Muaj ntau yam stainless hlau nyob rau hauv kev ua lag luam, tab sis thaum nws los txog rau cov zaub mov-qib stainless hlau, tsuas yog 304 stainless hlau thiab 316 stainless hlau tuaj rau hauv lub siab, yog li dab tsi yog qhov txawv ntawm ob? Thiab yuav xaiv nws li cas? Hauv qhov teeb meem no, peb yuav qhia lawv grandly.
Qhov txawv:
Ua ntej tshaj plaws, cia peb tham txog lawv qhov sib txawv, peb yuav tsum pib nrog cov ntsiab lus ntawm txhua yam hlau hauv lawv. Lub teb chaws tus qauv qib ntawm 304 stainless hlau yog 06Cr19Ni10, thiab lub teb chaws tus qauv qib ntawm 316 stainless hlau yog 0Cr17Ni12Mo2. Nickel (Ni) cov ntsiab lus ntawm 304 stainless hlau yog 8% -11%, npib tsib xee (Ni) cov ntsiab lus ntawm 316 stainless hlau yog 10% -14%, thiab nickel (Ni) cov ntsiab lus ntawm 316 stainless hlau yog (Ni) cov ntsiab lus nce. Raws li peb txhua tus paub, lub luag haujlwm tseem ceeb ntawm cov khoom siv nickel (Ni) hauv cov khoom siv hlau yog los txhim kho corrosion kuj, oxidation tsis kam, txhua yam khoom thiab kub tsis kam ntawm stainless hlau. Yog li ntawd, 316 stainless hlau yog superior rau 304 stainless hlau nyob rau hauv no yam.
Qhov thib ob yog tias 316 stainless hlau ntxiv 2% -3% molybdenum (Mo) lub hauv paus ntawm 304 stainless hlau. Kev ua haujlwm ntawm molybdenum (Mo) lub caij yog txhawm rau txhim kho hardness ntawm stainless hlau, nrog rau kev txhim kho qhov kub thiab txias thiab corrosion kuj ntawm stainless hlau. . Qhov no tau txhim kho kev ua tau zoo ntawm 316 stainless hlau hauv txhua yam, uas yog vim li cas 316 stainless hlau kim dua 304 stainless hlau.
Raws li peb txhua tus paub, 304 stainless hlau yog cov khoom siv stainless hlau dav dav, thiab nws tseem yog cov hlau tsis zoo tshaj plaws hauv lub neej niaj hnub, xws li stainless hlau tableware, thermos khob, thiab ntau yam khoom siv txhua hnub. Haum rau kev lag luam siv nyob rau hauv ib txwm ambient tej yam kev mob thiab siv rau machinery. Txawm li cas los xij, kev tiv thaiv corrosion thiab ntau yam khoom ntawm 316 stainless hlau yog ntau dua li ntawm 304 stainless hlau, yog li daim ntawv thov ntau yam ntawm 316 stainless hlau yog qhov dav. Thawj yog nyob rau hauv cov ntug dej hiav txwv thiab kev lag luam shipbuilding, vim hais tias cov huab cua nyob rau hauv lub ntug dej hiav txwv yog ib tug kuj humid thiab yooj yim rau corrode, thiab 316 stainless hlau muaj corrosion kuj ntau dua 304 stainless hlau; Qhov thib ob yog cov khoom siv kho mob, xws li scalpels, vim tias 304 stainless hlau yog cov zaub mov qib stainless hlau, 316 stainless hlau tuaj yeem ncav cuag qib kho mob; qhov thib peb yog cov tshuaj lom neeg kev lag luam uas muaj zog acid thiab alkali; qhov thib plaub yog kev lag luam uas yuav tsum tau ua haujlwm nyob rau hauv qhov kub thiab txias.
Raws li qhov tshwm sim, 316 stainless hlau yog ib yam khoom uas tuaj yeem hloov 304 stainless hlau nyob rau hauv ntau yam hnyav.
