Kugereranya imikorere ya 304L na 316L yogejwe Icyuma

304 na 316 byombi ni code yicyuma kitagira umwanda.Muri rusange, ntaho batandukaniye.Byombi ni ibyuma bidafite ingese, ariko ni ubwoko butandukanye iyo bigabanijwe.Ubwiza bwibyuma 316 bidafite ingese biruta ubw'ibyuma 304 bidafite ingese.Hashingiwe kuri 304,316 ibyumaikubiyemo icyuma cya molybdenum, gishobora kurushaho gushimangira imiterere ya molekile yicyuma.Kora cyane birwanya kwambara no kurwanya okiside, kandi mugihe kimwe, kurwanya ruswa nabyo byiyongera cyane
Kugereranya imikorere ya 304L na316L yogeje Icyuma
Kurwanya kwangirika kwibyuma bidafite ingese bifite agaciro kanini kuruta kwihanganira ikizinga.Nkumuti, icyambere cyicyuma kitagira ingese nicyuma, ariko kubera kongeramo ibindi bintu, birashobora kugera kubintu byinshi byifuzwa.Chromium nikintu kigena ibyuma bidafite ingese, byibuze 10.5% yibigize.Ibindi bintu bivangavanze birimo nikel, titanium, umuringa, azote na selenium.
Itandukaniro riri hagati ya 304L na 316L yogejwe Icyuma kitagira umuyonga niho habaho chromium, 316L yogejwe ibyuma bitagira umuyonga bifite imbaraga zo kurwanya ruswa, cyane cyane mubidukikije biciriritse hamwe n’umunyu mwinshi.Kubisabwa hamwe nibikoresho byo hanze bidafite ibyuma, ibyuma bidafite ingese nibintu byiza birwanya ruswa kubirebire igihe kirekire hanze.
Kurwanya ruswa
Ibintu bitandukanye bya chromium nibindi bintu birashobora kwerekana impamyabumenyi zitandukanye zo kurwanya ruswa.Ibyiciro bibiri bikunze kugaragara cyane ni 304 na 316. Ruswa nikintu gisanzwe, nkuko icyuma gikora muburyo busanzwe hamwe nibidukikije.Mubyukuri, ibintu bike cyane bishobora kugaragara muburyo bwiza - zahabu, ifeza, umuringa, na platine ni ingero nke cyane.
Chromium oxyde ikora firime ikingira imbere
Ingese ni inzira ya molekile y'icyuma ihuza na ogisijeni muri molekile y'amazi, kandi igisubizo ni ikizinga gitukura gikunda kuba kibi - cyangiza ibintu byinshi.Muri ibyo, ibyuma na karubone byoroshye cyane kwangirika.
Ibyuma bidafite ingese bifite ubushobozi busanzwe bwo kwangirika hejuru, ibi biva gute?Chromium mubyuma byose bidafite umwanda byihuta cyane muri ogisijeni, nkicyuma.Itandukaniro nuko urwego ruto rwa chromium ruzaba rufite okiside (mubisanzwe molekile nkeya mububyimbye).Ntabwo bitangaje, iki gice cyoroshye cyo kurinda kiraramba cyane.
304L yogejwe ibyuma bitagira umuyonga bifite isura nziza nigiciro gito cyo kubungabunga.304L yogejwe ibyuma bitagira umuyonga ntibishobora kuba ingese, kubwibyo ikoreshwa kenshi mubikoresho byo guteka no gukoresha ibiryo.Ariko irashobora kwanduzwa na chloride (mubisanzwe ahantu h'umunyu mwinshi).Chloride ikora ubwoko bwa ruswa ishobora kwitwa "ikibanza cyangirika" kigera mumiterere yimbere.
304 ibyuma bidafite ingese nicyuma gikoreshwa cyane mubyuma.Irimo chromium 16% -24% na nikel igera kuri 35% - hamwe na karubone na manganese.Uburyo bukunze kugaragara 304 ibyuma bitagira umuyonga ni 18-8, cyangwa 18/8 ibyuma bitagira umwanda, bivuze chromium 18% na nikel 8%.
316 ibyuma bitagira umwanda nabyo bikoreshwa cyane mubyuma.Imiterere yumubiri nubukanishi bisa na 304 ibyuma bidafite ingese.Itandukaniro nuko ibyuma 316 bidafite ingese birimo 2-3% molybdenum, byongera imbaraga no kurwanya ruswa.Mubisanzwe 300 serie idafite ibyuma irashobora kuba irimo aluminium igera kuri 7%.
304L na 316Lguswera ibyuma(kimwe nizindi 300 zikurikirana zitagira ibyuma) koresha nikel kugirango ugumane ubwiza bwubushyuhe buke.
