SM490 H-puab HW Hm Hn steel
H-nqaj yog muab faib ua kub-dov thiab hom welded. Kub-rolled H-nqaj muaj dav flange h-nqaj (hw), nruab nrab h-nqaj-ci (hm), thiab nqaim H-nqaj (hn).
Qhov siab ntawm HW yog zoo ib yam li qhov dav ntawm cov flange, thiab nws yog tsuas yog siv los ua tus qauv hlau hauv paus hauv cov qauv qauv. Qhov siab-rau-flange dav retth piv rau hm no. 33-1 Lub siab-rau-flange dav ratth piv ntawm HN yog ntau dua lossis sib npaug rau 2, thiab nws yog tsuas yog siv rau cov nqaj.
Cov Khoom Siv Lub Cev
Weldability: nws muaj kev zoo heev weldability thiab tuaj yeem muab tau yooj yim los ntawm ntau txoj kev vuam lug xws li arc vuam kom tau raws li qhov kev xav tau hauv txoj haujlwm.
Kev Tsim Kho Txias: Nws tuaj yeem txiav, khoov, stamped, thiab lwm yam los ntawm kev ua kom txias, thiab yooj yim rau cov txheej txheem thiab tsim ntau yam.
Corrosion Kuj: Corrosion tsis kam ntawm SM490 H-nqaj yog zoo li cov pa roj carbon hlau zoo li qub. Nyob rau hauv ib puag ncig corrosive, tsim nyog los tiv thaiv corrosion yuav coj mus txuas ntxiv lub neej pabcuam.
Cov lus qhia tshwj xeeb thiab qhov ntev
SM490 HW, HM, Hm, H-Beams muaj ntau yam tshwj xeeb. Qhov siab (h) ntawm HW feem ntau 100mm ~ 900mm, thiab cov Flange Dav (B) yog zoo li qhov siab. Qhov siab ntawm HM yog feem ntau 1.33 ~ 1.75 zaug qhov siab ntawm cov flange dav (b). Qhov siab ntawm hn-nqaj kuj muaj los ntawm 100mm rau 900mm, cov vev xaib dav (T2) Qhov ntev yog feem ntau {{{}} m, thiab gnee tuaj yeem kho tau raws li cov kev cai tshwj xeeb.
Qhov Zoo
Siab zog-rau-hnyav piv: SM490 HW, HM, Hma H-Zoo H-Zoo HN H-Zoo HN H-Line zog vim nws tus cwj pwm tsim nyog hla kev. Thaum ris cov nra loj, nws txo qhov kev tsim ntawm cov qauv ntawm cov qauv thiab txhim kho cov kev ruaj khov thiab kev lag luam ntawm cov qauv.
Cov khoom siv zoo: Nws muaj cov tensile zoo, compressive thiab khoov cov zog, thiab tuaj yeem ua kom tau raws li cov kev ua tau zoo ntawm cov tshuab sib txawv.
Kev ua zoo ua tau zoo: tus ntoo khaub lig-seem ntawm kub-shack hald yog tsis tu ncua, uas yooj yim rau kev ua haujlwm thiab tsim khoom, thiab txhim kho kev ua haujlwm zoo.
