** 1. Cov steel hlau yog dab tsi cov hlau? **
"Carbon Steel" tsis yog ib qib nkaus xwb tab sis muaj qeb dav ntawm cov hlau uas cov khoom sib txuam tseem ceeb yog carbon. Nws tau muab faib ua peb pawg tseem ceeb:
* ** Cov hlau tsis tshua muaj hlau (hlau me): ** ntau heev, siv rau cov qauv qauv qauv, cov ntawv txheeb, thiab xaim xaim.
* ** MENTERLOLOGY STEEL: ** Muaj zog dua li cov hlau tsis tshua muaj roj av, siv rau cov axles tsawg dua, zog, thiab cov shafts.
* ** High cov roj carbon hlau: ** nyuaj heev thiab muaj zog, siv rau cov cuab yeej, siv rau cov xov hlau, thiab cov xov hlau} lub zog.
Cov qhab nia tshwj xeeb hauv cov qauv zoo li AISI / SAE (EG, 1018, 1045) lossis A36, A56).
** 2. Dab tsi yog 304 yeeb nkab qib? **
304 Yeeb Nkab yog hais txog cov yeeb nkab ua los ntawm ** Stainless hlau 304 **. Qhov no yog qhov ntau tshaj plaws thiab ntau yam ustenitic stainless hlau. Nws cov yam ntxwv tseem ceeb yog:
* ** Kev muaj pes tsawg leeg: ** Nws muaj chromium (18-20%) thiab npib tsib xee (8-10.5%).
* ** Qhov khoom: ** Nws muaj cov tshuaj tiv thaiv corrosion zoo heev, muaj kev muaj zog zoo, thiab yooj yim ntawm vuam.
* ** NTXIV siv: ** Nws yog dav siv rau cov kav dej, khoom noj thiab dej haus, tshuaj lom neeg, thiab khoom siv tshuaj lom neeg, thiab khoom siv tshuaj lom neeg.
** 3. Yog Carbon Steel qib 8? **
Tsis yog, qhov no yog qhov tsis meej pem. ** "Qib 8" tshwj xeeb yog hais txog ib chav kawm ntawm siab- Lub zog ua kom muaj zog ntawm cov roj ntsha roj carbon monhoy tau quenched thiab tempered. Thaum lub fasteners yog tsim los ntawm cov pob roj carbon, "carbon hlau" nws tus kheej yog tsev neeg ntau dua. Koj yuav tsis hu rau tus qauv qauv lossis bar ntawm steel "qib 8."
** 4. Yog qib 8 lossis 10.9 muaj zog? **
** 10.9 muaj zog dua qib 8. **
* ** QIB 8 ** yog qhov tsim qauv los ntawm ** SAE ** system (US). Ib qeb 8 ntsia liaj qhov rooj muaj qhov tsawg kawg nkaus tensile lub zog ntawm 150,000 psi.
* ** Chav Kawm 10.9 ** yog qhov tsim qauv los ntawm ** ISO ** Metric System (International). 10.9 ntsia liaj qhov rooj muaj lub zog tsawg kawg ntawm 1,040 MPa, uas yog kwv yees li ** 151,000 PSI **.
Thaum lub zog tensile zoo heev, 10.9 bolts feem ntau muaj lub zog ntau dua, lub ntsiab lus lawv tuaj yeem ua rau lub nra hnyav dua ua ntej deforming. Hauv cov ntsiab lus siv, lawv tau sib ze heev, tab sis 10.9 yog muaj zog thev naus laus zis.
** 5. Yog c45 thiab en8 tib yam? **
Yog lawm, rau cov hom phiaj ua haujlwm feem ntau, ** C45 thiab EN8 tau txiav txim siab sib npaug lossis ze li qub **. Lawv yog ob qho tib si cov pa roj carbon hlau uas muaj cov tshuaj sib thooj thiab cov khoom siv mechanies.
* ** C45 ** yog tus qauv qib los ntawm ** Din (German) ** thiab ** Rau (European) ** tus qauv. Tus "45" qhia tau cov ntsiab lus carbon ntawm kwv yees li 0.45%.
* ** EN8 ** Yog qeb Adritish qib (BS 970) uas tau ntau dua superseded. Nws tseem muaj cov ntsiab lus carbon nyob ib ncig ntawm 0.40%.
Lawv ob leeg feem ntau siv rau cov khoom lag luam engineering zoo li cov shafts, zog, thiab bolts. Thaum cov khoom siv sivcing, lawv feem ntau siv sib hloov pauv.
