Monel 404 Alloy Sawb (ASTM F96 / W.Nr. 2.4867)

Khoom Taw Qhia

Monel 404 (feem ntau hu ua Alloy 404) yog npib tsib xee - tooj liab alloy. Nws muaj ob qhov zoo: ua ntej, nws cov coefficient ntawm thermal expansion zoo ib yam li cov iav, kom ntseeg tau tias cov khoom yuav tsis tawg lossis xau thaum cov hlau thiab iav raug kaw ua ke. Qhov thib ob, nws cov hlau nplaum yog negligible; nyob rau hauv lub xeev annealed, nws permeability tuaj yeem ncav cuag 1.0017 max (tsis yog-magnetic), txhais tau tias nws yog ib qho tseem ceeb rau kev tiv thaiv cov teeb liab distortion ntawm txhua yam khoom siv hluav taws xob.

Raws li peb cov lus nug yav dhau los nrog Alloy 404 cov neeg siv khoom, nws yog qhov siab -kawg, kev cai- tsim cov khoom siv nrog "precision lub cev" tshwj xeeb rau cov iav / ceramic sealing daim ntawv thov uas xav tau cov khoom sib nqus tsawg heev. Hauv lwm lo lus, cov neeg siv uas yuav Alloy 404 tapes feem ntau siv lawv rau cov khoom siv hluav taws xob nqus tsev, cov tsev nyob hauv transistor, lossis cov kev sojntsuam precision uas yuav tsum tau muab cov iav sealing. Feem ntau, nws yog qhov yuav tsum tau yuav cov qauv ua ntej, tshwj xeeb tshaj yog rau cov iav sealing daim ntaub ntawv. Cov qauv me me tau yuav ua ntej los ua qhov kev sim sealing kom paub meej tias thermal expansion txuam thiab airtightness tsis yog ib qho teeb meem ua ntej muab qhov kev txiav txim loj.

Cov khoom lag luam xwm txheej

1. Cov Qauv Ua Haujlwm:

Zoo li tib neeg, Monel 404 alloy khoom kuj muaj nws tus kheej tus lej cim. 404 alloy peb feem ntau muab los nrog cov qauv siv tshwj xeeb rau kev siv sib txawv kom ntseeg tau tias peb xa cov khoom tsim nyog. Hauv qab no yog qee yam ntawm peb cov qauv siv tau:

ASTM B127: Nickel- tooj liab alloy daim ntawv txheem, muaj feem xyuam rau strips.

ASTM F96 1: Cov txheej txheem tshwj xeeb rau nickel alloy strips rau kev siv hluav taws xob; pom zoo kom siv thaum tsim khoom siv hluav taws xob.

UNS N04404 / W.Nr. 2.4867: Tus nab npawb ntawm cov khoom siv.

2. Nqe thiab Nqi:

Tus nqi raw khoom ntawm Alloy 404 feem ntau cuam tshuam los ntawm cov nqi ntawm cov npib tsib xee thiab tooj liab. Kev hloov pauv hauv LME npib tsib xee thiab tus nqi tooj liab tuaj yeem ua rau tus nqi hloov pauv txhua hli.

Tus nqi ntawm Alloy 404 sawb yog xam raws li kev sib xyaw ntawm thickness, dav, hardness, thiab kom muaj nuj nqis. thinner thiab nqaim strips yog kim dua. Precision electronic-qib strips yog kim dua industrial-qib strips.

3. Muaj peev xwm Warranty:

Warranty Capabilities: Thaum tshuaj xyuas cov lus hais, peb kuj xav txog peb cov ntawv pov thawj thiab muaj cov khoom siv tes tuav spectrometer (rau kev ntsuam xyuas cov tshuaj muaj pes tsawg leeg ntawm cov khoom). Tsis tas li ntawd, seb peb puas tuaj yeem muab daim ntawv tshaj tawm kev ntsuas magnetic permeability (them thib peb-kev kuaj xyuas tog) cuam tshuam ncaj qha rau koj cov khoom lag luam.

Kev ua haujlwm nyuaj thiab cov ntsiab lus tseem ceeb

Monel 404 muaj machinability zoo dua li feem ntau cov nickel-raws li alloys. Nws txoj kev xa khoom-annealed lossis txias-rolled- thiab nws cov tawv nqaij ncaj qha cuam tshuam rau nws cov formability; cov neeg siv uas xav mus ntxiv cov txheej txheem nws yuav tsum tau them sai sai rau cov yam ntxwv no.

1. Stamping / Deep Drawing: Nws muaj cov yas zoo tab sis yuav "harden".

Alloy 404 nthuav qhia kev ua haujlwm tseem ceeb, ua nyuaj ntxiv thaum lub sij hawm sib sib zog nqus. Peb feem ntau pom zoo kom cov neeg siv khoom xaiv lub xeev annealed; ib qho elongation ntawm ntau dua 35% hauv lub xeev annealed yog tsim nyog rau kev kos duab kom zoo.

Qhov kev tshem tawm tuag yuav tsum yog 10-15% loj dua li cov hlau tsis zoo tib yam, thiab cov roj viscosity siab yuav tsum tau siv rau lubrication kom zoo.

Qhov tseem ceeb tshaj plaws, yog tias qhov tob tob yog qhov loj heev (piv txwv li, ntau tshaj ob zaug ntawm txoj kab uas hla), nws yuav tsum tau muab tshem tawm ib nrab los ntawm kev muag muag ua ntej ua haujlwm.

2. Khoov:

Lus Cim: Alloy 404 muaj cov yas zoo hauv lub xeev annealed, tso cai rau me me dabtsi yog khoov radii, tab sis lub springback yog ntau dua li ntawm cov hlau tsis zoo tib yam, yuav tsum tau sim molding thiab hloov.

Qhov no yog qhov uas tus nqi ntawm kev yuav Monel 404 alloy sawb lus dag.:

Sib nqus Permeability (annealed xeev): Tsawg dua lossis sib npaug rau 1.0017- Qhov no yog nws tus yam ntxwv txhais.

Coefficient ntawm Thermal Expansion: 13.3 μm / m ·℃ntawm 70-200℃F, sib xws nrog qee hom iav.

Elastic Modulus: 169 GPa

Daim ntawv tshwj xeeb:Alloy 404 muaj lub zog qis, tab sis qhov no tsis yog qhov tsis zoo - nws yog tsim los ua mos thiab yooj yim rau pwm. Yog tias koj xav tau siab -lub zog elastic Cheebtsam, peb xav kom xav txog Alloy K500 lossis lwm qib.

Cov ntsiab lus tseem ceeb ntawm kev soj ntsuam zoo

Thaum tau txais cov khoom, peb yuav ua qhov kev tshuaj xyuas thawj zaug thiab rov ua dua thib ob -kev tshuaj xyuas ntawm Monel 404 alloy strip, muab piv rau cov qauv ua tiav thiab cov neeg siv khoom xav tau. Ntau qhov kev kuaj ntsuas tau ua los xyuas kom meej tias cov khoom xa tuaj siab npaum li cas. Qhov tseem ceeb, txhawm rau tiv thaiv tom qab- teeb meem kev muag khoom xws li cov khoom tsis xws luag thaum tau txais cov neeg siv khoom, peb feem ntau khaws cov qauv hauv peb chav kuaj ntsuas tus kheej, khaws cia cov duab sim thiab cov yeeb yaj kiab ua haujlwm rau kev taug qab.

Kev tshuaj xyuas thawj zaug suav nrog tsib qhov kev kuaj xyuas: specifications, kom muaj nuj nqis, tolerances, nto zoo, thiab ntim.Piv txwv li:

• Dimensional kam rau ua:Lub thickness thiab dav ntawm Alloy 404 sawb raug soj ntsuam ntawm ntau lub ntsiab lus siv lub micrometer. Ntug burrs yog ua tib zoo tshuaj xyuas.
• Nto zoo:Alloy 404 sawb yog nquag khawb, indentations, thiab roj stains. Qhov pib thiab qhov kawg ntawm lub kauj yog ua tib zoo tshuaj xyuas thaum lub sij hawm unpacking.

Qhov thib ob rov- kev tshuaj xyuas suav nrog 3-6 qhov kev sim cov ntaub ntawv tshwj xeeb, xws li tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv kho tshuab, ntsuas qhov tawv tawv, thiab cov khoom kuaj tshwj xeeb(Cov khoom siv alloy 404 yuav tsum tau kuaj cov hlau nplaum). Ua raws li lub hauv paus ntsiab lus ntawm "tus qauv siv raws li lub hauv paus, thiab tshuaj tua kab mob thiab kev siv cov cuab yeej ntsuas kom zoo raws li lub hauv paus," ntau yam random checks thiab cov ntaub ntawv sib piv yog ua los xyuas kom meej cov "kev raug" ntawm cov ntaub ntawv.

• Chemical Composition Report:Spectroscopic tsom xam daim ntawv qhia. Ua kom pom tseeb ntawm nickel (Ni) 52-57%, hlau (Fe) Tsawg dua lossis sib npaug li 0.5%, thiab silicon (Si) Tsawg dua lossis sib npaug li 0.1%.

Mechanical Properties: Tshawb xyuas lub zog tawm los thiab elongation ntawm Alloy 404 sawb. Cov ntaub ntawv nrog qhov elongation qis dua 35% hauv lub xeev annealed yog suav tias tsis tsim nyog.

• Kev kuaj Hardness:Annealed Alloy 404 feem ntau sim siv HRB, nrog rau qhov hardness kwv yees li ntawm 60-80 HRB. Cov txiaj ntsig tshwj xeeb yuav tsum tau txiav txim siab raws li kev siv Alloy 404 tus qauv. Rau nyias strips, nto Rockwell los yog Vickers hardness yog siv.
• Magnetic Testing (Critical!):Yog tias siv nyob rau hauv qhov qis -ib puag ncig sib nqus, daim ntawv qhia kev sib nqus permeability rau Alloy 404 yog qhov tsim nyog. Qhov permeability hauv lub xeev annealed yuav tsum tsawg dua lossis sib npaug rau 1.0017.
