ASTM A992 Steel Wide Flange H Beam yog ib qho ntawm cov khoom siv dav tshaj plaws siab -lub zog steels rau kev tsim kho niaj hnub no. Nws yog tsim tshwj xeeb rau cov kab flange dav (W-Beams) siv hauv cov tsev, txuas hniav, thiab seismic-cov qauv tiv thaiv.
Piv nrog rau cov qauv siv hlau xws li ASTM A36 lossis ASTM A572 Qib 50, ASTM A992 muaj zog dua, txhim kho weldability, thiab kev ua tau zoo dua seismic. Cov hlau muaj cov micro- alloying cov ntsiab lus xws li vanadium thiab columbium (niobium), uas txhim kho lub zog thaum tuav cov ductility zoo thiab weldability.
ASTM A992 Hlau Dav Flange H Beam
Ib qho txiaj ntsig tseem ceeb ntawm ASTM A992 yog nws cov kev tswj hwm kev ua haujlwm - rau -Tensile zog piv (tsawg dua lossis sib npaug rau 0.85). Cov cuab yeej no ua kom cov hlau tuav tau zoo heev deformation muaj peev xwm ua ntej tsis ua hauj lwm, ua rau nws yog ib qho khoom siv zoo tshaj plaws rau av qeeg-cov qauv tiv thaiv thiab siab- kev ruaj ntseg hauv tsev.
Vim tias cov txiaj ntsig zoo no, ASTM A992 tau hloov pauv ntau A36 thiab A572-50 hauv cov qauv dav dav flange beam thov, tshwj xeeb tshaj yog nyob rau hauv Tebchaws Meskas, Canada, thiab Central & South America.
