U75V yog ib cov roj carbon hlau loj siv cov khoom siv, cov siv hauv kev tsim cov tsheb ciav hlau. Cov hauv qab no yog cov lus qhia ntxaws ntxaws:
Tshuaj lom neeg cov tshuaj:Carbon (c) Cov ntsiab lus feem ntau nyob ib ncig ntawm {{{{}}}}}}}. 80%, manganese (mn) cov ntsiab lus yog nruab nrab ntawm 0.70% {{-1. {}}}}}}}}}}%, Thiab vanadium (v) cov ntsiab lus feem ntau 0.04% {14}}. 12%. Cov pa roj carbon ntau ua kom muaj zog yooj yim thiab tawv tawv ntawm cov hlau; Silicon lub caij muaj peev xwm nce lub zog thiab hardness ntawm cov hlau, txhim kho cov cua sov ua kom tau thiab acid tsis kam ntawm cov hlau; Manganese lub caij muaj peev xwm txhim kho lub zog thiab tawv ntawm cov hlau, txhim kho cov coj tsis kam thiab cov tawv nqaij tawv; Vanadium yog qhov tseem ceeb microalloying keeb, uas tuaj yeem kho cov nplej, txhim kho lub zog, kev coj tsis zoo ntawm cov hlau, thiab txhim kho lub zog qaug zog ntawm cov hlau.
Cov Khoom Siv Neeg Kho Tshuab:U75V muaj lub zog siab thiab ua tau zoo. Nws lub zog tensile feem ntau tsis tsawg dua 980MPA, nws cov txiaj ntsig lub zog tsis tsawg dua 780Mpa, thiab nws elongation tom qab ua pob txha tsis pub tsawg tshaj 7%. Piv nrog differ stail hlau, U75V tau txhim kho lub zog thiab hnav tsis kam, thiab tuaj yeem tiv thaiv lub siab thiab kev sib txhuam thaum lub tsheb ua haujlwm.
Cov yam ntxwv ua:U75V cov khoom yuav tsum tau them sai sai kom tswj cov cua sov kub thiab txias tus nqi thaum ua. Qhov cua sov ntau dhau yuav ua rau kev sib cog qoob loo thiab txo cov kev ua tau zoo ntawm cov hlau; Tus nqi cua txias ntau dhau yuav ua rau muaj kev ntxhov siab sab hauv thiab txawm cog qoob loo. Thaum lub sij hawm rolling txheej txheem, cov txheej txheem dov Piv txwv li, kev siv cov txheej txheem tsawg kub uas tuaj yeem txhim kho lub zog thiab tawv ntawm cov hlau, tab sis tib lub sijhawm nws kuj tso cov khoom siv rau cov yob thiab tswj cov txheej txheem.
Daim Ntawv Thov Teb:Mas siv nyob rau hauv kev lag luam tsheb nqaj hlau, tshwj xeeb tshaj yog nyob rau hauv teb ntawm high-ceev railways thiab hnyav-thau-thauj railwing railways. Nyob rau hauv high-ceev railways, u75v rails tuaj yeem tiv thaiv cov tsheb ciav hlau ceev, ua kom qhov kev nyab xeeb thiab txo cov zaus ntawm kev saib xyuas thiab hloov. Hauv qhov hnyav-thauj kev tsheb nqaj hlau, nws lub zog siab thiab hnav tsis kam tuaj yeem tiv thaiv cov tsheb loj loj, txuas ntxiv cov nqi kev ua haujlwm.
