Vim li cas duplex stainless hlau thiaj li kim?
Vim li cas duplex stainless hlau thiaj li kim?
Yog vim li cas vim li cas duplex stainless hlau kim tuaj yeem piav qhia los ntawm cov hauv qab no:
Tus nqi ntawm cov khoom siv: Duplex stainless hlau muaj cov feem ntau ntawm cov alloying ntsiab nyob rau hauv nws muaj pes tsawg leeg, xws li chromium, molybdenum thiab nickel. Cov ntsiab lus no lawv tus kheej muaj cov nqi lag luam siab thiab raug nqi ntau hauv cov txheej txheem refining thiab synthesis, uas cuam tshuam ncaj qha rau cov khoom siv ntawm duplex stainless hlau. Cov txheej txheem ntau lawm: Kev tsim cov duplex stainless hlau suav nrog cov txheej txheem nyuaj xws li forging, txias dov thiab tom qab annealing. Cov kauj ruam no yuav tsum muaj kev siv thev naus laus zis siab thiab kev ua haujlwm siab, ua rau kom muaj kev nyuaj thiab nyuaj ntawm kev tsim khoom, ua rau cov nqi ntau dua. Kev lag luam xav tau: Nrog rau kev txhim kho kev lag luam, tshwj xeeb tshaj yog qhov kev thov loj hlob rau cov khoom siv corrosion-resistant, cov khoom siv ntawm duplex stainless hlau tau ntsib kev loj hlob sai. Kev nthuav dav ntawm kev ua lag luam kuj tau txhawb nqa kev kawm txuj ci, tab sis nws kuj tau ua rau cov khoom siv raw khoom nruj, txuas ntxiv thawb tus nqi. Kev ua tau zoo: Duplex stainless hlau muaj cov khoom siv zoo heev thiab kev tiv thaiv corrosion, thiab nws lub zog tawm los yog siab dua li cov hlau tsis zoo tib yam, uas txhais tau hais tias cov ntaub ntawv tuaj yeem txuag tau thiab tag nrho cov khoom tsim khoom raug txo qis hauv tib yam kev siv. Qhov kev ua tau zoo no ua rau nws hloov tsis tau hauv qee qhov chaw tshwj xeeb, yog li tus nqi kuj tseem siab.
