W12 {{252 279 A36 / A572GR50 / A992 H BE
ASTM A36 H Nqaj Steel qauv yog cov qauv siv roj carbon hlau tsawg siv hauv kev tsim kho thiab dav dav qauv, nrog rau Weldability zoo thiab ua, tab sis muaj lub zog qis.
ASTM A572 / A572M Qib 50 H tshooj hlau Beam yog qhov zoo dua los ntawm kev ntxiv cov kab hlau (HSLA), uas yog tsim nyog rau cov qauv uas yuav tsum muaj zog dua.
ASTM A992 / A992M H zoo li lub ntsej muag zoo nkauj niaj hnub no, nrog cov khoom siv zoo dua rau North American Tsev Hlau Beams.
Cov yam ntxwv ntawm peb cov ntaub ntawv hauv W12x252 thiab W12X279
A36 H Zoo li cov hlau nqaj
Cov txiaj ntsig: Tus nqi qis, yooj yim rau Weld thiab cov txheej txheem, haum rau cov kev xav tau tsawg.
Cov kev txwv: tsawg tawm lub zog (36 KSI), tej zaum yuav tsum muaj cov ntu loj dua hauv cov qauv hnyav, ua kom yuag thiab tus nqi.
Muaj feem xyuam nrog cov xwm txheej: cov vaj tse me me, Cheeb Tsam.
A572GR50HR50 H-SCRED STEEL LAUM
Cov txiaj ntsig: Ntau dua lub zog (50 Ksi), muaj zog ntawm cov xeeb ceem nyob rau hauv tib seem-seem, haum rau nruab nrab thiab siab thauj.
Cov kev txwv: me dua tus nqi ntau dua A36, qis dua siab me ntsis Weldability tshaj A36.
Muaj feem xyuam nrog cov xwm txheej: Txuas hniav, kev lag luam ntas, nruab nrab ntawm cov vaj tse.
A992 H-SI HOM PHAJ
Cov txiaj ntsig zoo: Muaj kev ua tau zoo tshaj plaws, muaj txiaj ntsig zoo ({} ksi), kev ua seient zoo, dav siv hauv cov tsev niaj hnub no.
Cov kev txwv: tus nqi siab dua li A36 thiab A57GR50.
Muaj feem xyuam nrog cov xwm txheej: Beams loj ntawm cov tsev siab, seismic tsim qauv.
NTA thiab cov ntawv thov ntawm W12X252 W12X279 h hom hlau nqaj
W12252 Khoom siv H nqaj: Lub teeb ci tab sis muaj kev txwv tsis pub loj tab sis yog qhov hnyav-txwv tsis pub dhau cov choj lossis cov tswv cuab theem nrab ntawm cov tuam tsev.
W12X279 Hlau Beam H: hnyav dua, nrog cov khoom siv muaj peev xwm thiab cov nyom ua kom haum rau cov kab teeb ci lossis cov qauv tsim kom muaj kev thauj khoom heev.
Ob qho tib si nyob rau hauv "W12" series, nrog qhov siab ntawm kwv yees li {1}} nti, tab sis tsim nyog rau kev xav tau ntxiv.
