UN tsis yog N02200(Nickel 200) yog cov lag luam nickel forging alloy nrog cov ntsiab lus npib tsib caug thiab muaj hluav taws xob, thiab cov neeg kho kom zoo tshaj qhov ntau ntau.
Nws cov tshuaj lom neeg muaj pes tsawg leeg raug tswj tau nruj me ntsis kom muaj kev ua tau zoo dua li kev siv tshuaj, khoom siv hluav taws xob, aerospace, thiab ua khoom noj.
Cov lus qhia hauv qab no nws muaj pes tsawg leeg, lub luag haujlwm ntawm txhua qhov muaj pes tsawg leeg, thiab lawv cuam tshuam li cov khoom siv li cas.
Unic tsis yog N02200 Tshuaj Muaj pes tsawg leeg tshuaj
Qhov muaj pes tsawg leeg ntawm Nickel 200 tau txhais los ntawm kev txwv nruj me ntsis rau ob qho loj thiab kab kawm, raws li qauv hauv cov lus qhia tshwj xeeb ASTM B160.

Lub siab purity ntawm Nickel 200 yog qhov tseem ceeb rau nws qhov kev ua tau zoo. Tsis zoo li alloy steel, nws tsis muaj ntau cov chromium lossis molybdenum, tab sis relies ntawm cibtic alkalis, thiab tsis yog {2} ecidizing acids.
Txawm tias ib feeb cuam tshuam hauv kev sib xyaw tuaj yeem cuam tshuam ntau rau nws weldability, siab}} kub ua tau zoo, thiab corrosion tsis kam.
Lub luag haujlwm ntawm tsis ua N02200 lub cim tseem ceeb
Lub siab Nickel cov ntsiab lus muab lub ntsej muag ib lub ntsej muag - centre cubic crystal crystal qauv, uas ua kom muaj txiaj ntsig tshwj xeeb thiab tawv txawm nyob ntawm cryogenic kub. Tus qauv no kuj txhawb nqa Alloy's Ferromagnetism thiab kev qhia kub siab.
Lub laj thawj ntawm kev tsim ntawm intermetallic theem, ua nickel 200}}} theem kev coj ua nrog kev coj cwj pwm uas tau pom zoo hauv ib puag ncig.
Cov pa roj carbon ua tib zoo saib xyuas tsawg dua lossis sib npaug rau ntawm 0.15% vim tias nws tuaj yeem ua ntej yog qhov kub hnyiab ntawm 425℃thiab 650℃rau lub sijhawm ntev.
Qhov no nag lossis daus txo cov qauv sib zog thiab txhawb kev txhim kho corrosion. Vim li no, Nickel 200 tsis pom zoo rau kev pab txhawb nqa saum 315 degree; Hloov chaw, qhov qis - pa roj carbon variant Nickel 201 iferred rau high- kev siv kub.
Sulphur tau txwv tsawg dua los yog sib npaug rau 0.01% kom tsis txhob muaj qhov kub. Ntawm qhov kub thiab txias, leej faj tuaj yeem tsim qis dua {2} khib {{}}} Point nickel ntawm cov ciaj ciam av, ua rau tawg. Manganese tau ntxiv rau txo qhov no los ntawm kev tsim cov sulfides sulfides, uas muaj ntau dua melting cov ntsiab lus.
Lwm yam muaj pes tsawg leeg thiab cuam tshuam
Hlau (tsawg dua los yog sib npaug rau 0.40%): Thaum hlau tuaj yeem txhim kho lub zog me me, ntau cov hlau ua kom tsis kam mus rau qee cov kab corrosives. Nws yog khaws qis kom muaj kev coj kom huv ntawm Nickel cov lus teb corrosion.
Tooj liab (tsawg dua los yog sib npaug rau 0.25%): Tooj txhim kho kom tau nyiaj txo cov kua qaub zoo li sulfuric thiab hydrochloric acid. Txawm li cas los xij, hauv Nickel 200, nws yog qhov tsawg heev kom tsis txhob cuam tshuam nrog npib tsib xee nyob rau ib puag ncig ntawm alkaline.
Silicon (tsawg dua los yog sib npaug rau 0.35%): silicon txhim kho oxidation tsis kam thiab deoxidizes cov yaj me me thaum lub sijhawm tsim khoom. Hauv vuam, nws pab tiv thaiv porosity tab sis yuav tsum tau tswj kom tsis txhob ua rau brittleness.
Nickel 200 VS. Npib II
Nickel 201 yog ib qho txawv nrog ib qho cov ntsiab lus roj carbon. Thaum ob qib kawm sib qhia cov kev tiv thaiv zoo ib yam, Nickel 201 yog qhia meej meej tsim rau cov kev pabcuam saum 315℃uas muaj kev pheej hmoo ntawm graphite txaus ntshai yog siab.
Rau feem ntau cov ntawv thov hauv qab no qhov ntsuas kub no, tsib xee tshiab dua li cov ntsiab lus carbon ntau dua thiab tuaj yeem txhim kho chav- kub lub zog me ntsis.
Yuav ua li cas muaj pes tsawg daim ntawv cog lus kev ua tau zoo
Corrosion Kuj: Cov ntsiab lus Nickel cov ntsiab lus muab kev tiv thaiv kom huv si rau chloride kev ntxhov siab thiab tshwj xeeb kev tawm tsam rau caustic dej qab zib thiab lwm yam alkalies.
Fabrication: lub balanced manganese thiab silicon qib ua tau
Cov muaj peev xwm ua tau kub thiab txias heev. Cov Sulfur thiab cov ntsiab lus carbon qis ua kom muaj peev xwm weld zoo los ntawm cov hau kev zoo li Gtaw / TIG thiab GMaw / Mig.
Lub cev muaj lub cev: lub turity ncaj qha cuam tshuam nrog siab sib nqus permeability thiab magnetostrictive cov khoom, muaj txiaj ntsig zoo thiab hloov pauv.
Zoo tshaj plaws corrosion: Lub siab Nickel cov ntsiab lus muab kev ua tau zoo rau caustic alkalis, thiab kev daws teeb meem, thiab kev daws teeb meem nruab nrab, tshwj xeeb tshaj yog nyob rau hauv cov kev mob.
Cov khoom siv zoo: nws muaj cov yeeb yam zoo sib xyaw ntawm lub zog tensile, thiab depility hauv lub anealed mob, uas tuaj yeem hloov kho ntxiv los ntawm kev ua haujlwm txias.
Siab hluav taws xob thiab hluav taws xob conductivity: raws li kev lag luam ntshiab hlau, nws ua rau cov khoom lag luam siab dua piv rau cov hlau hnyav dua.
Muaj txiaj ntsig sib nqus khoom: Nickel 200 yog Ferromagnetic thiab muaj cov txiaj ntsig muaj txiaj ntsig cov khoom siv hlau nplaum.
