Hauv thaj chaw dav dav ntawm cov ntaub ntawv hlau, cov hlau sib xyaw ua ke thiab cov hlau carbon yog ob pawg tseem ceeb, txhua tus muaj nws qhov zoo hauv kev sib xyaw, kev ua tau zoo thiab kev siv, thiab Jindalai Steel Company, ua tus neeg muag khoom, tau qhia txog kev sib tw muaj zog hauv cov nqe lus ntawm tus nqi.
Cov hlau carbon feem ntau yog ua los ntawm hlau thiab carbon, thiab cov ntsiab lus carbon feem ntau yog nruab nrab ntawm 0.0218% thiab 2.11%. Nws qhov zoo yog tus nqi qis, yooj yim ua thiab weldability zoo, uas ua rau nws siv dav hauv ntau qhov chaw xws li kev tsim kho thiab kev tsim tshuab. Piv txwv li, cov hlau beams thiab cov hlau kem hauv cov qauv tsev feem ntau yog ua los ntawm cov hlau carbon, uas tuaj yeem ua tau raws li lub zog yooj yim thiab cov qauv xav tau ntawm tus nqi qis dua.
Cov hlau sib xyaw ua ke yog ua los ntawm cov hlau carbon thiab ntxiv ib lossis ntau yam khoom sib xyaw, xws li chromium, nickel, molybdenum, thiab lwm yam. Cov khoom sib xyaw no hloov pauv cov yam ntxwv ntawm cov hlau. Cov hlau sib xyaw ua ke muaj zog thiab tawv dua, thiab ua haujlwm tau zoo hauv kev thauj khoom siab thiab siab. Cov khoom tseem ceeb hauv kev tsim khoom siv tshuab, xws li lub cav crankshafts thiab cov bolts muaj zog siab, feem ntau siv cov hlau sib xyaw ua ke. Tib lub sijhawm, nws txoj kev tiv thaiv corrosion thiab kev tiv thaiv kub kuj zoo dua li cov hlau carbon ib txwm, thiab nws muaj txiaj ntsig zoo hauv kev lag luam xws li kev lag luam tshuaj lom neeg thiab aerospace uas muaj cov kev cai nruj rau kev ua haujlwm ntawm cov khoom siv.
Ua ib lub tuam txhab muag khoom, Jindalai Steel Company muab cov hlau sib xyaw ua ke thiab cov hlau carbon zoo tib yam ntawm tus nqi sib tw heev. Hauv kev lag luam ntawm cov hlau sib xyaw ua ke, txawm hais tias cov khoom sib xyaw ua ke tau ntxiv los txhim kho kev ua tau zoo, cov txheej txheem tsim khoom siab heev thiab kev tswj hwm zoo tau txo cov nqi, ua rau cov neeg siv khoom tau txais cov khoom zoo ntawm tus nqi tsim nyog. Rau cov hlau carbon zoo tib yam, qhov zoo ntawm tus nqi kuj pom tseeb vim yog qhov cuam tshuam ntawm qhov ntsuas thiab cov khoom xa tuaj zoo, uas tso cai rau cov neeg tsim khoom, cov chaw tsim khoom, thiab lwm yam kom tswj tau tus nqi zoo thaum ua kom zoo. Txawm hais tias nws yog cov hlau sib xyaw ua ke uas nrhiav kev ua tau zoo lossis cov hlau carbon zoo tib yam uas tsom mus rau kev siv nyiaj tsawg, Jindalai Steel Company tuaj yeem yog tus khub txhim khu kev qha.
