U75V thiab U71MN yog ob tug sib tw ciav hlau. Ntawm no yog qhov sib piv ntawm lawv:
Tshuaj Muaj Tshuaj
U75V: Cov ntsiab lus carbon yog qhov tseem ceeb, txog {{{{} {}}}}}}} Kuj muaj 0.04% {14 14}}. 12% vagadium.
U71mn:Cov ntsiab lus carbon feem ntau yog feem ntau ntawm {{{{4 {} {} {{{{{-1. 50%, thiab nws tsis muaj vanadium.
Cov Khoom Siv Neeg Kho Tshuab
U75V: Lub zog tensile tsis tsawg tshaj li 980MPA, cov txiaj ntsig muaj zog tsis tsawg dua 780MPA, thiab lub elongation tom qab pob txha lov yog tsis tsawg dua 7%. Vim tias nws muaj vanadium, nws lub zog, tawv thiab hnav tsis kam yog qhov zoo, tshwj xeeb yog nws nkees tsis kam.
U71mn:Lub zog tensile feem ntau tsis tsawg dua 880MPA, cov txiaj ntsig lub zog tsis muaj tsawg dua 580MPA, thiab lub elongation tom qab pob txha tsis pub tsawg tshaj li 9%. Nws lub zog thiab hardness kuj tseem tuaj yeem ua tau raws li cov kev cai ciav hlau, tab sis nws qis dua me ntsis rau U75V hauv lub zog thiab nkees ua yeeb yam.
Ua teeb meem nyuaj
U75V:Vim tias nws muaj vanadium, cov txheej txheem tsis tas yuav tsum tau tswj hwm kom tsis txhob hloov pauv ntawm cov khoom siv hlau vim yog tus ntawm vanadium. Piv txwv li, kev kub siab dhau heev yuav ua rau muaj kev sib tw ntawm Vanadium carbides, uas yuav cuam tshuam rau cov qauv thiab cov khoom ntawm cov hlau tom qab txias; Sai sai dua ib lub cua txias cua txias yuav ua rau muaj kev ntxhov siab rau sab hauv thiab nce kev pheej hmoo ntawm cov kab nrib pleb.
U71mn:Kev ua nyuaj yog qhov tseem ceeb me me, thiab kev tswj hwm yuav tsum muaj rau cov txheej txheem tsis yog ua nruj raws li U75V. Txawm li cas los xij, vim nws cov ntsiab lus manganese, nws kuj yog qhov tsim nyog kom tswj kev ua kom sov thiab nrawm thaum ua cov teeb meem xws li ua haujlwm tawv.
Daim Ntawv Thov Kev Pab Cuam
U75V: Haum rau cov xwm txheej nrog cov kev xav tau siab rau kev ua haujlwm ntawm kev ua haujlwm, xws li cov tsheb ciav hlau siab thiab hnyav-railways. Nyob rau hauv high-ceev railways, nws tuaj yeem tiv taus cov kev tsheb ciav hlau siab kom ntseeg tau tias qhov ruaj khov thiab kev nyab xeeb ntawm txoj kev khiav; Hnyav Hnyav Lub Luag Haujlwm Railways, nws lub zog siab thiab hnav tsis kam tuaj yeem tiv thaiv cov tsheb loj, thiab nthuav tawm lub neej ntawm kev tsheb nqaj hlau.
U71mn:Mas siv rau cov tsheb ciav hlau dav dav, xws li cov kab thauj khoom zoo ib yam li cov neeg caij npav nrog cov neeg caij npav me. Hauv cov xwm txheej no, U71MN tuaj yeem ua tau raws li kev siv ntawm cov kev yuav tsum tau ua ntawm cov kev cai thiab muaj qee yam nqi zoo.
Tus nqi
U75V: Vim yog qhov sib ntxiv ntawm aluminium ntsiab xws li Vanadium thiab High Xav Tau rau cov txheej txheem ntau lawm, cov nqi ntau lawm yog qhov siab.
U71mn:Nws tsis muaj cov khoom siv hlau nplaum, cov txheej txheem ntau lawm yog qhov yooj yim, thiab tus nqi yog tsawg.
