Hauv cov lus yooj yooj yim, thaum koj pom "Astm 519 4130 {}} molybdenum cov khoom lag luam ntawm cov khoom ntiag tug ntawm A519 tus qauv.
1. Cov yam ntxwv tseem ceeb ntawm SAE / AISI 4130 tus hlau
Cov khoom nws tus kheej, 4130, piav txog nws cov tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv tau.
Lub Npe:Chromoly Steel (chrome - moly)
Tshuaj lom neeg muaj pes tsawg leeg (ib txwm):
Cov pa roj carbon (c):0.28-0.33% (muab lub zog thiab cov tawv tawv)
Chromium (CR):0.80-1.10% (nce zog, corrosion tsis kam, thiab lub zog ntawm kev kub siab)
Molybdenum (MO):0.15-0.25% (txhim kho kom muaj zog thaum muaj qhov kub thiab txias dua)
Cov yam ntxwv tseem ceeb:
Siab zog - rau - qhov hnyav. Piv:Muaj zog dua cov hlau me (piv txwv li, ASTM A513) yam uas tsis muaj lub cev yuag tseem ceeb.
Dev zoo thiab tawv tawv:Tuaj yeem tsim thiab machined kuj zoo nyob rau hauv ib txwm lossis anealed mob.
Zoo heev Weldability:Welds zoo nrog cov txheej txheem tsim nyog (Pre6- cua sov thiab tshaj tawm kev kho cua sov feem ntau pom zoo, tshwj xeeb tshaj yog rau cov tuab tuab).
Teb zoo rau kev kho cua sov:Nws cov cuab yeej tuaj yeem ua kom pom tseeb los ntawm cov txheej txheem xws li quenching thiab tempering kom ua tiav lub zog, kev nyuaj, thiab qib nyuaj.
2. Xav tau ntawm Astm A519 Txuj Ci
A519 tus qauv qhia tawm cov cai uas ua tiav ntawm lub raj uas tau ua tiav, feem ntau tsom rauCov Khoom Siv Neeg Kho TshuabCov. Lub ntsiab lus tseem ceeb yog tias A519 yog aCov Cuab Yeej Cuab Yeej Cuab Yeejspec, tsis yog tsuas yog tshuaj lom neeg xwb.
Cov khoom uas xav tau sib txawv raws li lubYam tseem ceeb(Kev kho cua sov) ntawm lub raj. Feem ntau cov xwm txheej yog:
| Yam tseem ceeb | Kev piav txog | Cov cuab yeej ua haujlwm ntse (tsawg kawg nkaus) rau 4130 |
|---|---|---|
| Qib 1020 (rau kev sib piv) | Txias tiav, annealed | TENILILE: 70 KSI (483 MPa) Tawm los: 50 Ksi (345 MPa) |

| 4130 -} li qub | Rhuab thiab huab cua -} txias rau kev sib xyaw | TENILILE: 80 Ksi (552 MPa) Tawm los: 50 Ksi (345 MPa) |
| 4130 -} omonized & tempered | Qub, ces tempered rau lub zog / kev sib npaug sib npaug | Tensile: 90 ksi (621 MPa) tawm los: 60 ksi (414 mpa) |
| {{0 {}} Quenched & Tempered | Rhuab, quenched, thiab tempered rau lub zog siab tshaj plaws | TENILILE: 95-110 KSI (655-758 MPa) Tawm los: 75-85 KSI (517-586 MPA) |
Lwm yam A519:
Qhov loj me:Npog sab nraud ntawm lub cheeb (OD) thiab phab ntsa tuab (wt) thev taus.
Zoo Tshaj:Lub raj raj yuav tsum yog kev lag luam du thiab pub dawb uas yuav muaj kev phom sij rau nws cov ntawv thov.
Nondestructive Testing (NDT):Thaum tsis tas yuav tsum tau ua, eddy tam sim no lossis ultrasonic kuaj tuaj yeem hais kom ntseeg tau sab hauv thiab sab nraud.
3. Cov Ntawv Thov Tib Neeg
ASTM A 519 4130} Kev Seamless Tubing yog xaiv rau cov ntawv thov kom muaj zog, thiab lub zog zoo} {2} Qhov hnyav} qhov hnyav.
Aerospace:Cov kab hydraulic, cov qauv txheej txheem, tsaws iav qhov chaw.
Automotive & Sib tw:Yob tawb, lub voos hau, tsav tsheb, tsav cov ntaub ntawv, tshem tawm qhov chaw.
Roj & Roj:Cov cuab yeej downhole, cov tubing lub tubing, hydraulic kheej kheej kheej.
Machinery:Siab - Lub Siab Thooj Voos Kheej, Piston Rods, Cov Kab Tsho, Thiab Lwm Yam Siab} Kev ntxhov siab ntau yam.
4. Kev sib piv nrog lwm tus qauv
Nws yog ib qho tseem ceeb kom paub qhov txawv A519 los ntawm lwm cov qauv uas tseem them rau 4130 hlau.
| Lub hom phiaj | Lub npe | Qhov tseem ceeb sib txawv |
|---|---|---|
