ASTM A36 S235jr S275jr Ss400 Dav Flange Tus Qauv Welded Carbon Hea / Heb / Ipe Tshooj Kub Rolled Universal Steel H Beams

ASTM A36, S235JR, S275JR, thiab SS400 wide flange structural welded carbon HEA/HEB/IPE seem kub-rolled universal steel H beams yog core structural Cheebtsam tau dav siv nyob rau hauv niaj hnub kev tsim kho thiab engineering tej yaam num, txawv los ntawm lawv cov optimized dav welded qauv { thiab broad compatibility nrog ntau yam qauv siv. Raws li ib qho tseem ceeb ntawm cov qauv steel profile, cov universal H beams integrates qhov zoo ntawm kub- dov ua thiab precision vuam, featuring ib tug standardized "H"-zoo li tus ntoo khaub lig-section muaj li ntawm ob parallel, widened kab rov tav flanges thiab ib tug sturdy 10 lub web sturdy, ntsug. txhim khu kev thauj khoom-cov kabmob muaj peev xwm, thiab ua tiav lub zog zoo- rau- qhov hnyav piv, ua rau lawv qhov kev xaiv tsis tseem ceeb rau siab - kev ua tau zoo steel qauv.

Cov khoom lag luam no suav nrog plaub qib kev lees paub thoob ntiaj teb cov pa roj carbon steel, txhua qhov muaj txiaj ntsig zoo -txhim kho qhov ntsuas thiab ua raws li cov qauv thoob ntiaj teb, ua kom muaj kev hloov pauv mus rau qhov sib txawv ntawm qhov yuav tsum tau ua thiab engineering scenarios. ASTM A36, ib tug dav siv American standard carbon structural steel, boasts ib tug tsawg kawg nkaus yield zog ntawm 250 MPa thiab ib tug tensile lub zog ntawm 400 mus rau 550 MPa, nrog ib tug elongation ntawm tsis tsawg tshaj li 20%. Nws qhov tshwj xeeb ductility, weldability, thiab formability ua rau nws haum rau cov qauv siv, nrog rau lub tsev thav duab, kev cob qhia kev lag luam, txuas hniav, thiab cov qauv kev txhawb nqa, qhov kev ua tau zoo thiab cov nqi siv tau yog qhov tseem ceeb.

S235JR thiab S275JR yog European txheem carbon structural steels adhering rau EN cov qauv, catering rau lub teeb- mus rau - nruab nrab thiab nruab nrab- mus rau - hnyav structural xav tau. S235JR, nrog lub zog tawm los ntawm 235 MPa, nthuav tawm zoo heev weldability, ductility, thiab economic efficiency, ua rau nws zoo tagnrho rau qis-nce vaj tse, modular chaw, auxiliary qauv, thiab lwm yam teeb pom kev zoo{10}} load steel tej yaam num. S275JR, ib nrab - qib European muaj zog, muaj qhov ua tau zoo ntawm 275 MPa thiab txhim kho tensile lub zog, txuas qhov sib txawv ntawm S235JR thiab siab - qib zog. Nws muaj kev thauj khoom zoo tshaj -cov kabmob muaj peev xwm thiab cuam tshuam rau lub zog, haum rau nruab nrab{19}}ntaus vaj tse, kev lag luam cov qauv, thiab cov haujlwm engineering uas xav tau cov qauv kev ruaj ntseg dua.

SS400, Japanese JIS tus qauv carbon steel, muab kev sib xyaw ua ke ntawm lub zog thiab kev lag luam, nrog lub zog tawm los ntawm kwv yees li 245 MPa thiab lub zog tensile xws li 400 txog 510 MPa. Nws cov khoom ruaj khov thiab kev sib txuas zoo ua rau nws siv dav hauv Asian tsim cov haujlwm, suav nrog cov tsev nyob, cov chaw tsim khoom, thiab kev tsim vaj tsev, qhov twg tus nqi -kev ua tau zoo thiab kev ua tau zoo yog qhov tseem ceeb rau kev txiav txim siab.

Tag nrho cov H beams no yog tsim los ntawm kev kub siab - dov thiab precision vuam txheej txheem, kom ntseeg tau tias zoo ib yam thiab cov qauv kev ncaj ncees. Cov txheej txheem kub - dov refines steel grain qauv, txo qhov seem ntawm cov kev ntxhov siab, thiab txhim kho qhov tseeb qhov tseeb thiab nto zoo, thaum lub vuam txheej txheem txhim kho kev sib txuas ntawm flanges thiab lub vev xaib, kom ntseeg tau tias muaj kev sib kis sib kis thiab ntev - lub sij hawm kev ruaj ntseg. Cov khoom lag luam npog peb qhov tseem ceeb European universal seem series: HEA (European wide flange beams nrog nqaim flanges), HEB (European wide flange beams nrog thicker, wider flanges rau siab load peev), thiab IPE (European I-beams nrog optimized web thiab flange dimensions), tag nrho cov featuring loj {6} diversified auxiliary thav duab mus rau loj - ncua kev lag luam vaj tse thiab siab - sawv cev.

Qhov dav -flange tsim ntawm cov H beams no muaj qhov zoo sib xws hauv kev siv cov qauv: cov flanges dav dav ua rau ntu ntu lub sijhawm ntawm inertia thiab torsional nruj, zoo tiv thaiv dabtsi yog khoov thiab shear rog, thaum tseem ua kom yooj yim kev sib txuas thiab kev teeb tsa. Lawv cov weldability zoo heev thiab cov txheej txheem ua tau zoo tso cai rau kev sib dhos zoo los yog welded nrog rau lwm yam khoom siv (xws li txhua kab, braces, thiab purlins), txhim kho qhov zoo ntawm - qhov chaw tsim kho kom zoo thiab txo cov nqi zog. Tsis tas li ntawd, cov khoom siv carbon steel yog ib puag ncig tus phooj ywg thiab rov ua dua tshiab, ua raws li cov tswv yim tsim kho kom ruaj khov thiab txo qhov cuam tshuam ib puag ncig ntawm engineering tej yaam num.

Tag nrho cov khoom lag luam raug tswj xyuas kom zoo thiab cov txheej txheem tshuaj xyuas raws li cov txheej txheem thoob ntiaj teb (ASTM, EN, JIS, thiab lwm yam), suav nrog kev tshuaj xyuas tshuaj lom neeg, kev ntsuas kev ua haujlwm (tensile, cuam tshuam, dabtsi yog khoov), weld zoo soj ntsuam, thiab qhov tseeb qhov tseeb. Qhov no ua kom ntseeg tau tias txhua pawg ntawm H beams ua tau raws li cov kev cai nruj ntawm kev tsim vaj tsev, lav kev nyab xeeb thiab kev ntseeg siab hauv kev ua haujlwm ntev -. Tsis tas li ntawd, cov kab teeb tuaj yeem hloov kho raws li qhov tshwj xeeb, qhov ntev, thiab kev kho saum npoo (xws li kub-dip galvanizing, tiv thaiv- pleev xim rau xim) kom haum rau cov xwm txheej tshwj xeeb, txuas ntxiv nthuav dav lawv daim ntawv thov nyob rau hauv ntau yam steel qauv teb.

Hauv cov ntsiab lus, ASTM A36, S235JR, S275JR, thiab SS400 wide flange structural welded carbon HEA/HEB/IPE seem kub-rolled universal steel H beams integrate standardization, siab zog, weldability, thiab versatility. Lawv muab qhov ruaj khov, ua tau zoo, thiab tus nqi- cov qauv tsim kho tau zoo rau cov phiaj xwm kev tsim kho thoob ntiaj teb, ua lub luag haujlwm tseem ceeb hauv kev txhim kho cov qauv hlau niaj hnub thiab kev txhawb nqa kev tsim kho vaj tse ruaj ntseg, ruaj khov, thiab ruaj khov.
