Dab tsi yog Nickel 200 siv rau

1. Dab tsi yog Nickel 200 siv rau?

Nickel 200 yog cov neeg lag luam nickel alloy (nrog cov ntsiab lus npib tsib.6% lossis siab dua corrosion tsis kam, thiab thermal / hluav taws xob conductivity. Nws cov ntawv thov feem ntau yog tsav los ntawm cov khoom no, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas tsis kam rau tshuaj thiab siab heev yog qhov tseem ceeb. Cov siv sib xws li suav nrog:

Kev Lag Luam: Nws yog dav siv hauv cov cuab yeej siv xws li tso tsheb hlau luam, kav dej, thiab twj uas kov cov xov xwm zoo li alkalis hydroxide), organic acids, thiab cov ntsev thiab nruab nrab. Nws txoj kev tiv thaiv kom corrosion los ntawm dej thiab chav ntawm qhov kub siab kuj ua rau nws haum rau kev hloov cua sov hauv cov nroj tsuag tshuaj lom neeg.

Hluav taws xob thiab kev lag luam hluav taws xob: Vim tias nws cov hluav taws xob siab thiab tsis tshua muaj kev tiv thaiv kab mob siab, piv txwv li, hluav taws xob rau cov roj teeb alkaline), cov xov hluav taws xob, thiab cov xov hlau txhuas.

Tubrog Nkoj thiab Cov Ntawv Thov Offshore: Nws tiv thaiv corrosion los ntawm seawater thiab ntsev zoo rau cov marine kho vajtse, undershore roj rig Cheebtsam.

Khoom noj khoom haus thiab khoom lag luam: Nws lub siab purity thiab resistance rau corrosion los ntawm cov khoom noj acids (piv txwv li cov tso tsheb hlau luam, thiab cov tshuaj tso tawm.

Nuclear Engineering: Nws yog siv nyob rau hauv qee lub chaw nuclear rau nws txoj kev tiv thaiv kom tawg-inducter thiab corrosion thiab compatibility nrog txias.

2. Dab tsi yog qhov muaj pes tsawg leeg ntawm Ni200?

Nickel 200 yog qhov muaj txiaj ntsig zoo-purity cockel alloy nrog qhov sib xyaw ua ke hauv qab no (los ntawm qhov hnyav):

Npib tsib caug (ni): 99.6% yam tsawg kawg (feem ntau 99.8-99.9%).

Carbon (c): 0.10% siab tshaj plaws.

Hlau (FE): 0.4% siab tshaj plaws.

Tooj Liab (Cu): 0.25% qhov siab tshaj plaws.

Manganese (mn): 0.35% siab tshaj plaws.

Silicon (si): 0.35% siab tshaj plaws.

Lwm yam tsis zoo: Cov nqi nyiaj (piv txwv li, leej faj, phosphorus) tag nrho tsawg dua 0.1%.

Cov ntsiab lus no loj npib ob leeg ua kom tau nws cov yam ntxwv tseem ceeb, xws li corrosion tsis kam thiab ductility.

3. Dab tsi kub yog Nickel 200 annealing?

Annealing Nickel 200 yog ib txheej txheem kho cua sov siv los soften cov khoom, txhim kho kev ntxhov siab (piv txwv li, tom qab ua haujlwm txias). Cov annealealing kub ntau rau rau npib tsib xee 200 yog700 Qib rau 950 Qib (1,292 Qib F rau 1,742 Qib F).

Rau siab tshaj plaws muag thiab ductility, ntsuas kub ib ncig 870℃(1,600℃f) yog feem ntau siv.

Cov khoom siv tau nyob rau ntawm qhov kub no rau 30 feeb rau 2 teev (nyob ntawm cov tuab) thiab tom qab ntawd txias qeeb (piv txwv li cua lossis cua sov) kom tsis txhob rintsrododucing kev ntxhov siab.

Tus txheej txheem no rov qab ntawm alloy mallability, ua rau nws yooj yim dua rau cov qauv ua ke (piv txwv li cov ntawv, cov hlab) yam tsis tau tawg.

4. Dab tsi yog cov khoom ntawm Nickel 200 thiab 201?

Nickel 200 thiab 201 yog ob qho tib si ua lag luam alickel alloys nrog cov khoom zoo sib xws, tab sis lawv sib txawv me ntsis hauv cov ntsiab lus carbon, uas cuam tshuam rau lawv cov kev ua tau zoo ntawm kev kub siab. Nov yog lawv cov yam ntxwv tseem ceeb:

Cov khoom ntawm Nickel 200 thiab 201:

Corrosion Kuj: Zoo heev tiv thaiv rau Alkalis, dej, Chav, thiab ntau cov organic / inorganic tshuaj. Lawv yog tshwj xeeb tiv taus corrosion hauv qhov chaw tsis-oxidizing (piv txwv li hydrochloric acid ntawm tsawg kub).

Ductility thiab formability: Heev coo, txawm tias ntawm tsawg kub, tso cai rau kev ua haujlwm txias (piv txwv li, dov, khoov, khoov, khoov, khoov) thiab kub.

Thermal conductivity: ~ 70 w / (MISK k) ntawm 20℃(zoo ib yam li ob lub ntsej muag Nickel), ua rau muaj kev hloov pauv kub.

Hluav Taws Xob Kev Tshaj Tawm: ~ 22% IRCS (International Analaled Tooj Liab Qauv), ua rau lawv zoo hluav taws xob.

Cov Khoom Sib Nqus: Ferromagnetic (nyiam rau cov hlau nplaum) ntawm chav tsev kub, tab sis poob Magnetism saum toj no lawv txoj kev foom (~ 358℃rau Degree Nickel).

Melting point: ~ 1,455℃(2,651℃f).

Hauv cov ntsiab lus, Nickel 200 yog nyiam rau cov kev siv hluav taws xob dav dav, xws li hloov pauv kub, kev ua kom sov siab) qhov twg kub hloov) qhov twg cov pa hluav taws xob) qhov twg ua kom sov so.
