Thaum xaiv cov hlau carbon rau siv rau hauv cov kav dej, cov qauv lossis cov khoom siv tshuab, qhov sib txawv tseem ceeb tshaj plaws yog vim muaj cov pa roj carbon. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias txawm tias qhov kev hloov pauv me me tuaj yeem muaj kev cuam tshuam loj rau lub zog, kev vuam, thiab kev ua tau zoo ntawm cov hlau thaum muaj kev ntxhov siab.
Cov Hlau Carbon Tsawg (Cov Hlau Me): Lub Zog Txhua Hnubnrog Kev Ua Haujlwm Yooj Yim
Cov hlau uas tsis muaj carbon ntau—feem ntau hu uahlau tsis hnyav- siv rau hauv cov khoom uas xav tau kev ua kom zoo nkauj, khoov, lossis vuam xws liCov Yeeb Nkab Hlau Me Me(Hlau Nyias RHS)thiabCov Yeeb Nkab Hlau Me Me(Cov Hlau Me Me SHS). Piv txwv li, feem ntauyeeb nkab plaub fab,lub raj plaub fab, thiab Cov vaj huam sib luag ntawm lub cev tsheb siv dav dav siv cov hlau tsis muaj carbon vim tias nws tuaj yeem tsim tau ntau zaus yam tsis muaj kev tawg.
Cov yam ntxwv tseem ceeb:
Cov pa roj carbon ≤ 0.25%
Yooj yim heev rau vuam
Yooj yim thiab tiv taus kev cuam tshuam
Zoo tshaj plaws rau cov qauv loj thiab cov kav dej
Piv txwv li:
Ib tug neeg siv khoom uas tsim lub tsev rau khoom yuav xaiv cov hlau uas tsis muaj carbon thawj zaug vim tias cov neeg ua haujlwm yuav tsum txiav thiab vuam cov beams ntawm qhov chaw.
Cov Hlau Carbon Siab: Thaum Lub Zog Siab Tshaj Plaws Tseem Ceeb
Cov hlau carbon siab yogtawv heev thiab muaj zog heevvim lawv muaj feem pua ntawm cov pa roj carbon ntau dua. Cov cuab yeej txiav, cov caij nplooj ntoos hlav, cov khoom siv tiv taus hnav, thiab cov ntawv thov uas cov ntaub ntawv yuav tsum tiv tauskev txav mus los lossis kev nyuaj siab rov ua duafeem ntau siv cov hlau carbon siab.
Cov yam ntxwv tseem ceeb:
Cov pa roj carbon ≥ 0.60%
Muaj zog heev thiab nyuaj heev
Nyuaj rau vuam
Kev hnav tsis kam zoo heev
Piv txwv li:
Tus neeg yuav khoom uas tsim cov hniav riam lossis cov ntug txiav yuav ib txwm nyiam cov hlau carbon siab vim nws tuaj yeem tswj tau ntug ntse ntev dua.
Carbon Steel vs Steel: Vim li cas cov lus no thiaj tsis meej pem
Muaj ntau tus neeg yuav khoom nug "carbon steel vs steel", tab sis hlau yog ib lo lus dav dav. Carbon steel tsuas yog ib pawg ntawm cov hlau, ua los ntawm hlau thiab carbon. Lwm hom hlau suav nrog alloy steel thiab stainless steel.
Cov Hlau Carbon vs Cov Hlau Mos: Kev Nkag Siab Yuam Kev Feem Ntau
Cov hlau tsis muaj zog tsis sib cais los ntawm cov hlau carbon - nws yog cov hlau carbon qis.
Qhov txawv yog lub npe, tsis yog cov khoom siv.
Yog tias ib qho project xav tau kev vuam thiab ua kom yooj yim, cov hlau tsis muaj zog yuav luag txhua zaus yog qhov kev xaiv pom zoo.
Piv txwv luv luv
Cov hlau carbon tsawg/hlau mos:
l Cov thav duab rau khoom, cov kav hlau, cov vaj huam sib luag tsheb
Cov hlau carbon siab:
l Cov cuab yeej, cov hniav, cov caij nplooj ntoos hlav lag luam
Cov hlau carbon piv rau cov hlau:
l Cov hlau carbon yog ib hom hlau
Cov hlau carbon piv rau cov hlau tsis muaj zog:
l Hlau mos = hlau carbon tsawg
