316L 1.4401 tus yeeb nkab stainless hlau yog ib qho kev xaiv yeeb nkab zoo heev thiab cov yeeb nkab ruaj khov siv hauv ntau cov ntawv siv. Qhov no ss s31603 yeeb nkab yog tsim los ntawm cov hlau zoo 316L stainless ua rau corrosion, oxidation thiab staining rau cov chaw hnyav lossis kev siv ntxhov siab.
Tshuab ua haujlwm zoo ib yam li cov khoom siv hardened tsis zoo thiab nws yog ib qho kev ua haujlwm hnyav thiab muaj cov cuab yeej tsis zoo, cov cuab yeej hnyav thiab cov khoom siv ntse. Siv cov tshuab haib thiab hnyav nruj cov cuab yeej.
Lub unr unic s31803 (ASTM F51) Cov lus qhia tshwj xeeb tau ua rau muaj ntau dua Superseded los ntawm Unvent S32205 (1.4462, ASTM F60). Qhov no qhia txog lawv txoj kev xav kom ua kom tiav ntawm cov khoom siv alloy, ua tsaug rau kev txhim kho AOD cov txheej txheem ntawm kev tswj hwm. Ib qho ntxiv, nws tso cai rau cuam tshuam rau cov nitrogen ntxiv qib ntxiv dua li yog tam sim no yog nyob tom qab keeb kwm. Yog li ntawd, qhov siab tshaj plaws ua tiav cov qib hloov kho kom ua kom ntau cov ntsiab lus ntawm chromium (CR), Molybdenum (mo) thiab nitrogen (n).
Peb tus TI Qib 2 Flange, Carbon Steel A694 F60 F65 (TTM ARB, ASTM A182 S32750 Stad Bolt yog qhov tshiab hauv thev naus laus zis thiab tsim nyog hauv cov qauv. Lawv muag tau zoo nyob hauv tsev thiab txawv tebchaws thiab tau txais tos los ntawm cov neeg siv feem ntau. Los ntawm kev ua haujlwm zoo, peb vam tias yuav ua rau muaj kev loj hlob ua kom muaj kev loj hlob ntawm kev tswj hwm ib puag ncig thiab qhov tseem ceeb ntawm cov muaj zog tib neeg cov peev txheej. Tam sim no, peb tab tom siv zog ntxiv rau hauv qhov tshiab ib txwm, cia siab tsim kho tus qauv tshiab ntawm lub tuam txhab kev txhim kho hauv kev coj tshiab. Thaum nkag siab cov ntsiab lus tseem ceeb ntawm kev siv tshuab, lub tuam txhab them ntau dua los muab cov khoom lag luam thiab cov kev pabcuam zoo dua. Cov cuab yeej siv tau zoo heev, cov txuj ci kws tshaj lij, cov kev pab ntau lawm, kev lees paub zoo thiab raws sijhawm tau peb cov neeg siv khoom.
309 stainless hlau. 309s stainless hlau-s30908 (American AISI, ASTM) 309s. Lub 309s stainless hlau tsim los ntawm cov hlau mills yog tiv thaiv ntau rau kev corrosion thiab kub. Muaj peev xwm withstand siab ntawm 980¡Ãc. Mas siv rau hauv boiler, tshuaj thiab lwm yam kev lag luam. Piv nrog 309s, 309 tsis muaj cov ntsiab lus sulphur s.
International Stainless Hlau Txawv Txawv Txoj Cai Lub Tebchaws Asmeskas Hlau thiab Hlau Lub Koom Haum Siv Peb Tus lej los cim ntau cov qauv ntawm cov kab mob stainless. Ntawm lawv: ¢ atausustenitic stainless hlau yog cim nrog 200 thiab 300 series cov lej. For example, some of the more common austenitic stainless steels are marked with 302, 304, 316 and 310, ¢ÚFerritic and martensitic stainless steels are used The number of the 400 series is represented. ¢ferritic stainless hlau yog cim nrog 430 thiab 446, cov xim tawv tawv me me), muaj nag lossis 4%
Qeb 310S Stainless Hlau Taub Hlau Weld Yeeb Nkab Haum muaj cov pa roj hmab ntau, cov roj ntsha li cua sov, cov tshuaj tua hluav taws xob, tshuab ntxhua cua sov, offshore thiab lwm yam.
SAE 304 stainless hlau yog qhov feem ntau steel hlau. Cov hlau muaj ob txoj kev chromium (nruab nrab ntawm 18% thiab 20%) thiab thib pua (nruab nrab ntawm 8%) [1] cov hlau uas yog cov qauv hlau tseem ceeb. Nws yog ib tus neeg siv tshuaj hlau tsis huv. Nws tsis tshua muaj hluav taws xob thiab cuam tshuam cov khoom siv hluav taws xob ntau dua li cov hlau. Nws sib nqus, tab sis tsis sib nqus dua li hlau. Nws muaj ntau dua corrosion tsis kam ntau dua li cov hlau tsis tu ncua thiab siv dav siv vim yog qhov yooj yim nyob rau hauv ntau yam duab. [1]
Cov ntawv no muaj lub zog tensile zoo heev, thiab corrosion tsis kam, thaum tseem nthuav tawm pitting zoo heev thiab kub siab tshaj tawm. Tsis tas li ntawd, nws tau zoo heev depability kom tiv taus cov kua qaub thiab tiv thaiv hnyav huab cua huab cua huab cua.
