Cov Nta Tseem Ceeb
Lub zog siab - rau - qhov hnyav} qhov hnyav. Piv: Zoo tagnrho rau lub teeb yuag tam sim no tsis tau ruaj khov qauv.
Weldability:Yuav tsum tau kom preheating (150-230℃/ {{{4 4}} Weld Kev Kho Mob Kub (PWHT) kom tsis txhob tawg.
Taus:Zoo heev cuam tshuam ntawm tsawg kub.
Qeeb zog tsis kam: Haum rau Cyclic Chaw thau cov ntawv thov.
Machinability:Nruab Nrab (yuav tsum tau cov cuab yeej carbide vim muaj kev nyuaj siab).
Cov Ntawv Thov
Txheej txheem engineering:Cov Cheebtsam Choj, crane booms, thiab siab-} NCO SIV LUB NPE.
Cov cuab yeej hnyav:Excavator caj npab, tsheb nrau av hniav, thiab tsuas Machinery.
Tsheb thauj mus los:Tsheb thav duab, trailer chassis, thiab cov tsheb ciav hlau.
Ua Tub Rog / Aerospace:Cov cuab yeej tsheb tsheb thiab thauj khoom - cov kabmob qauv.
Roj & Roj:Offshore platforms thiab cov khoom siv drilling.
Sau ntawv cia
Kev Kho Cua Sov:Quenched thiab tempered (Q & T) kom tau txais lub zog zoo thiab tawv.
Qhov tuab:Muaj nyob rau hauv daim hlau mus txog 6.5 nti (165 mm), tab sis cov tuab tuab yuav tau kho cov kev kho cua sov.
Corrosion Kuj:Tsis muaj inherently corrosion - tsis kam; Yuav tsum muaj cov txheej txheej (piv txwv li, galvanizing siv sab nraum zoov.
Piv rau lwm qib
- ASTM A572 Qib 50: Txo lub zog (345 mpa yield) tab sis pheej yig dua rau tsis {{tus qauv tseem ceeb.
- ASTM A36: Cov hlau me me uas muaj lub zog qis (250 MPa tawm los) tab sis zoo dua machinity.
- ASTM A517 (Qib B): Lub Zog Loj (760 MPa tawm tswv yim) tab sis kim dua, siv rau hauv cov hlab ntsha siab.
Vim li cas thiaj xaiv A544 qib b?
Nws cov sib npaug siab, weldability, thiab tawv, ua rau nws zoo tagnrho rau kev siv cov txheej txheem ncaj ncees hauv qab lossis chaw hnyav. Yuav tsum sab laj ASTM A514 cov lus qhia tshwj xeeb rau cov phiaj xwm - kev cai.

Cov FAQ
Q: Dab tsi yog ASTM A514 qib b?
A: ASTM A514 Qib B yog qhov quenched thiab tempered alloy steel phaj rau cov ntawv thov muaj kev tsim muaj zog ua ke nrog kev ua kom zoo thiab tawv. A544 Qib B muaj qhov tsawg kawg los lub zog ntawm 100 ksi [690 MPA] thiab tej zaum yuav tau them nyiaj ntxiv rau cov nqi ntxiv.
Q: Dab tsi yog A514 qib sib npaug?
A: Lwm cov kev tsim qauv uas sib npaug rau AISI A514 Qib F Alloy Steel suav nrog cov hauv qab no: ANTM A514 (F) ATTM A517 (F)
