Q235B Q345b Q420c Q460c Ss400 thiab lwm yam 250X250 H Beam

Peb 250X250 H kab teeb, muaj nyob rau hauv ntau yam ntawm cov qib zoo steel xws li Q235B, Q345B, Q420C, Q460C, thiab Ss400, yog siab -cov qauv kev ua tau zoo ntawm cov khoom siv tau zoo heev rau kev tsim kho ntau yam. Raws li cov txheej txheem steel cov khoom lag luam, cov H beams sib xyaw ua ke cov khoom siv kho kom haum ntawm ntau qib steel nrog rau qhov ruaj khov -qhov kom zoo dua ntawm 250X250 profile, xa cov khoom siv txhim khu kev qha-cov kabmob muaj peev xwm, muaj peev xwm siv tau ntau yam, thiab zoo ib yam kom tau raws li qhov xav tau ntawm kev tsim vaj tsev niaj hnub thiab niaj hnub engineering.

Nyob rau hauv cov nqe lus ntawm cov khoom tseem ceeb, txhua qib steel nyob rau hauv cov khoom kab no muaj qhov zoo ntawm kev ua tau zoo, catering rau txawv load thiab ib puag ncig yuav tsum tau. Q235B, siv dav siv me me carbon steel qib, nta qhov tsawg kawg nkaus lub zog ntawm 235 MPa, zoo heev ductility, thiab superior weldability. Nws txoj kev tsim tau zoo ua rau cov txheej txheem tsim khoom yooj yim xws li txiav, khoov, thiab drilling, ua rau nws zoo tagnrho rau cov xwm txheej kev tsim kho uas xav tau tus nqi- ua tau zoo thiab yooj yim ntawm kev teeb tsa. Q345B, siab -lub zog qis- alloy steel, elevates kev ua tau zoo nrog qhov tsawg kawg nkaus yield zog ntawm 345 MPa, ntsuas ductility thiab load{10}}cov kabmob muaj peev xwm, haum rau nruab nrab mus rau hnyav-cov haujlwm ua haujlwm nyob rau hauv siab - nce thiab cov nroj tsuag muaj kev lag luam.

Rau qhov xav tau ntau dua -cov haujlwm ua haujlwm, Q420C thiab Q460C sawv cev rau qib siab- lub zog steel nrog qhov tsawg kawg nkaus qhov muaj zog ntawm 420 MPa thiab 460 MPa feem. Cov qib no nthuav tawm qhov tshwj xeeb tawv, qaug zog, thiab kev cuam tshuam (kuaj ntawm 0℃rau Q420C thiab -20℃rau Q460C), ua kom muaj kev ncaj ncees nyob rau hauv qhov hnyav hnyav thiab hnyav ib puag ncig, xws li loj -span txuas hniav, hnyav kev lag luam rhiav, 7} lub tsev siab siab -}cov choj loj, cov chaw ua haujlwm hnyav 7}. Ss400, Japanese standard carbon steel qib, boasts txhim khu kev qha tensile zog thiab toughness, nrog ib tug tsawg kawg nkaus yield zog ntawm 235 MPa (rau thickness tsawg dua los yog sib npaug zos rau 16 hli), ua raws li tus nqi-zoo thiab ntau yam kev xaiv rau cov qauv siv thoob ntiaj teb.

Raws li tus qauv, qhov ruaj khov 250X250 cross-sectional dimension ntawm H beams no yog tsim los rau kev ua tau zoo thiab kev ua qauv zoo. Qhov profile nta ob qhov sib npaug ntawm flanges (250mm hauv qhov dav) txuas los ntawm lub vev xaib hauv nruab nrab, kom ntseeg tau tias muaj kev faib tawm ntawm lub sijhawm khoov, compressive rog, thiab shear loads. Lub 250X250规格 ntaus ib qho kev sib npaug ntawm seem modulus thiab qhov hnyav, endowing lub nqaj nrog lub zog zoo - rau - qhov hnyav piv. Qhov kev tsim no tso cai rau kev sib kis tau zoo-flanges tiv thaiv kev khoov thiab sab nraub qaum, thaum lub vev xaib tau txais txiaj ntsig zoo tshaj tawm cov kev ntxhov siab- ua rau cov nqaj tsim nyog siv los ua cov kab teeb tseem ceeb, kab, lossis cov tswv cuab hauv ntau yam qauv. Tsis tas li ntawd, tus qauv 250X250 qhov ntev ua kom zoo ib yam ntawm qhov raug thiab sib raug zoo nrog lwm yam khoom siv, ua kom yooj yim rau kev tsim kho thiab txhim kho qhov project efficiency.

Hauv kev tsim kho, 250X250 H kab teeb nrog ntau qib steel tau siv dav hauv ntau qhov haujlwm. Q235B thiab Ss400 qib feem ntau ua haujlwm nyob rau hauv qhov chaw siab -nce, chaw ua haujlwm, thiab me me mus rau nruab nrab- loj ua lag luam complexes. Q345B yog qhov zoo dua rau kev lag luam warehouses, chaw ntau pob, thiab cov chaw thauj mus los uas yuav tsum tau ua kom muaj peev xwm ua tau zoo dua -cov kabmob muaj peev xwm. Q420C thiab Q460C qib ua tau zoo hauv cov phiaj xwm tseem ceeb xws li loj- txuas txuas, cov nroj tsuag hnyav, thiab siab - nce lub tsev cores. Tag nrho cov H beams no tau sib xws nrog ntau yam kev tiv thaiv saum npoo (xws li, tiv thaiv- pleev xim rau corrosion, galvanization), txhim kho lawv cov av noo, oxidation, thiab muaj corrosion, yog li txuas lawv lub neej kev pab cuam nyob rau hauv ntau yam huab cua thiab ua hauj lwm tej yam kev mob.

Ua kom tiav, peb 250X250 H kab teeb, muaj nyob rau hauv Q235B, Q345B, Q420C, Q460C, Ss400, thiab lwm qib, sawv cev rau ntau yam thiab txhim khu kev qha kev daws teeb meem rau kev tsim kho niaj hnub. Kev sib xyaw ua ke ntawm cov khoom siv kho kom haum ntawm ntau qib qib zoo steel nrog qhov ua tau zoo 250X250 tus ntoo khaub lig-sectional tsim, lawv ua tau raws li cov kev xav tau sib txawv ntawm kev dav dav, nruab nrab{11}}lub luag haujlwm, thiab hnyav- lub luag haujlwm tsim kho. Kev ntseeg siab los ntawm cov kws tsim qauv tsim qauv, kws tsim vaj tsev, thiab cov kws tsim kho thoob ntiaj teb, cov H beams no muab cov khoom zoo ib yam, kev ua tau zoo dua, thiab tus nqi- ua tau zoo, ua rau lawv yog qhov kev xaiv tseem ceeb hauv kev tsim kho thoob ntiaj teb.
