Cov ntsiab lus carbon (c) ntawm SS49 {2}} Tus qauv steel H-} Tus qauv hlau ua hlau feem ntau tsis pub dhau 0.2%, thiab lub zog tensile yog nruab nrab ntawm {}} mpa. Elongation ntawm ss490 hlau nrog ib tuab ntawm tsis muaj ntau tshaj 16 hli yog loj dua lossis sib npaug rau 19%; Qhov elongation ntawm steel nrog ib tuab ntawm ntau dua 16 hli yog loj dua lossis sib npaug rau 15%. SS490 H-puab hlau H-Shaped steel tuaj yeem ua tiav los ntawm kev ua haujlwm kub, ua haujlwm txias, uas yooj yim rau kev tsim kho thiab muaj peev xwm ua lub sijhawm tsim kho.
