Qhov twg yog qhov zoo tshaj plaws rau tank ualiab, SS304 lossis SS304L?
Tso lus
Vim li cas cov khoom xaiv teeb tsa rau cov tso tsheb hlau luam?
Thaum ua kom nruj kev tso tsheb hlau luam rau kev ua zaub mov, tshuaj lom neeg, kev ua kom muaj txiaj ntsig, kev coj ua kom zoo dua rau cov qauv kev ua kom zoo nkauj thiab kev ua kom ntev dua qub
Feem ntau cov qhab nia txiav txim siab qib yogSS304thiabSS304L, ob qho tib si yog rau 18-8}}}}}}}}} {}} tab sis dab tsi zoo dua rau cov tsheb thauj khoom?
Qhov sib txawv ntawm SS304 thiab SS304L

Qhov twg yog qhov zoo tshaj plaws rau tank ualiab, SS304 lossis SS304L?
1. corrosion tsis kam
SS304 Stainless HlauMuaj cov ntsiab lus carbon high . hauv cov roj ntsha ua kom haum nrog cov tshuaj chromium (1050℃kub quenching), tab sis nws yuav ua rau kev ua tiav .
SS304L Stainless HlauTsawg cov pa roj tsim teeb txo cov daus los ntawm cov roj nag tsis muaj sia nrog cov pa hluav taws xob hauv tsev, thiab yog qhov ua kom sov
Cov Khoom Siv Neeg Kho Tshuab: Lub Zog
Nyob rau hauv cov kev kub siab ib puag ncig, vim nws cov ntsiab lus carbon ntau, muaj zog dua li ntawm cov neeg muaj zog ntawm 1404L (120MPA)} Tso Tsheb Hlau Luam) .
Tus nqi
Tus nqi ntawm SS304 yog hais txog 10-15% qis dua li ntawm cov SS304L ({}
Piv txwv li, hauv dej hiav txwv cia tank nres dej cog, SS304 yuav tsum tau hloov kho txhua 5 xyoos, txo tus nqi los ntawm tag nrho cov nqi los ntawm 60% {}
SS304 thiab SS304L rau kev tso tsheb hlau luam, yuav ua li cas xaiv?
SS304 Stainless Hlau: Cov Tsheb Tso Tsheb Hlau Luam Yeeb, Tshuaj Ntim Tshuaj Qhuav, Khoom Noj Khoom Haus Qib Khoom Muag Khoom Qib Qib Hauv Nraum
SS304L Stainless Hlau: Vuam yog yuav tsum tau (xws li Orbital Vuam, Tank yuav muab tso tawm cov kab mob vuam (WFI)
Peb pab neeg engineering tuaj yeem pab koj ntsuas kev ua haujlwm, vuam cov cai, vuam
Peb npaj ob qho tib siSS304 thiab SS304L daim hlau, hlab, thiab tank xeemHauv ntau qhov ntau thiab tsawg .
Ob qho SS304 thiab SS304L muaj nyob rau hauv:
