Cov Hlau Carbon vs Cov Hlau Me: Nkag Siab Txog Cov Hlau Carbon Dawb thiab Nws Cov Ntawv Siv

Cov hlau carbon dawb, feem ntau hu ua cov hlau carbon xwb, yog cov khoom siv tseem ceeb hauv cov hlaukev tsim khoomNws cov khoom muaj hlau thiab carbon feem ntau, nrog rau cov manganese, silicon, sulfur, thiab phosphorus me ntsis. Cov pa roj carbon feem ntau txiav txim siab nws cov khoom siv kho tshuab. Cov pa roj carbon tsawg ua rau cov hlau mos dua, ductile dua. Cov pa roj carbon ntau dua ua rau muaj kev tawv thiab lub zog tab sis txo qhov ductility.

Cov hlau mos mos sawv cev rau qhov kawg ntawm cov hlau carbon uas muaj cov pa roj carbon tsawg. Feem ntau muaj cov pa roj carbon 0.05–0.25%, nws yooj yim rau vuam, ua duab, thiab tshuab. Nws qhov nyuaj tsawg ua rau nws tsim nyog rau cov khoom siv hauv tsev, cov qauv tsim kho, thiab cov kav dej hlau txheem. Cov hlau nruab nrab thiab cov pa roj carbon siab muaj cov pa roj carbon 0.25–1.0%. Lawv muaj zog dua tab sis tsis yooj yim khoov, yog li lawv feem ntau siv rau hauv cov khoom siv tshuab, iav, thiab cov cuab yeej.

Qhov sib txawv ntawm cov hlau carbon dawb thiab cov hlau tsis hnyav ua kom pom tseeb dua thaum tshuaj xyuas cov khoom tshwj xeeb:

Ib lub hlau mos mosERW yeeb nkabyooj yim khoov thiab vuam. Qhov sib piv, cov hlau carbon nruab nrab nyuaj dua thiab muab kev tiv thaiv zoo dua rau kev hnav, ua rau nws tsim nyog rau cov ntawv thov kev ntxhov siab siab. Qhov sib txawv no cuam tshuam rau ob qho tib si cov txheej txheem tsim khoom thiab cov ntawv thov siv kawg.

Cov hlau carbon yooj yim kuj tseem tuaj yeem piv rau lwm cov ntaub ntawv. Cov hlau tsis xeb muaj tsawg kawg yog 10.5% chromium, muab kev tiv thaiv xeb zoo tab sis tus nqi siab dua, thaum cov hlau carbon pheej yig dua thiab ua haujlwm zoo nrog kev tiv thaiv nto xws li galvanizing lossis pleev xim.

Kev paub txog qhov sib txawv ntawm cov tshuaj lom neeg sib xyaw, cov khoom siv kho tshuab, thiab cov ntawv thov ib txwm pab cov engineers, cov neeg tsim qauv, thiab cov neeg yuav khoom xaiv cov hlau uas tsim nyog. Piv txwv li, cov hlau tsis muaj zog yooj yim rau kev ua duab thiab vuam, ua rau nws zoo tagnrho rau cov haujlwm tsim kho.

Txawm li cas los xij, cov hlau uas muaj cov pa roj carbon ntau dua yuav tiv taus kev ntxhov siab thiab kev hnav, tsim nyog rau cov khoom siv uas nyuaj. Thaum kawg, cov hlau carbon yooj yim sib npaug rau kev siv tau yooj yim nrog kev siv nyiaj tsawg. Cov hlau mos ua rau kev tsim khoom yooj yim, thaum cov carbon muaj zog dua muab kev ruaj khov dua. Kev nkag siab txog cov kev sib txawv no ua kom txhua yam khoom siv ua haujlwm tau zoo tshaj plaws.
