A709 H Nqaj Tsim
Dab tsi yog A709 H-hom Steel?
A709 H-hom hlau hais txog H-puab cov txheej txheem hlau nqaj hlau (tseem hu ua H-Beams lossis dav-flange beed Qhov "H-hom kev tsim kho nws cov kab ntawv hla, zoo li tus tsiaj ntawv" H, "uas muab cov khoom muaj peev xwm zoo tshaj plaws thiab cov qauv ruaj khov.
Cov hlau no muaj nyob hauv ntau qib kawm, xws li qib 36, Qib 50W, HPS 50W, txhua qhov kev txiav txim siab rau lub zog thiab ib puag ncig xav tau. Qhov "W" nyob rau hauv qee qib sawv rau "Weathering," qhia tau cov khoom siv hlau ua kom zoo, thaum "HPS" ntawm Weldility thiab Toforness.
Cov qib ntawm A709 H-hom hlau
A709 H-hom steel los hauv ob peb qib, txhua tus nrog cov khoom sib txawv thiab cov ntawv thov. Hauv qab no yog ib qho kev qhia txog ntawm cov qib feem ntau:
1. A709 Qib 36
Peple Zog: 36 Ksi (250 MPa)
Cov ntawv thov: siv nyob rau hauv cov haujlwm xav tau tsawg dua uas muaj lub zog muaj zog yog qhov txaus.
Cov yam ntxwv: Them nqi zoo thiab yooj yim rau Weld.
2. A709 Qib 50
Peple Zog: 50 Ksi (345 MPa)
Cov ntawv thov: nquag nyob hauv kev tsim kho choj thiab cov qauv kev coj ua dav dav.
Cov yam ntxwv: cov sib npaug muaj zog thiab pheej yig.
3. A709 Qib 50W
Peple Zog: 50 Ksi (345 MPa)
Cov ntawv thov: zoo tagnrho rau cov qauv sab nraum zoov raug rau huab cua, xws li txuas hniav thiab yees.
Cov yam ntxwv: txhim kho corrosion tsis kam vim ntxiv cov alloying cov ntsiab xws li tooj liab thiab chromium.
4. A709 HPS Qib (HPS 50W, HPS 70W, HPS 100W)
Paib lub zog:
HPS 50W: 50 Ksi (345 MPa)
HPS 70W: 70 KSI (485 MPa)
HPS 100W: 100 KSI (690 MPA)
Cov Ntawv Thov:High-kev ua tau zoo txuas hniav thiab cov cuab yeej tseem ceeb ntawm cov phiaj xwm.
Cov yam ntxwv:Superior Tougness, Weldability, thiab tsis kam tawm tsam rau brittle bacacture, txawm tias nyob rau hauv huab cua.
Cov qhab nia kawm tau raug sim rau lub zog tensile, tshem tawm lub zog, thiab kev cuam tshuam tsis kam (ntawm Charpy V-Ceebtaws kev sim siab), kom muaj kev ntseeg tau nyob hauv cov chaw xav tau.
Tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv neeg kho tshuab
Lub zog tensile: ranges los ntawm 58 ksi (qib 36) rau tshaj 110 ksi (HPS 100W).
Kev Txiaj Ntsig: Feem ntau 18-21%, kom nruj dua rau cov qauv hloov pauv.
Kev Cuam Tshuam: Yuav tsum muaj kev xeem them nqi rau pob txha lov-tseem ceeb, tshwj xeeb tshaj yog nyob rau hauv huab cua txias.
