1. Dab tsi yog SA514 Qib E steel?
SA514 Qib E yog siab - lub zog, quenched thiab tempered alloy steel phaj nyob rau hauv ASTM A514 / SA514 specification, tsim rau cov ntawv thov uas yuav tsum tau muaj ib tug sib npaug ntawm high yield zog thiab zoo heev toughness.
2. Lub zog tawm ntawm SA514 Qib E yog dab tsi?
Qhov tsawg kawg nkaus yield zog ntawm SA514 Qib E yog 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. Qhov txawv ntawm SA514 Qib E thiab Qib F yog dab tsi?
Thawj qhov sib txawv yog cov tshuaj muaj pes tsawg leeg. Qib E feem ntau muaj cov qib sib txawv ntawm cov khoom sib txawv (xws li Chromium, Molybdenum, thiab Boron) piv rau Qib F, uas tuaj yeem cuam tshuam rau hardenability, weldability, thiab cov ntawv thov tshwj xeeb, txawm tias ob leeg muaj 100 ksi min yield.
4. Puas yog SA514 Qib E weldable?
Yog, tab sis nrog cov txheej txheem nruj. Nws yuav tsum tau preheating, siv tsawg -hydrogen electrodes, thiab tswj cov cua sov input los tiv thaiv kev tawg thiab tuav txhua yam khoom nyob rau hauv lub tshav kub- cuam tshuam cheeb tsam (HAZ).
5. SA514 Qib E siv rau dab tsi?
Nws yog siv rau hauv cov txheej txheem kev nyuab siab heev rau kev tsim kho hnyav thiab cov khoom siv mining, xws li crane booms, excavator caj npab, thiab thav ntawv qhov twg muaj zog thiab toughness.
6. Cov tshuaj muaj pes tsawg leeg ntawm SA514 Qib E yog dab tsi?
Nws cov ntsiab lus muaj xws li Carbon (~ 0.15-0.21%), Manganese (~ 0.80-1.10%), Silicon (~ 0.40-0.80%), Chromium (~ 0.50-0.80%), Molybdenum (~ 0.18-0.28%), Vanadium (~ 0.08%), thiab 0. (0.0005-0.005%).
7. Lub hardness ntawm SA514 Qib E yog dab tsi?
Brinell hardness ntau yam rau SA514 Qib E yog 235-293 HBW (kwv yees li 22-30 HRC), zoo ib yam li lwm qib zoo li Qib F, vim nws kuj yog ib qho quenched thiab tempered steel.

SA514 Qib Eyogib hom T1 steel. "T1" yog lub npe lag luam keeb kwm rau A514 / SA514 quenched thiab tempered steels. Qib E yog ib qho tshuaj muaj pes tsawg leeg sib txawv raws li tus qauv no.
9. SA514 Qib E puas tuaj yeem raug hluav taws kub?
Yog, nws tuaj yeem raug nplaim taws, tab sis nws yuav tsum tau tswj cov txheej txheem. Preheating ua ntej txiav thiab qeeb, tswj kom txias (feem ntau los ntawm kev siv cov cua sov torches) yog tsim nyog los tiv thaiv kev tsim ntawm nyuaj, tawg - rhiab zones raws ntug txiav.
10. Qhov sib npaug ntawm SA514 Qib E hauv Europe yog dab tsi?
Tsis muaj qhov ncaj, zoo ib 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 los yog S690QL1 (EN 10025-6), txawm tias lawv cov tshuaj muaj pes tsawg leeg sib txawv.
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.
