Alloys Carbon Steel Q235 Steel Lub kaum sab xis Bar

Alloys carbon steel Q235 steel lub kaum sab xis yog qhov siab -cov qauv kev ua haujlwm tau zoo nrog kev sib xyaw ua ke ntawm cov pa roj carbon monoxide thiab cov kab sib txuas ua ke, tsim los xa cov khoom siv txhim khu kev qha, kev ua haujlwm zoo, thiab tus nqi- ua haujlwm tau zoo rau ntau hom kev lag luam thiab kev tsim kho. Raws li cov khoom siv dav siv cov khoom siv carbon steel, lub kaum sab xis no nruj me ntsis ua raws li Suav teb chaws tus qauv GB / T 700 (Carbon Structural Steels), qhov "Q" qhia tawm lub zog thiab "235" qhia qhov tsawg kawg nkaus yield zog ntawm 235MPa. Tsim los ntawm siab-purity alloys carbon steel billets ntawm mature kub- dov tshuab, nws nta ib classic L-zoo li tus ntoo khaub lig{11}}section (muaj nyob rau hauv vaj huam sib luag-sab thiab tsis sib npaug-sab configurations), ua rau nws ib tug indispensable nyob rau hauv lub indispensable nyob rau hauv ntau yam kev txhawb nqa, scrubs thiab fractional kev lag luam.

Raws li kev tsim qauv, Q235 alloys carbon steel lub kaum sab xis yog tus cwj pwm los ntawm nws lub zog L- zoo li tus tsim, muaj ob txhais ceg (flanges) txuas ntawm qhov tseeb 90-degree txoj cai kaum. Qhov no symmetrical los yog asymmetrical configuration (nyob ntawm seb cov kev xav tau ntawm daim ntawv thov) yog optimized los xyuas kom meej lub cev muaj zog tis, muaj zog tsis kam mus rau dabtsi yog khoov, torsional, thiab shear rog- qhov tseem ceeb ntawm kev ua tau zoo ntawm lub kaum sab xis tuav. Qhov sib npaug -sided variant yog qhov zoo tagnrho rau cov khoom sib luag-cov kabmob xws li lub teeb steel thav duab, phab ntsa girts, ru purlins, thiab handrails, thaum qhov sib npaug ntawm sab sib txawv ua tau zoo hauv kev txhawb nqa asymmetric xws li beam brackets, kem reinforcements, thiab cov khoom siv hauv paus, muab kev sib txawv ntawm cov kev xav tau.

Kev tsim cov alloys carbon steel Q235 lub kaum sab xis tso siab rau cov qib siab kub- dov tshuab, uas yog ib qho tseem ceeb rau kev txhim kho nws cov khoom siv kho tshuab thiab ua kom muaj qhov tseeb qhov tseeb. Alloys carbon steel billets yog thawj zaug rhuab mus rau qhov kub siab tshaj qhov recrystallization point (feem ntau 800-}1050 degree), kev kho cua sov uas softens cov khoom thaum khaws cia cov kev ncaj ncees ntawm nws cov alloy muaj pes tsawg leeg. Cov rhuab billets ces dhau los ntawm precision dov mills kom zoo li tus qauv L-puab, ua raws li ntuj txias rau chav tsev kub. Qhov kub no - dov txheej txheem refines lub sab hauv grain qauv ntawm cov alloys carbon steel, tshem tawm cov tsis xws luag xws li porosity thiab segregation, thiab ua rau ib tug du nto tiav, nruj dimension tolerances, thiab zoo tuab tuab-txhua yam tseem ceeb los xyuas kom meej compatibility nrog rau lwm yam structural Cheebtsam thiab txhim khu kev qha kev ua tau zoo nyob rau hauv daim ntawv thov.

Raws li ib tug neeg sawv cev alloys carbon steel qib, Q235 boasts ib tug zoo - sib npaug tshuaj muaj pes tsawg leeg uas combines cov pa roj carbon thiab trace alloying ntsiab kom ua tau zoo tshaj plaws kev ua tau zoo. Chemically, nws muaj cov ntsiab lus tswj cov pa roj carbon ntau (ntau tshaj 0.22%), manganese (0.35-0.80%), thiab cov lej ntawm silicon, nrog rau kev txwv tsis pub muaj kev puas tsuaj (phosphorus ≤0.045%, sulfur ≤0.045%). Qhov sib ntxiv ntawm cov kab hlau rhuav tshem cov ntsiab lus txhim kho nws qhov toughness, ductility, thiab weldability piv rau cov pa roj carbon zoo tib yam, thaum tswj tus nqi{11}} ua haujlwm tau zoo. Cov tshuaj muaj pes tsawg leeg no ua kom ntseeg tau tias Q235 lub kaum sab xis tuaj yeem ua tiav ntawm qhov chaw yooj yim los ntawm kev txiav, khoov, vuam, thiab drilling yam tsis muaj kev cuam tshuam nws cov qauv kev ncaj ncees, ua rau nws tsim nyog rau ntau yam kev tsim thiab kev tsim kho.

Mechanically, alloys carbon steel Q235 lub kaum sab xis qhia kev txhim khu kev qha thiab zoo ib yam, nrog rau qhov tsawg kawg nkaus lub zog ntawm 235MPa, lub zog tensile ntau ntawm 375-500MPa, thiab qhov tsawg kawg nkaus elongation ntawm 26%. Cov khoom siv kho tshuab no pab kom nws dais lub teeb rau nruab nrab loads tau zoo, ua rau nws haum rau ob qho tib si cov qauv siv thiab kev pabcuam pabcuam. Nws lub hauv paus toughness thiab qaug zog tiv thaiv kom lub sij hawm ntev, txawm tias nyob rau hauv rov qab dynamic loads thiab hnyav ib puag ncig tej yam kev mob, thaum nws zoo weldability tso cai rau kev ruaj ntseg kev twb kev txuas nrog rau lwm yam steel Cheebtsam, tsim ruaj khov thiab txhim khu kev qha cov txheej txheem.
