Muaj & Cov Qauv

Kev tswj hwm los ntawm ASTM A514 / ASME SA514 specifications, nrog Qib F yog ib qho ntawm ntau txoj kev xaiv.

Muab raws li daim hlau, feem ntau nyob rau hauv thicknesses los ntawm ib ncig ntawm 0.185 "mus txog 2.5" (los yog ntau tshaj nyob ntawm thickness), nrog rau dav thiab ntev qhov ntev muaj.

Cov tshuaj muaj pes tsawg leeg ntawm Kev Ntsuas Kub rau SA514 Qib F quenched thiab tempered steel phaj (Max%)

Qhov tsawg kawg nkaus yield zog ntawm SA514 Qib F steel yog 100 ksi (690 MPa) rau cov khoom mus txog 2.5 nti (63.5 hli) nyob rau hauv thickness.

Txawm li cas los xij, zoo li feem ntau siab - lub zog steels, nws tau lees tias qhov tsawg kawg nkaus lub zog tawm los txo qis raws li cov phaj thickness nce vim lub physics ntawm kev kho cua sov thaum lub sij hawm tsim khoom.

Ntawm no yog cov kev xav tau ntawm lub zog tshwj xeeb raws li ASTM A514 / SA514 tus qauv:

Yield Strength (yam tsawg kawg) los ntawm Thickness - SA514 Qib F

(Faj seeb: Qee cov qauv tsim los ntawm cov mills loj tuaj yeem tswj tau lub zog ntau dua ntawm cov thickness ntau dua.)

Cov Khoom Siv Hluav Taws Xob Tseem Ceeb (rau thickness Tsawg dua lossis sib npaug rau 2.5 hauv / 63.5 hli):

Tensile zog: 115 - 135 ksi (790 - 930 MPa)

Elongation (hauv 2 hauv / 50 mm): 18% yam tsawg kawg nkaus

Hardness (Hnub): 235 - 293 HBW (kwv yees . 22-30 HRC)

Impact Toughness: Charpy V-nqaj qhov yuav tsum tau muaj feem ntau tau teev tseg (piv txwv li, 40-50 ft-lbf ntawm -50℃F / 54-68 J ntawm -45℃), kom ntseeg tau tias kev puas tsuaj zoo heev.

Cov Lus Qhia Tseem Ceeb:

Cov kws tsim khoom yuav tsum siv cov txiaj ntsig lub zog muaj txiaj ntsig sib xws rau qhov tseeb tuab ntawm cov phaj hauv lawv cov qauv tsim. Piv txwv tias 100 ksi tawm los rau 5-inch tuab phaj yuav tsis muaj kev saib xyuas thiab tsis zoo. Tus nqi raug rau qhov tuab yuav yog 85 ksi (585 MPa).

Nyob rau hauv cov ntsiab lus, thaum SA514 Qib F yog nto moo rau nws 100 ksi yield zog, tus nqi no tsuas yog guaranteed rau daim hlau mus txog 2.5 nti tuab. Rau cov seem thicker, qhov tsawg kawg nkaus yield zog yog nce zuj zus, raws li qhia nyob rau hauv cov lus saum toj no.

Hu rau tam sim no

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?
