SA514 Qib Fyog lub siab -yield zog, quenched thiab tempered alloy steel phaj paub txog nws lub zog tshwj xeeb (min 100 ksi yield), toughness, thiab weldability zoo, siv nyob rau hauv hnyav-cov ntaub ntawv siv xws li cov khoom siv, tsheb thav duab, thiab crane booms, featuring tshwj xeeb alloying ntsiab rau kev ua tau zoo thiab muaj nyob rau hauv ntau yam thicknesses.
SA514 Qib F thiab "T1" steel (A514) yog tib yam khoom. Qhov no yog ib rooj plaub ntawm cov npe sib txawv rau tib qhov tshwj xeeb, hauv paus hauv kev lag luam keeb kwm thiab kev lag luam.
1. Lub npe tsis meej pem piav qhia
| Lub sij hawm | Nws txhais li cas |
|---|---|
| ASTM A514 Cov Lus Qhia Tshwj Xeeb | Tus txheej txheem ASTM International rau "High-Yield-Strength, Quenched thiab Tempered Alloy Steel Phaj, Haum rau Vuam." |
| ASME SA514 | Tus qauv zoo ib yam, tau txais los ntawm ASME Boiler thiab Pressure Vessel Code. Qhov "S" txhais tau tias nws ua tau raws li ASME cov ntaub ntawv thiab cov ntawv pov thawj. Rau txhua lub hom phiaj siv tau, A514=SA514. |
| Qib F | Ib qho ntawm ntau yam tshuaj muaj pes tsawg leeg (Qib A, B, C, E, F, H, J, K, M, P, Q, R, S) nyob rau hauv A514 / SA514 tus qauv. Qib F yog qib feem ntau thiab siv dav. |
| "T-1 Hlau" | Thawj lub npe lag luam nyob rau hauv uas hom hlau no yog thawj zaug qhia rau kev lag luam los ntawm USS (United States Steel) corporation nyob rau hauv 1950s. Nws tau dhau los ua neeg nyiam heev uas "T-1" feem ntau siv los xa mus rau A514 / SA514 steel, tshwj xeeb tshaj yog Qib F. |
2. Kev sib raug zoo yooj yim
"T-1" yog keeb kwm, lub npe lag luam.
A514 / SA514 yog tus tswj hwm niaj hnub.
Qib F yog qhov tshwj xeeb, feem ntau hom hauv tus qauv ntawd.
Yog li ntawd: "T-1 Steel" ≈ A514/SA514 ≈ Qib F yog cov neeg sawv cev tshaj plaws.
3. Qhov tseem ceeb sib piv & qhia meej
| Yam | Kev sib piv |
|---|---|
| Tshuaj muaj pes tsawg leeg | Zoo tib yam rau tib qib. Yog tias koj xaj "T-1" los ntawm lub zeb niaj hnub no, koj yuav tau txais cov hlau uas ua tau raws li ASTM A514 Qib F chemistry. |
| Mechanical Properties | Ib yam. Yam tsawg kawg nkaus 100 ksi tawm lub zog (rau thickness Tsawg dua los yog sib npaug rau 2.5 in), tib lub zog tensile, elongation, thiab tej yam toughness yuav tsum tau. |
| Kev siv | Ib yam. Siv rau tib daim ntaub ntawv: crane booms, excavator caj npab, hnyav khoom ntas. |
| Kev yuav khoom | Nyob rau hauv niaj hnub specifications, koj yuav tsum hu rau "ASTM A514 Qib F" los yog "ASME SA514 Qib F" rau precision. "T-1" tseem siv sib tham tab sis yog technically vague. |
4. Cov Lus Cim Tseem Ceeb ntawm Lwm Cov Qib
Thaum "T-1" feem ntau txhais tau tias Qib F, tus qauv A514 muaj lwm qib (xws li Qib H, Qib S, thiab lwm yam) nrog cov tshuaj sib txawv me ntsis rau kev txhim kho weldability lossis huab cua tsis kam. Yog tias koj tsuas qhia "T-1," koj yuav tau txais Qib F, tab sis rau kev ua haujlwm tseem ceeb, kev qhia meej A514 Qib yog qhov tseem ceeb.
Kev xaus: Tsis muaj qhov sib piv ntawm SA514 Qib F thiab T1 steel (A514). Lawv yog cov npe sib txawv rau tib lub siab -lub zog quenched thiab tempered alloy steel phaj. SA514/A514 yog tus qauv; Qib F yog qhov txawv txav; "T-1" yog lub npe qub qub uas daig.
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.
