1. Dab tsi yog SA514 Qib F steel?
SA514 Qib F yog siab -lub zog, quenched thiab tempered alloy steel phaj siv feem ntau hauv cov qauv siv uas yuav tsum tau muaj zog heev thiab muaj zog tawm los, xws li crane booms thiab cov khoom siv mining.
2. Lub zog tawm ntawm SA514 Qib F yog dab tsi?
SA514 Qib F muaj qhov tsawg kawg nkaus yield zog ntawm 100 ksi (690 MPa) rau thicknesses txog 2.5 nti (63.5 hli). Rau cov phaj tuab, qhov tsawg kawg nkaus yield zog txo.
3. Puas yog SA514 Qib F weldable?
Yog lawm, SA514 Qib F tuaj yeem raug welded, tab sis nws yuav tsum tau tswj cov txheej txheem nruj vim nws cov hardenability siab. Preheating, qis-hydrogen electrodes, thiab tswj cov cua sov input yog yuav tsum tau los tiv thaiv hydrogen-induced cracking thiab tswj cov khoom nyob rau hauv lub tshav kub- cuam tshuam cheeb tsam (HAZ).

Yog, tab sis nrog kev nyuaj. Nws yog ib qho nyuaj heev, muaj zog hlau uas yuav tsum tau siv lub tshuab muaj zog, kev teeb tsa nruj, cov cuab yeej txiav tsim nyog (qib thiab geometry), kev ua kom txias txaus, thiab qis dua / pub piv rau cov hlau me me.
9. Qhov sib npaug ntawm SA514 Qib F hauv Tebchaws Europe yog dab tsi?
Tsis muaj qhov ncaj, zoo tib yam European sib npaug. Cov qib ze tshaj plaws nyob rau hauv cov nqe lus ntawm lub zog siab thiab quenched & tempered mob yog S690QL (EN 10025-6) los yog tej zaum Hardox 600 rau hnav daim ntaub ntawv, txawm tias lawv chemistry thiab cov khoom muaj tseeb txawv.
10. SA514 Qib F piv rau T1 steel (A514) li cas?
SA514 Qib F yog T1 steel. "A514" yog ASTM tsim rau cov qauv hlau, thiab "SA514" yog ASME code tsim rau tib yam khoom. Qib F yog ib qho ntawm cov sub- qib tshwj xeeb raws li qhov tshwj xeeb no.
Tag nrho cov specification thiab cov ntsiab lus muaj nyob rau ntawm kev thov. Cov ntaub ntawv saum toj no yog muab rau kev taw qhia nkaus xwb. Rau kev tsim tshwj xeeb thov hu rau peb cov neeg ua haujlwm muag khoom.
