ASTM A514 Qib T steel phaj

ASTM A514 feem ntau yog siv los ua cov qauv hlau hauv cranes thiab cov tshuab hnyav hnyav.

A514 yog hom tshwj xeeb ntawm cov hlau muaj zog, uas yog quenched thiab tempered alloy steel, nrog lub zog tawm ntawm 100,000 psi (100 ksi lossis kwv yees li 700 MPa). Lub npe ArcelorMittal yog T-1. A514 feem ntau yog siv los ua cov qauv hlau rau kev tsim kho lub tsev. A517 yog ib qho zoo sib xws alloy uas yog siv rau kev tsim cov hlab ntsha siab.

Qhov no yog tus qauv tsim los ntawm lub koom haum tus qauv ASTM International, lub koom haum tsim kho cov qauv kev ua haujlwm uas tsim cov qauv kev qhia rau cov khoom siv, cov khoom, cov tshuab, thiab cov kev pabcuam.

A514
Lub zog tensile lub zog ntawm A514 alloys tau teev tseg tsawg kawg yog 100 ksi (689 MPa) rau thicknesses txog 2.5 ntiv tes (63.5 hli) tuab phaj, thiab tsawg kawg yog 110 ksi (758 MPa) qhov kawg tensile lub zog, nrog rau ib qho kev qhia qhov kawg ntawm 110-130 ksi (758-896 MPa). Daim phiaj los ntawm 2.5 mus rau 6.0 ntiv tes (63.5 mus rau 152.4 mm) tuab tau teev lub zog ntawm 90 ksi (621 MPa) (yield) thiab 100–130 ksi (689–896 MPa) (qhov kawg).

A517
A517 steel muaj qhov sib npaug tensile tawm lub zog, tab sis me ntsis siab dua qhov kawg lub zog ntawm 115-135 ksi (793-931 MPa) rau thicknesses txog 2.5 ntiv tes (63.5 hli) thiab 105-135 ksi (724-931 MPa) rau thicknesses 2.5 rau 6.0 nti (63.5 txog 152.4 mm).

Kev siv
A514 steels yog siv nyob rau hauv qhov chaw weldable, machinable, siab zog steel yuav tsum tau kom txuag tau qhov hnyav los yog ua tau raws li qhov kawg ntawm lub zog. Nws feem ntau yog siv los ua cov qauv hlau hauv kev tsim vaj tsev, cranes, lossis lwm lub tshuab loj uas txhawb nqa siab.

Tsis tas li ntawd, A514 steels tau teev tseg los ntawm cov qauv tub rog (ETL 18-11) siv los ua cov riam phom me me baffles thiab cov phaj deflector.
