SM490 H-Beam tshooj khoom
SM490 H Beam cov khoom yog lub siab-zog qauv txheej txheem txhais tau los ntawm Japanese muaj kev tsim kho thiab siv dav hauv kev tsim kho, kev siv hluav taws xob thiab cov khoom siv hnyav thiab cov khoom siv hnyav.
SM490 hect hlau muaj cov khoom siv zoo dua piv rau cov neeg qib qis xws li SS400, ua rau nws haum rau cov ntawv thov tsim qauv.
Txhawm rau txhim kho corrosion tsis kam thiab txuas ntxiv lub neej pabcuam, SM490 h Tshooj Hlau Beam muab los ntawm GNEE-DIP galvanizing, pleev xim thiab hmoov txheej.
Cov Cuab Yeej Siv Cov Neeg Kho Tshuab ntawm SM490 H Ntu Beam
Lub zog tensile: 490-610 mpa
Paib lub zog: ntau dua los yog sib npaug rau 325 MPa
Elongation: ntau dua los yog sib npaug rau 21% (tuab tsawg dua lossis sib npaug rau 16 hli)
Hardness: Feem ntau nyob ib ncig ntawm 140 HB (Brinell Hardness)
Cov khoom no ua rau SM490 zoo tagnrho rau cov ntawv thov uas xav tau cov khoom muaj peev xwm siab thiab kev tawm tsam zoo rau kev ntxhov siab.
SM490 hect hlau yog tsim los ntawm kub dov lossis vuam cov txheej txheem los xyuas kom muaj kev sib dhos, lub zog thiab qhov raug. Nws muaj lub zog siab thiab lub zog thiab siv dav hauv ntau yam kev lag luam. Cov ntawv thov uas muaj xws li cov cuab yeej siv hauv kev tsim kho ntawm kev tsim kho, cov cuab yeej siv hluav taws xob, cov tshuab hnyav, thiab cov txheej txheem tawm tsam.
