Cov Yeeb Nkab

Cov yeeb nkab steel yog tsuas yog cov yeeb nkab ua los ntawm cov pa roj carbon hlau uas muaj cov ntsiab lus muaj roj carbon ntau. Cov hauv qab no yog cov kev taw qhia nrov rau nws muaj pes tsawg leeg, cov yam ntxwv, kev faib tawm, siv thiab tsim cov thev naus laus zis:
Cov yeeb nkab tseem ceeb: cov yeeb nkab tseem ceeb ntawm cov yeeb nkab steel yog cov hlau thiab carbon, uas cov pa roj carbon, uas yog feem ntau ntawm {}}. 0218% thiab 2.11%. Ntxiv rau cov hlau thiab carbon, nws kuj tseem muaj me me ntawm cov khoom xws li silicon, manganese, phosphorus. Txawm hais tias cov ntsiab lus ntawm cov ntsiab no tsis ntau, nws yuav muaj qhov cuam tshuam tseem ceeb rau kev ua haujlwm ntawm cov kav hlau.
tus yam ntxwv
Muaj lub zog siab: cov yeeb nkab steel muaj lub zog siab thiab tawv tawv, tuaj yeem ua kom muaj qhov hnyav, thiab tsis yooj yim rau qee lub sijhawm uas yuav tsum tau ua kom muaj zog thiab thauj khoom.
Zoo toughness: carbon cov yeeb nkab muaj qhov nyuaj rau tib lub zog, thiab nws tuaj yeem nqus tau lub zog sab nraud, thiab nws tuaj yeem nqus tau qee lub zog thiab muaj kev cuam tshuam zoo.
Zoo machinability: carbon kav hlau yog ib qho yooj yim, lawv tuaj yeem ua rau cov tswv cuab ntawm ntau yam duab thiab txiav kom tau raws li cov haujlwm sib txawv.
Tus nqi qis: piv nrog qee cov khoom tshwj xeeb ntawm cov roj steel, cov nqi ntau dua, yog li nws muaj tus nqi tsim nyog hauv ntau cov teb uas tsis yog xav tau tshwj xeeb ntawm cov khoom siv khoom.
