Thaum xaiv cov hlau stainless rau kev lag luam lossis kev lag luam ua lag luam, cov neeg yuav khoom sib piv904L stainless hlau vs 304Cov. Ob qho tib si yog nrov, tab sis lawv ua lub hom phiaj sib txawv. Thaum304 Stainless Hlauyog cov qhab nia feem ntau,904L Stainless HlauYog lub siab -} Kev ua tiav alloy tsim rau cov xwm txheej huab. Tsab ntawv no tshawb txog lawv qhov sib txawv tseem ceeb, kev sib piv cov ntaub ntawv, thiab kev siv los pab koj txiav txim siab kom yog.
1. Dab tsi yog 304 stainless hlau?
Hom 304 yog qhov feem ntau dav siv Antenenitic Steel hlau, muaj kwv yees li 18% chromium thiab 8% npib tsib xee. Nws muaj zoo corrosion tsis zoo nyob rau hauv ib puag ncig ib puag ncig, nrog rau kev tsim zoo heev thiab weldability. Nws yog ib qho kev lag luam kev lag luam pheej yig thiab tsim cov khoom siv hauv chav ua noj, thiab cov kav dej tsim tsev, thiab tsis haum rau qhov siab- prloride lossis acidic ib puag ncig.
2. Dab tsi yog 904L stainless hlau?
904L yog super - Austenitic stainless hlau nrog cov ntsiab lus npib tsib caug ntawm 4-23%, thiab cov ntsiab lus tooj liab ntawm 1-2%. Nws muaj zoo heev corrosion ua rau cov sulphoric acid, thiab cosphoric acid, thiab cosphoric acid, thiab cosphoric acid, thiab cosphoricides, muab lub neej kev pab ntau dua nyob rau hauv ib puag ncig hnyav. Thaum nws muaj tus nqi siab dua, nws yuav tsum muaj tsawg dua txoj kev txij nkawm. Nws yog dav siv hauv cov nroj tsuag tshuaj, ua yeeb yam ua lag luam, thiab khoom kim heev khoom lag luam kev lag luam (piv txwv li, Rolex saib cov ntaub ntawv).

Corrosion Kuj
Raws li Super Austenitic Stainless Hlau, 904L Outperforms 304 stainless hlau vim nws lub siab} 15%), molybdenum (1-5%), thiab tooj (1-2%) cov ntsiab lus. Nws ua kom pom zoo nyob deb tshaj rau cov muaj zog muaj zog (piv txwv li sulfuric, phosphoric) thiab crodhe corrosion, thiab kev nyuaj siab corrosion cracking (SCC). Hauv kev sib piv, 304 stainless hlau tsis muaj molybdenum thiab tooj liab, nrog cov ntsiab lus qis dua (8-11%) cov ntsiab lus, ua rau muaj kev haum rau cov chaw qhuav lossis mob me. Nyob rau hauv cov ntsev ntau lossis cov acc acidic, 304 yog nquag mus xeb.
Tus nqi
Vim tias nws qhov siab - Tus nqi ooying ntsiab (tshwj xeeb yog tus loj dua cov hlau uas tau ntau dua li 304 stainless hlau ntau dua. 304 Stainless hlau, nrog nws cov lus yooj yim thiab cov txiaj ntsig zoo dua, ua tau zoo dua, ua tau zoo rau kev xaiv dav dav tsis tas yuav tsum tau ua.
Yog 904L stainless hlau zoo dua 304?
Yog lawm, nyob rau hauv cov nqe lus ntawm corrosion tsis kam thiab durability, tab sis nws kim dua.
