai le cu ma le ag.Kopa antibacterial uamea stainless ua faaopoopo i uʻamea uʻamea 0.5% ~ 1.0% apamemea, ina ua uma togafitiga vevela faapitoa, ina ia le uamea stainless mai luga i totonu o le toniga.Ta'ape ε-Cu precipitates e faia se vaega antibacterial.O lenei kopa o loʻo i ai le antibacterial stainless steel e talafeagai mo le tele o oloa e pei o le umukuka faʻapitoa, faʻapea foʻi ma isi oloa e manaʻomia maualuga mo le gaosiga o meatotino ma mea faʻamaʻi.
