0cr17ni12mo2Yog tus qauv Suav (GB / T) rau ib qho molybdenum - bearing} cov kabmob Austenitic Stainless Hlau. Nws yog thoob ntiaj teb lees paub raws liAISI 316lossisUNRENT S31600Cov. Cov ntsiab lus tseem ceeb ntawm cov hlau no yog qhov ntxiv ntawm Molybdenum (mo), uas ua rau nws corrosion tsis kam piv rau 304 (0cr18ni9) series.
Cov yeeb nkab steel no yog tsim los ntawm cov txheej txheem zoo li kev sib cog lus lossis vuam, tom qab siv los ntawm kev kho kom sov thiab pickling kom ua tiav kev ua kom zoo corrosion.
1. Lub ntsiab siv thiab cov ntawv thov
0cr17ni12mi12mo2 cov kav hlau steel tau muaj npe rau lawv cov kev ua tau zoo hauv kev ua tiav. Lawv thawj cov ntawv thov suav nrog:
Tshuaj lom neeg thiab petrochemical kev lag luam:
Thauj cov tshuaj tiv thaiv corrosive, acids (zoo li sulfuric acid, phosphoric acid), thiab cov kuab tshuaj.
Pipelines, kev hloov pauv kub, thiab cov hlab ntsha cov nkoj hauv cov nroj tsuag chiv.
Roj thiab roj Kev Lag Luam:
Siv nyob rau hauv ntws los (ntug dej hiav txwv thiab onshore) ib puag ncig, tuav cov roj, roj av, thiab roj nrog cov ntsiab lus siab chloride.
Tubing rau downhole thiab nto kev ua kom tsis kam rau sulfide kev ntxhov siab tawg yog qhov yuav tsum tau ua.
Tubrog Nkoj thiab Cov Ntawv Thov Offshore:
Kev tiv thaiv zoo heev rau Salverwater pitting thiab crevice corrosion ua rau nws zoo tagnrho rau cov kav dej, fittings nkoj, thiab cov nroj tsuag desalination.
Kws Tshuaj thiab Kev Ua Lag Luam:
Thaum 304 yog ib qho muaj, 316 yog siv rau cov cuab yeej siv tau corrosion siab, tshwj xeeb tshaj yog thaum Chlorides nyob hauv cov neeg sawv cev huv lossis cov txheej txheem kwj deg. Nws ua tau raws li cov qauv kev tu cev kom huv.
Lub zog tiam:
Siv nyob rau hauv flue roj desulfurization (FGD) cov tshuab thiab lwm yam kev coj ua corrosive los ntawm - cov khoom.
Architecture thiab kev tsim kho (rau qhov chaw hnyav):
Siv hauv Handrails, Facades, thiab cov qauv hauv cov ntug hiav txwv thaj chaw uas cov tshuaj tsuag ntsev yog qhov teeb meem tas li.
2. Cov ntsiab lus tseem ceeb thiab cov txiaj ntsig
Supior corrosion Kuj:Qhov ~ 2-3% Molybdenum cov ntsiab lus yog tus tseem ceeb tshaj plaws. Nws dastically txhim kho tiv tauspitting thiab crevice corrosion, tshwj xeeb tshaj yog nyob rau hauv chloride {{}} ion ib puag ncig. Qhov no yog nws qhov tseem ceeb tshaj plaws kom zoo dua 304 stainless hlau.
Zoo heev - kub lub zog:Nws tswj hwm cov kev siv tshuab lub zog thiab oxidation tsis kam ntawm nce qhov kub (txog li cas}}}}}}
Fedability zoo thiab weldability:Raws li cov avustenitic steel, nws tuaj yeem yooj yim tsim thiab welded siv cov qauv txheej txheem. Tshaj tawm -} Weld annealing yog pom zoo kom redore ntau corrosion tsis kam nyob rau hauv thaj chaw weld.
Koj cov tawv tawv zoo:Nws khaws cov tawv zoo heev txawm tias ntawm cryogenic kub, ua rau nws haum rau qis - qhov kev siv kub.
Kev ua kom huv thiab kev ua kom zoo nkauj:Nws muaj qhov du, tsis {{0} pav yim npoo uas yooj yim los ntxuav cov kab mob, uas yog cov khoom noj, khoom siv kho mob. Nws kuj tseem muaj kev zoo siab ua kom tiav.
3. Yav Tom Ntej Kev Tsim Kho Kev Nyab Xeeb
Lub neej yav tom ntej rau 0cr17NI12MI2 (316) Cov kav hlau steel tseem zoo nkauj heev, tsav los ntawm kev lag luam thoob ntiaj teb thiab ib puag ncig ua ke:
Kev xav tau kev thov los ntawm cov tub ntxhais ua haujlwm:Kev loj hlob zuj zus hauvTshuaj lom neeg ua yeeb yam, lng (liquefied nkev), thiab cov roj offshore & rojKev tshawb nrhiav tseem yuav yog thawj tsav tsheb. Raws li cov kev lag luam no ua haujlwm nyob rau hauv cov chaw muaj ib puag ncig uas muaj kev txhim khu kev txhim khu kev qha 316 kav yuav ua haujlwm ntev.
Tsom rau ib puag ncig kev tiv thaiv:
Desalination:Lub ntiaj teb thawb rau cov dej tshiab yog coj mus rau ntau cov nroj tsuag desalination, uas tso cia siab loj rau 316 kav dej mus kov dej hiav txwv.
Flue Gas Desulfurization (FGD) thiab Kev Kho Mob Tawm:Stricter ib puag ncig thoob ntiaj teb yuav tsum muaj cov kuab paug tshuaj zoo dua, qhov chaw 316 kav yog ib qho tseem ceeb.
Kev nce qib hauv kev tsim khoom:Kev txhim kho ntawm ntau dua thiab kho cov kev sib txuas lus txuas ntxiv (zoo li kev txuas ntxiv cov cuab yeej vuam thev naus laus zis) yuav txhim kho tus nqi vuam, txo cov nqi, thiab nthuav tawm cov ntawv thov ntau ntawm 316 kav.
Kev Tsim Kho Cov Khoom Siv thiab Tshwj Xeeb:Thaum 316 yog ib tug workfous alloy, nws derivatives zoo li316L (cov pa roj)rau kev txhim kho weld corrosion tsis kam thiab316ti (Titanium -} stabilized)Rau qee qhov siab -} sov daim ntawv thov yuav pom txuas ntxiv kev txhim kho thiab siv tshwj xeeb. Txawm li cas los xij, rau cov xwm txheej hnyav, kev ua lag luam yuav hloov mus rau ntau alloys zoo li Duplex cov hlau (piv txwv li muaj zog dua thiab muaj zog dua.
