Qhov sib txawv tseem ceeb ntawm cov hlau thiab cov hlau dub yog cov hlau yuav tsum tau galvanization vim tias nws muaj kev cuam tshuam rau corrosion thaum cov hlau dub yog tsim los ntawm cov hlau tsis-galvanized.
Cov pa roj carbon steel tau txais nws lub npe vim muaj cov pa roj carbon monoxide ua qhov tseem ceeb. Cov hlau dub tau txais nws lub npe vim muaj cov xim tsaus-xim hlau oxide txheej ntawm cov hlau. Ob daim ntawv no tseem ceeb heev hauv kev tsim cov yeeb nkab.
Carbon Steel yog dab tsi?
Carbon steel yog ib hom hlau uas muaj cov pa roj carbon raws li cov ntsiab lus tseem ceeb. Cov ntsiab lus carbon yog nyob ib ncig ntawm 2.1% los ntawm qhov hnyav. Thaum cov pa roj carbon feem pua nce, qhov hardness ntawm cov hlau nce. Tom qab ntawd nws dhau los ua ductile tsawg.
Daim duab 01: Rolled Sheets ntawm Carbon Steel
Muaj peb hom carbon hlau loj raws li hauv qab no:
Cov pa roj carbon tsawg
Cov pa roj carbon tsawg lossis cov hlau me me muaj cov pa roj carbon tsawg, feem ntau nyob ib puag ncig 0.04-0.30% los ntawm qhov hnyav. Rau ntau daim ntawv thov, daim ntawv no ntawm cov hlau no muaj txiaj ntsig. Lwm cov khoom xws li txhuas tau ntxiv los txhim kho cov khoom ntawm cov hlau.
Medium Carbon Steel
Cov pa roj carbon nruab nrab muaj cov pa roj carbon ntau dua cov pa roj carbon tsawg; feem ntau nyob ib ncig ntawm 0.31-0.60% los ntawm qhov hnyav. Nws kuj tseem muaj ntau npaum li cas ntawm manganese. Daim ntawv no muaj zog dua thiab nyuaj dua li cov pa roj carbon tsawg. Yog li ntawd, nws nyuaj rau txiav thiab vuam cov hlau no.
High Carbon Steel
High carbon steel muaj cov pa roj carbon ntau ntawm 0.61-1.50% los ntawm qhov hnyav. Qee tus neeg hu nws "carbon tool steel". Qhov ntawd yog vim nws lub zog siab thiab hardness uas ua rau nws nyuaj rau txiav thiab vuam.
Dab tsi yog hlau?
Dub steel yog ib daim ntawv uas tsis yog-galvanized steel. Lub npe "dub steel" los ntawm qhov zoo li ntawm cov hlau; nws muaj xim tsaus rau saum npoo ntawm cov hlau vim yog hlau oxide txheej. Cov hlau no tseem ceeb hauv cov ntawv thov uas tsis tas yuav tsum tau galvanized steel.
Daim duab 02: Cov kav hlau dub
Dub steel kav yog cov kav dej uas feem ntau siv hauv kev thauj mus los. Cov kav dej no tuaj yeem tiv thaiv hluav taws zoo dua li cov kav dej galvanized. Tsis tas li ntawd, cov kav dej no muaj txiaj ntsig zoo hauv kev thauj cov dej hauv cov chaw nyob deb nroog vim muaj lub zog siab ntawm cov hlau. Cov kav hlau no yuav tsum tau saib xyuas tsawg dua.
Qhov txawv ntawm Carbon Steel thiab Dub Hlau yog dab tsi?
Carbon Steel vs Dub Hlau |
|
| Carbon steel yog ib daim ntawv ntawm cov hlau uas muaj cov pa roj carbon raws li cov ntsiab lus tseem ceeb. | Dub steel tsis yog-galvanized thiab muaj xim tsaus xim hlau oxide txheej rau saum npoo. |
| Cov ntsiab lus carbon | |
| Muaj cov ntsiab lus carbon txog 2.1% los ntawm qhov hnyav. | Tsis muaj carbon. |
| Hardness | |
| Lub hardness ntawm carbon steel nyob ntawm cov ntsiab lus carbon. | Cov hlau dub muaj lub zog siab thiab tawv. |
| Galvanization | |
| Yuav tsum tau galvanization vim tias cov hlau no muaj kev cuam tshuam rau corrosion. | Yog tsis yog-galvanized steel. |
Summary – Carbon Steel vs Dub Steel
Cov hlau thiab cov hlau dub muaj cov hlau nrog rau qee qhov sib xyaw. Qhov txawv ntawm cov hlau thiab cov hlau dub yog cov hlau yuav tsum tau galvanization vim tias nws muaj kev cuam tshuam rau corrosion thaum dub hlau yog tsim los ntawm cov hlau tsis-galvanized.
