Qhov zoo ntawmcarbon steel yeeb nkab: Cov txheej txheem smelting yog qhov yooj yim, tus nqi qis, kev ua haujlwm siab zoo, kev ua haujlwm zoo thiab cov khoom siv zoo.Xws li los ntawm kev hloov cov ntsiab lus ntawm cov pa roj carbon monoxide thiab rau nws cov kev kho cua sov kom zoo, ntau qhov kev ua tau zoo tau txais los ntawm kev tsim khoom lag luam.Vim tias cov nqi qis carbon steel, kev tsim khoom yooj yim, kev ua haujlwm zoo, kev lag luam tseem yog cov khoom siv hlau siv dav tshaj plaws, cov khoom siv steel suav ntau dua 80% ntawm tag nrho cov nyiaj.

Disadvantages ntawm carbon steel:

(1) Tsis zoo hardenability

Tom qab dej quenching xaiv ntawm carbon steel, quenched rau hauv qhov tseem ceeb txoj kab uas hla ntawm 15 ~ 20mm, 20mm txoj kab uas hla loj dua qhov chaw, txawm tias cov dej tsis tuaj yeem quench hardenability tsis tuaj yeem lav kom tau txais tag nrho cov ntoo khaub lig-section zoo ib yam khoom siv.Yog li ntawd, qhov loj yuav tsum tau siab, carbon steel yeej tsis muaj feem xyuam.Cov alloy muaj siab hardenability tuaj yeem siv los tsim cov ntoo ntoo loj-seem zoo li qhov nyuaj.

(2) Lub zog kub-kub, qis carbon steel, liab hardness txawv

Thaum cov pa roj carbon steel ntawm qhov kub siab tshaj 200℃, nws lub zog thiab hardness yuav sai sai no txo.Qhov zoo stability tom qab tempering alloy.Liab hardness, thiab tuaj yeem ua haujlwm ntawm qhov kub thiab txias.

(3) Kev ua haujlwm tsis muaj zog

Piv txwv li, thaum siv quenched rau try kom tau txais kev ua tau zoo tag nrho, kom ntseeg tau lub zog siab, toughness tsawg, kom ntseeg tau tias zoo dua toughness, siv thiab tsawg.Qhov no yog vim tsis zoo stability ntawm carbon steel tempered vim li cas.Yog li ntawd, qhov tshwm sim carbon steel alloy tsis zoo tag nrho kev ua tau zoo ntau dua li cov alloy muaj qhov zoo robustness.

(4) Tsis muaj kev ua haujlwm zoo

Piv txwv li, yuav tsum tau kub hardness los yog tonicity, antioxidant, corrosion kuj, tshwj xeeb hluav taws xob, sib nqus, thiab lwm yam., tsis tuaj yeem tau nrog carbon steel, alloy steel xaiv kom tau raws li cov kev cai saum toj no xwb.
