Qib 3CR12 stainless hlau yog qib qis tus nqi ntawm chromium uas muaj cov hlau tsis muaj hlau ua los ntawm kev hloov kho cov khoom ntawm qib 409 steel.Nws tiv taus corrosion me me thiab ntub hnav.Nws yog Ameslikas tsim los ntawm Columbus Stainless Company raws li lub npe lag luam "3CR12″.Lwm cov npe rau qib no suav nrog UNS S40977 / S410.
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 tseem suav nrog chav kawm 1.4003, uas yog cov hlau tsis muaj steel rau lub hom phiaj siab.
Cov ntu hauv qab no yuav muab cov khoom tseem ceeb ntawm qib 3CR12 stainless hlau kauj, ntawv thiab phaj ua raws li Euronorm S41003, S40977, ASTM A240 / A240M thiab EN 10088.2 1.4003.
Cov saum toj no tsuas yog cov kev sib piv ntxhib xwb.Cov lus no yog tsim los muab kev sib piv ntawm cov khoom siv sib xws, thiab cov kev qhia tshwj xeeb tsis raug cai.Original specifications tuaj yeem txheeb xyuas yog tias qhov sib npaug yuav tsum tau ua.
Qib 3CR12 stainless hlau tuaj yeem siv rau hauv cov ntawv thov uas aluminium, galvanized lossis carbon steel muab cov txiaj ntsig tsis zoo vim nws tsis kam rau cov kua qaub thiab cov hauv paus, nrog rau kev tawg los ntawm cov tshuaj chloride kev nyuaj siab corrosion.Txawm li cas los xij, tsis zoo li Qib 304, Qib 3CR12 muaj qhov qis tshaj tsis kam rau crevice thiab pitting corrosion nyob rau hauv lub xub ntiag ntawm chlorides.
Nyob rau hauv ambient tej yam kev mob, qib 3CR12 tau txhim kho kev kam rau siab rau cov dej thiab chlorides, raws li cov corrosiveness ntawm cov ntsiab lus chloride yog mitigated los ntawm nitrate thiab sulfate ions.Ib qho tsis zoo ntawm qib 3CR12 yog qhov saum npoo ntawm cov khoom yog me ntsis corroded thaum raug rau tej yam kev siv ntawm ib puag ncig.
3CR12 qib stainless hlau nthuav tawm fouling tsis kam ntawm 600 thiab 750 ° C nyob rau hauv lub xub ntiag ntawm huab cua thiab nruab nrab ntawm 450 thiab 600 ° C nyob rau hauv ib tug pressurized ib puag ncig.Cov khoom yuav nkig nrog ntev raug rau kub ntawm 450 thiab 550 ° C.Txawm li cas los xij, cov khoom tsis poob nws qhov kev cuam tshuam qhov kub thiab txias.
Qib 3CR12 stainless hlau yog annealed ntawm 700 mus rau 750 ° C, muab faib ua 25mm seem, txhua seem soaked rau 1.5 teev.Tom qab ntawd cia cov khoom txias.Care yuav tsum tau coj los tiv thaiv hardening thaum tshav kub kev kho mob.Cov khoom thiab corrosion kuj ntawm qib no yog cuam tshuam los ntawm quenching kev kho mob.
Cov txheej txheem vuam siv rau austenitic stainless hlau tuaj yeem siv rau qib 3CR12 stainless hlau.Xaiv cov khoom siv hluav taws xob qis xws li GMAW (MIG) thiab GTAW (TIG).In vuam, qib 309 muab tub lim xaim ua ntej tau ntawv pov thawj rau AS 1554.6 yog nyiam dua.301MHowever, Cov qib ntawm cov hlau kuj tseem siv tau rau ntau qhov xwm txheej.Txhua yam tsis muaj xim nyob rau hauv cov khoom siv soldered tuaj yeem raug tshem tawm los ntawm kev txhawb nqa roj lossis cov txheej txheem xws li ntxuav thiab pickling.
Lub machinability ntawm 3CR12 qib stainless hlau yog kwv yees li 60% ntawm cov hlau me me.Lawv ua hauj lwm hardening tus nqi qis dua cov austenitic steels, yog li tsis muaj tshwj xeeb machining txoj kev.
Qib 3CR12 stainless hlau los xij muaj nyob rau hauv tus qauv Kub Rolled Annealed thiab Pickled (HRAP) tiav, thiab cov coils muaj nyob rau hauv 2B lossis 2D tiav. Cov xim dub kuj tuaj yeem tsim los ntawm cov khoom kub kub, tawm hauv cov xim dub oxidized ntawm cov hlau.
Nyob zoo Richard, Kuv zoo siab los muab koj cov khoom kom muaj nuj nqis ntawm 3Cr12.Peb muab cov khoom raws li Cromgard C12 hom.Thov hu rau kuv ntawm 719-597-2423.Jane Robinson.
Cov kev xav hais tawm ntawm no yog cov neeg sau thiab tsis tas yuav cuam tshuam txog kev xav thiab kev xav ntawm AZoM.com.
Ntawm Cov Khoom Siv Siab Tshaj Plaws hauv Lub Rau Hli 2022, AZoM tau tham nrog Ben Melrose ntawm International Syalons txog cov khoom lag luam siab heev, Kev Lag Luam 4.0, thiab kev thawb mus rau xoom xoom.
Ntawm Advanced Materials, AZoM tau tham nrog General Graphene's Vig Sherrill txog lub neej yav tom ntej ntawm graphene thiab yuav ua li cas lawv cov khoom siv tshiab yuav txo cov nqi los qhib lub ntiaj teb tshiab ntawm kev siv yav tom ntej.
Hauv kev xam phaj no, AZoM tham nrog Levicron Thawj Tswj Hwm Dr. Ralf Dupont txog lub peev xwm ntawm tus tshiab (U) ASD-H25 lub cev muaj zog spindle rau kev lag luam semiconductor.
