Hauv ntiaj teb ntawm metallurgy, hlau yog ib qho ntawm cov ntaub ntawv siv dav tshaj plaws, thiab nws muaj ntau hom. Ntawm cov no, hlau alloy thiab hlau carbon yog ob hom tseem ceeb tshaj plaws. Txawm hais tias lawv zoo li zoo sib xws thaum xub thawj siab, lawv muaj cov yam ntxwv sib txawv uas ua rau lawv haum rau ntau daim ntawv thov. Hauv cov blog no, peb yuav tshawb nrhiav qhov sib txawv ntawm hlau alloy thiab hlau carbon, yuav ua li cas kom paub qhov txawv ntawm ob qho, thiab cov yam ntxwv tshwj xeeb uas txhua hom hlau muaj.
Cov Hlau Carbon yog dab tsi?
Cov hlau carbon feem ntau yog ua los ntawm hlau thiab carbon, nrog rau cov ntsiab lus carbon feem ntau yog txij li 0.05% txog 2.0%. Hom hlau no paub txog nws lub zog thiab kev ruaj khov, ua rau nws yog qhov kev xaiv nrov hauv kev tsim kho, tsheb, thiab kev lag luam tsim khoom. Cov hlau carbon tuaj yeem muab faib ua peb hom raws li nws cov ntsiab lus carbon: cov hlau carbon qis (txog li 0.3% carbon), cov hlau carbon nruab nrab (0.3% txog 0.6% carbon), thiab cov hlau carbon siab (0.6% txog 2.0% carbon).
Cov Yam Ntxwv Tseem Ceeb ntawm Cov Hlau Carbon
1. "Lub Zog thiab Qhov Nyuaj": Cov hlau carbon yog lub npe hu ua nws lub zog tensile siab thiab qhov nyuaj, tshwj xeeb tshaj yog nyob rau hauv cov qauv carbon siab. Qhov no ua rau nws haum rau cov ntawv thov uas xav tau kev ruaj khov.

Alloy Steel yog dab tsi?
Cov hlau sib xyaw, ntawm qhov tod tes, yog ib hom hlau uas muaj cov ntsiab lus ntxiv, xws li chromium, nickel, molybdenum, thiab vanadium, hauv ntau qhov sib piv. Cov ntsiab lus sib xyaw no tau ntxiv los txhim kho cov khoom tshwj xeeb, xws li lub zog, kev tawv, thiab kev tiv taus kev hnav thiab xeb. Cov hlau sib xyaw tuaj yeem muab faib ua ob pawg tseem ceeb: cov hlau sib xyaw tsawg (tsawg dua 5% cov ntsiab lus sib xyaw) thiab cov hlau sib xyaw siab (ntau dua 5% cov ntsiab lus sib xyaw).
Cov Yam Ntxwv Tseem Ceeb ntawm Cov Hlau Alloy
1. "Cov Khoom Txhim Kho": Kev ntxiv cov khoom sib xyaw ua ke ua rau cov khoom siv kho tshuab ntawm cov hlau zoo dua, ua rau nws tsim nyog dua rau cov ntawv thov uas xav tau ntau.
2. "Kev Tiv Thaiv Kev Xeb": Ntau cov hlau sib xyaw, tshwj xeeb tshaj yog cov uas muaj chromium thiab nickel, ua rau muaj kev tiv thaiv zoo heev rau kev xeb, ua rau lawv zoo tagnrho rau kev siv hauv qhov chaw nyuaj.
3. "Kev Siv Tau Ntau Yam": Cov hlau sib xyaw tuaj yeem tsim kho kom ua tau raws li cov kev xav tau tshwj xeeb, ua rau nws haum rau ntau yam kev siv, txij li cov khoom siv hauv tsheb mus rau cov qauv dav hlau.
4. "Tus nqi": Txawm hais tias cov hlau sib xyaw feem ntau kim dua li cov hlau carbon vim muaj cov khoom sib xyaw ntxiv, nws cov khoom zoo dua feem ntau ua rau tus nqi hauv cov ntawv thov tseem ceeb.
Qhov Sib Txawv Ntawm Cov Hlau Alloy Thiab Cov Hlau Carbon
Qhov sib txawv tseem ceeb ntawm cov hlau sib xyaw thiab cov hlau carbon yog nyob rau hauv lawv cov khoom sib xyaw thiab cov yam ntxwv tshwm sim. Nov yog qee qhov sib txawv tseem ceeb:
