- 201 cov hlau tsis xeb txias yog qhov zoo tshaj plaws thaum cov peev nyiaj, tsos, thiab kev ua tau zoo tseem ceeb dua li qhov siab tshaj plaws tiv taus corrosion.
- Kev dov txias txhawb nqa kev tswj qhov tuab thiab qhov zoo dua ntawm qhov chaw, uas pab txhawb kev stamping, bending, thiab slitting.
- Sab hauv tsev, qhov chaw xeb qis-rau-nruab nrab yog qhov haum tshaj plaws; kev raug dej hiav txwv lossis tshuaj lom neeg hnyav dua feem ntau xav tau 304, 316, lossis lwm qib hloov kho dua tshiab.
201 cov hlau stainless hlau txias dov yog qhov kev xaiv zoo rau cov ntawv thov stainless hlau kauj uas xav tau qhov sib npaug ntawm tus nqi, lub zog, thiab qhov zoo ntawm qhov chaw. Cov kab txaij txias dov thiab daim ntawv feem ntau siv thaum qhov tuab kam rau siab, qhov dav sib xws, thiab qhov tiav du dua tseem ceeb, thiab yog vim li cas 2B lossis lwm yam kev tswj hwm tiav feem ntau tau teev tseg rau cov vaj huam sib luag khoom siv, cov khoom dai kom zoo nkauj, thiab cov khoom tsim. Hauv kev ua haujlwm ntawv thiab kab txaij ntsig txog kev ua haujlwm, kev tswj hwm qhov ntev feem ntau raug xa mus rau cov qauv xws liISO 9445-1, thaum qhov tiaj tiaj thiab cov khoom sib xws kuj feem ntau raug txheeb xyuas hauv cov chaw tsim khoom siv cov txheej txheem tshuaj xyuas sab hauv uas phim nrog kev coj ua hauv kev lag luam. Rau cov neeg yuav khoom sib piv cov qib, lo lus nug tsis yog "cov hlau tsis xeb twg zoo tshaj plaws," tab sis "qib twg haum rau qhov chaw ib puag ncig tiag tiag thiab txoj kev tsim khoom."
Vim li cas 201 txias dov stainless hlau kauj haum rau cov nqi-rhiab stainless hlau kauj daim ntawv thov
201 txias dov stainless hlau kauj yog tsim los rau cov haujlwm uas xav tau kev ua haujlwm stainless hlau yam tsis muaj tus nqi siab dua ntawm 304 lossis 316.
Qhov kev pauv pauv tseem ceeb yog qhov yooj yim: cov ntsiab lus nickel qis dua pab txo cov nqi khoom siv, thaum lub kauj tseem muaj zog thiab zoo li stainless rau ntau yam kev siv sab hauv tsev thiab siv me ntsis. Raws li US Geological Survey cov ntsiab lus mineral rau nickel, nickel yog tus tsav tsheb tseem ceeb hauv ntau cov qauv stainless, yog li txo cov nickel raug tuaj yeem cuam tshuam loj rau kev yuav khoom lag luam ntawm cov ntim loj. Yog vim li cas 201 feem ntau raug xaiv rau cov kev pab cuam uas cov tonnage txhua xyoo siab thiab cov khoom kawg tsis raug rau cov ntsev tsuag tas li, cov kua qaub muaj zog, lossis dej sawv ntsug tas li.
Rau cov pab pawg neeg yuav khoom, qhov zoo tiag tiag tsis yog tsuas yog tus nqi ib yam xwb. Nws yog lub peev xwm los khaws cia qhov zoo nkauj thiab kev ua kom zoo nkauj thaum txo tus nqi tag nrho ntawm kev txiav, kev luam ntawv, thiab kev sib dhos.

| Cov hau ntsaws ruaj ruaj | Kev pom zoo stainless hlau | Kev pabcuam tiv thaiv | Nruab Nrab |
Cov tsev rau khoom siv, cov tub rau khoom pem hauv ntej, thiab cov khoom siv hauv chav ua noj yog cov piv txwv ntau vim tias cov neeg siv khoom pom qhov chaw ua ntej, tsis yog tsev neeg alloy. Cov khoom dai kom zoo nkauj thiab cov qauv npog pom tau kuj tau txais txiaj ntsig los ntawm qhov tiav du dua uas cuam tshuam nrog kev dov txias. Yog tias qhov khoom xav tau kev ua tiav tom qab, xws li embossing lossis kos duab me me, qhov sib xws ntawm cov tuab ntawm lub kauj yuav dhau los ua qhov zoo dua ntawm kev tsim khoom.
Qhov twg 201 txias dov stainless hlau kauj tsis yog qhov kev xaiv zoo tshaj plaws
201 txias dov stainless hlau kauj tsis yog cov lus teb zoo rau txhua daim ntawv thov stainless hlau kauj, tshwj xeeb tshaj yog thaum muaj kev pheej hmoo corrosion siab.
Yog tias qhov chaw ua haujlwm muaj cov tshuaj chlorides, tshuaj tsuag dej hiav txwv, cov tshuaj ntxuav acidic, lossis cov dej ntws tas li, 304 lossis 316 feem ntau yog qhov kev xaiv zoo dua. Kev tiv thaiv xeb ntawm cov hlau tsis xeb yog qhov tshwj xeeb rau kev siv, thiab qhov chaw ib puag ncig feem ntau tseem ceeb dua li cov lus piav qhia hauv phau ntawv teev khoom. Piv txwv li, ib feem zoo sib xws yuav ua haujlwm sib txawv heev hauv cov khoom siv hauv tsev piv rau qhov chaw nyob ntug dej hiav txwv.
Cov lus qhia ASTM muaj txiaj ntsig zoo rau ntawm no vim tias cov neeg yuav khoom feem ntau piv cov qib los ntawm kev cia siab txog tshuaj lom neeg thiab kev kho tshuab. Tsev neeg austenitic stainless hlau tau them dav dav hauv qabASTM A240/A240M, uas yog ib qho ntawm cov ntaub ntawv siv ntau tshaj plaws rau phaj, daim ntawv, thiab daim kab xev siv rau hauv kev siv siab thiab kev siv dav dav. Rau cov neeg yuav khoom, qhov kev kawm yooj yim: kev xaiv qib yuav tsum tau tsav los ntawm kev nthuav tawm, tsis yog tus nqi xwb.
| Qib | Qhov sib npaug ntawm lub zog / corrosion ib txwm muaj | Qhov zoo tshaj plaws siv rooj plaub | Tus nqi txoj haujlwm |
|---|---|---|---|
| 201 | Lub zog zoo, tiv taus corrosion nruab nrab | Cov khoom siv sab hauv tsev uas pheej yig | Qis dua |
| 304 | Kev tiv thaiv corrosion thiab formability sib npaug | Kev siv dav dav hauv kev lag luam thiab kev sib cuag nrog zaub mov | Nruab Nrab |
| 316 | Zoo dua tsis kam rau chlorides thiab cov xov xwm hnyav dua | Kev siv rau hauv dej hiav txwv, tshuaj lom neeg, kev kho mob | Siab dua |
| 430 | Ferritic, sib nqus, pheej yig | Cov khoom siv kho kom zoo nkauj thiab cov khoom siv hluav taws xob sib zog | Qis dua mus rau nruab nrab |
Rau kev sib piv sab hauv ntawm cov tsev neeg khoom, cov neeg yuav khoom feem ntau tshuaj xyuas cov qauv kauj ua ntej xaiv qib. Saibcov hlau tsis xeb, ces xaiv qhov kev xaiv kom me duatxias dov stainless hlau kaujthaum qhov zoo ntawm qhov chaw thiab kev kam rau siab yog qhov tseem ceeb. Yog tias daim ntawv thov xav tau kev tswj hwm qhov dav tom qab hloov pauv,cov hlau tsis xebfeem ntau yog cov kauj ruam tom ntej. Rau cov neeg yuav khoom uas xav tau kev pabcuam tshwj xeeb thiab kev txhawb nqa kev hloov pauv, qhovkev cai stainless hlau kaujnplooj ntawv yog qhov pib tseem ceeb tshaj plaws.
Yuav ua li cas dov txias hloov pauv kev ua tau zoo hauv cov ntawv thov stainless hlau coil
Kev dov txias ua rau muaj kev sib xws, kev ua tiav, thiab kev ua tiav ntawm cov khoom ntau dua li nws hloov zaj dab neeg kev lag luam.
Piv nrog cov khoom siv kub-kub, cov kauj txias-kub feem ntau yog qhov zoo dua thaum qhov khoom yuav raug stamped, khoov, lossis txiav rau hauv qhov dav nqaim nrog cov txiaj ntsig rov ua dua. Cov txheej txheem txo qhov tuab thiab ua kom zoo dua qhov chaw, uas tseem ceeb rau cov khoom pom thiab cov khoom tsim ua tiav. Hauv kev tsim khoom siv, qhov ntawd tuaj yeem txo qhov sib txawv ntawm kev teeb tsa, txo qis kev ua haujlwm rov ua dua, thiab txhim kho kev ruaj khov ntawm kev pub mis hauv cov kab xovxwm.
Kev dov txias tsis ua rau qib qis-xeb mus rau hauv cov hlau marine-grade, tab sis nws ua rau lub kauj yooj yim dua los koom ua ke rau hauv kev tsim khoom rov ua dua. Qhov sib txawv ntawd tseem ceeb hauv cov ntawv thov uas cov txheej txheem hloov pauv tseem ceeb npaum li qhov chaw khoom kawg.
| Qhov tseem ceeb | Txias dov kauj | Kub dov kauj | Vim li cas nws thiaj tseem ceeb |
|---|---|---|---|
| Qhov chaw tiav | Ntxig dua | Rougher | Cov khoom pom tseeb thiab kev nplaum txheej |
| Kev tswj qhov tuab | Nruj dua | Tus neeg xoob | Stamping thiab automated feeding |
| Tsim kom muaj kev sib xws | Siab dua | Nruab nrab | Cov khoov thiab kos duab rov ua dua |
| Kev siv ib txwm muaj | Kev meej thiab tsos | Cov qauv thiab qhov hnyav seem | Daim ntawv thov haum |
Rau kev txheeb xyuas qhov ntev hauv kev hloov pauv coil-to-strip, ntau tus neeg yuav khoom kuj tseem ua kom cov kev kuaj xyuas sab hauv sib haum nrog cov kev coj ua ntsuas thoob ntiaj teb. Lub NIST Digital Library of Mathematical Functions tsis yog tus qauv tsim khoom, tab sis NIST tseem yog qhov chaw siv ntsuas kev ntseeg siab, thiab cov pab pawg tsim khoom feem ntau siv NIST cov ntawv tshaj tawm thiab cov cuab yeej ntsuas taug qab kom cov txheej txheem tshuaj xyuas raug cai. Tus neeg yuav khoom yuav tsum nug txog cov txheej txheem tshuaj xyuas, tsis yog tsuas yog daim ntawv tshaj tawm qib xwb.
