Qib 3CR12 stainless hlau yog qib pheej yig ntawm chromium muaj stainless hlau ua los ntawm kev hloov kho cov yam ntxwv ntawm qib 409 hlau. Nws tiv taus kev xeb me me thiab hnav ntub. Nws tau tsim los ntawm Columbus Stainless Company raws li lub npe lag luam sau npe "3CR12". Lwm lub npe rau qib no suav nrog UNS S40977 / S41003 thiab 1.4003.
Lwm cov npe sib npaug rau 3CR12 qib suav nrog ASME SA240 qib, ASTM A240/A240M qib, thiab EN 10088.2. Txawm li cas los xij, EN 10028.7 kuj suav nrog chav kawm 1.4003, uas yog cov hlau tsis xeb rau lub hom phiaj siab.
Cov ntu hauv qab no yuav muab cov khoom tseem ceeb ntawm qib 3CR12 stainless hlau kauj, daim ntawv thiab phaj raws li Euronorm S41003, S40977, ASTM A240/A240M thiab EN 10088.2 1.4003.
Cov saum toj no tsuas yog kev sib piv xwb. Cov lus qhia no yog los muab kev sib piv ntawm cov ntaub ntawv zoo sib xws, thiab cov lus qhia tsis raug cai. Cov lus qhia qub tuaj yeem txheeb xyuas tau yog tias xav tau cov khoom sib npaug.
Qib 3CR12 stainless hlau siv tau rau hauv cov ntawv thov uas txhuas, galvanized lossis carbon hlau muab cov txiaj ntsig tsis zoo vim nws tsis kam rau cov kua qaub thiab cov hauv paus muaj zog, nrog rau kev tawg los ntawm chloride kev ntxhov siab corrosion. Txawm li cas los xij, tsis zoo li Qib 304, Qib 3CR12 muaj qhov tsis kam qis tshaj plaws rau crevice thiab pitting corrosion nyob rau hauv qhov muaj chlorides.
Nyob rau hauv cov xwm txheej ib puag ncig, qib 3CR12 tau txhim kho kev kam rau dej thiab chlorides, vim tias qhov corrosiveness ntawm cov ntsiab lus chloride raug txo los ntawm nitrate thiab sulfate ions. Ib qho ntawm cov teeb meem tseem ceeb ntawm qib 3CR12 yog tias qhov chaw ntawm cov khoom siv yog me ntsis corroded thaum raug rau txhua hom ib puag ncig. Nws yog vim li no tias cov khoom siv tsuas yog txwv rau cov ntawv thov kho kom zoo nkauj.
Cov hlau tsis xeb qib 3CR12 ua rau muaj kev tiv thaiv fouling ntawm 600 thiab 750 ° C nyob rau hauv qhov muaj huab cua thiab ntawm 450 thiab 600 ° C nyob rau hauv ib puag ncig muaj siab. Cov khoom siv ua brittle nrog lub sijhawm ntev rau qhov kub ntawm 450 thiab 550 ° C. Txawm li cas los xij, cov khoom siv tsis poob nws qhov kev tiv thaiv cuam tshuam hauv qhov kub no.
Qib 3CR12 stainless hlau yog annealed ntawm 700 txog 750 ° C, muab faib ua 25mm seem, txhua seem ntub rau 1.5 teev. Tom qab ntawd cia cov khoom txias. Ceev faj yuav tsum tau ua kom tsis txhob tawv thaum kho cua sov. Cov khoom siv kho tshuab thiab kev tiv thaiv corrosion ntawm qib no raug cuam tshuam los ntawm kev kho quenching.
Cov txheej txheem vuam siv rau cov hlau tsis xeb austenitic tuaj yeem siv rau cov hlau tsis xeb qib 3CR12. Xav txog cov thev naus laus zis qis xws li GMAW (MIG) thiab GTAW (TIG). Hauv kev vuam, qib 309 filler hlau uas tau ntawv pov thawj ua ntej rau AS 1554.6 yog qhov zoo dua. Txawm li cas los xij, qib 308L, 316L, 309Mo thiab 309L ntawm cov hlau kuj siv rau hauv ntau kis. Txhua qhov xim tsis zoo hauv cov khoom vuam tuaj yeem tshem tawm siv cov roj txhawb nqa lossis cov txheej txheem xws li kev ntxuav thiab pickling.
Qhov kev siv tshuab ntawm 3CR12 qib stainless hlau yog kwv yees li 60% ntawm cov hlau tsis muaj zog. Lawv qhov kev ua haujlwm tawv qis dua li ntawm cov hlau austenitic, yog li tsis tas yuav muaj cov txheej txheem tshwj xeeb.
Cov ntawv hlau stainless hlau qib 3CR12 muaj nyob rau hauv tus qauv kub dov Annealed thiab Pickled (HRAP) tiav, thiab coils muaj nyob rau hauv 2B lossis 2D tiav. Cov xim dub kuj tseem tuaj yeem tsim los ntawm cov khoom siv kub dov, tawm hauv qhov chaw dub oxidized ntawm cov hlau. 3CR12 qib dub tiav muaj kev tiv thaiv corrosion zoo thiab kev sib txhuam qis, yog li nws tsim nyog rau ntau yam kev siv hnav.
Nyob zoo Richard, kuv zoo siab muab 3Cr12 rau koj. Peb muab cov khoom siv raws li hom Cromgard C12. Thov hu rau kuv ntawm 719-597-2423. Jane Robinson.
