Aisi 430 stainless hlau vs stainless hlau 304
Aisi 430 stainless hlau vs stainless hlau 304
AISI 430 yog cov hlau nplaum, tus nqi - zoo ferritic stainless hlau nrog zoo formability; thaum AISI 304 (qib feem ntau) tsis yog -sib nqus, muaj kev tiv thaiv corrosion zoo thiab zoo dua, thiab tsim nyog rau vuam vim nws cov ntsiab lus ntau dua nickel. Yog li, 304 stainless hlau zoo dua rau qhov chaw hnyav, thaum 430 stainless hlau yog qhov zoo tagnrho rau tus nqi- cov ntawv thov sab hauv tsev xav tau qhov zoo nkauj zoo nkauj (xws li cov khoom siv hauv tsev lossis cov khoom dai).
Dab tsi yog kev siv 430 stainless hlau?
430 stainless hlau muaj cov ntsiab lus tsis tshua muaj npib tsib xee, kwv yees li 0.75% (qhov siab tshaj), ua rau nws siv nyiaj ntau dua li austenitic stainless hlau . 430 stainless hlau yog feem ntau siv rau hauv cov ntawv thov uas yuav tsum tau muaj kev tiv thaiv corrosion, xws li cov khoom siv hauv chav ua noj, tsheb txiav, architectural hniav ntsiab, thiab cov khoom siv.
Dab tsi yog 304 stainless hlau?
304 stainless hlau yog chromium -nickel alloy uas muaj corrosion kuj zoo heev. Yog li ntawd, nws yog ib qho kev xaiv zoo tshaj plaws rau cov ntawv thov uas xav tau kev ua haujlwm siab thiab xeb tsis kam.
Tsis tas li ntawd, 304 stainless hlau yog yooj yim dua rau kev tsim thiab txheej txheem piv rau ntau lwm hom stainless hlau, ua rau nws nyiam cov khoom siv rau tej yaam num uas yuav tsum tau high precision los yog complex cov ntsiab lus.
Dab tsi yog 430 stainless hlau?
430 stainless hlau yog ib hom stainless hlau paub txog nws cov corrosion kuj thiab tsis tshua muaj kev ua xua. Nws kuj muaj qhov muaj zog tiv thaiv ib puag ncig hnyav thiab tshuaj lom neeg corrosion, ua rau nws haum rau ntau yam kev siv.
Vim nws muaj peev xwm tiv taus qhov kub thiab txias ib puag ncig, 430 stainless hlau feem ntau yog siv rau hauv ntim khoom noj thiab khoom siv kho mob.

430 Stainless hlau vs . 304 Stainless hlau
Tus nqi:Tus nqi ntawm stainless hlau feem ntau yog nyob ntawm tus nqi ntawm nws cov ntsiab lus, uas hloov pauv hauv lub ntiaj teb kev ua lag luam . 304 stainless hlau feem ntau kim dua 430 stainless hlau vim tias nws muaj 8-10.5% npib tsib xee, ib qho khoom kim heev uas txhim kho corrosion tiv thaiv. 430 stainless hlau tsis muaj npib tsib xee, ua rau nws pheej yig dua.
Magnetism:304 stainless hlau yog austenitic stainless hlau thiab feem ntau tsis yog -sib nqus, txawm hais tias nws yuav pom cov hlau nplaum me ntsis tom qab ua haujlwm txias, tshwj xeeb tshaj yog nyob rau ntawm qhov txiav. Thaum 430 stainless hlau yog hlau nplaum thiab 304 stainless hlau feem ntau tsis yog, tsis yog tag nrho cov hlau nplaum hlau tsis yog 430 stainless hlau, thiab tsis yog txhua yam tsis yog - hlau nplaum hlau yog 304 stainless hlau.
