Alloy 316 / 316L yog cov Austenitic alloy thiab zoo ib yam li 304 / 304L yog siv nyob rau hauv ntau cov kev siv. Nws yog ib qho tseem ceeb heev thaum nws los txog ntawm cov chloride ib puag ncig thiab ntau lwm yam kev lag luam tshuaj lom neeg. Qhov sib ntxiv ntawm molybdenum tseem ceeb nce dav corosion ua piv rau 304 / 304L thiab tseem ceeb tshaj plaws, nce chloride pittings.
316 / 316L muaj kev sib sau tau zoo thiab vuam cov yam ntxwv. Vim tias nws cov chloride pitting tsis kam, nws feem ntau siv hauv kev siv uas muaj feem xyuam nrog Chlorides lossis av. Cov cuab yeej ntawd kuj muaj txiaj ntsig hauv cov tub rog ib puag ncig.
Nws tseem muaj qhov tsis kam ua rau muaj kev tiv thaiv zoo rau kev txhim kho corrosion hauv kev ua kom zoo nkauj. Cov qib ob yuav tsum tseem ceeb yog tias muaj kev sib tw ua haujlwm hnyav. Qhov no yog qhov twg intergranular corrosion los rau hauv daim duab thiab muaj qis dua cov pa roj carbon version ua rau nag xob chromium rau hnub nyoog 780 degc) ntau thaum lub vuam yuav mus rau lub sijhawm ntev rau lub ntsuas hnyav.
Nws muaj kev nkag tau zoo heev thiab lub zog tawg ntawm qhov kub siab dua piv rau 304/304L. Thaum kawg, nws muaj lub zog zoo thiab toughness ntawm qhov kub thiab txias.
Cov Ntawv Thov
Dav dav heev. Nws yog xyaum siv yuav luag txhua qhov chaw:
Marine Kev Lag Luam
Tshuaj Yeeb Nkab Vessels
kub exchangers
Khoom Noj Khoom Haus thiab Caw Caw
Kws Tshuaj Kho Mob
kev kho dej
roj av refining
lwm.
