Khoom Description
Ua ntej, cov khoom siv ntawm H-beam Q355 feem ntau yog qis- alloy siab- lub zog cov qauv hlau. Lub npe "Q355" yog qhov taw qhia tseem ceeb, sawv cev rau lub zog tawm los ntawm 355 MPa. Tshwj xeeb, thaum cov hlau raug rau sab nraud, nws lub zog tawm los mus txog 355 MPa.
Cov hlau lub zog tensile, elongation, thiab cuam tshuam toughness kuj zoo dua li cov pa roj carbon zoo tib yam steel, ua rau nws siv dav hauv cov qauv uas xav tau lub zog siab thiab zoo plasticity.
Qhov qis- alloy muaj pes tsawg leeg ntawm H-beam Q355 feem ntau suav nrog carbon, silicon, manganese, phosphorus, thiab sulfur, nrog rau me me ntawm alloying ntsiab xws li vanadium, titanium, thiab niobium.
Qhov sib ntxiv ntawm cov alloying ntsiab lus no tsis tsuas yog txhim kho lub zog ntawm cov hlau, tab sis kuj txhim kho nws cov toughness, weldability, thiab corrosion kuj. Los ntawm kev tswj cov hom thiab cov ntsiab lus ntawm alloying cov ntsiab lus, H-beams tuaj yeem tsim kom tau raws li cov kev xav tau sib txawv.
Hais txog kev siv tshuab ntau lawm, H-beam Q355 feem ntau yog tsim los siv cov tshuab kub dov txoj kev. Cov txheej txheem no suav nrog cua sov cov hlau mus rau qhov ntsuas kub thiab tom qab ntawd dov nws kom ua tiav qhov kev xav tau ntawm tus ntoo khaub lig-sectional shape thiab dimensional precision.
Kub-khoov H- kab teeb muaj cov yam ntxwv ntawm qhov zoo ntawm qhov chaw zoo, qhov loj me, lub zog siab, thiab yooj yim ntawm vuam, uas yog vim li cas lawv tau siv dav hauv kev tsim kho, txuas hniav, thiab lwm yam.
Ntxiv nrog rau nws cov khoom siv thiab cov txheej txheem tsim khoom, H-beam Q355 kuj muaj qhov zoo tshaj plaws weldability. Qhov no yog vim nws qhov qis- alloy muaj pes tsawg leeg thiab tsim nyog cov pa roj carbon sib npaug. Hauv kev siv tshuab ua haujlwm, H-beam Q355 tuaj yeem txuas nrog siv ntau txoj kev vuam, xws li phau ntawv arc vuam, submerged arc vuam, thiab roj-shielded vuam. Nws cov pob qij txha welded kuj pom muaj lub zog siab thiab zoo toughness, ua kom muaj kev nyab xeeb thiab ruaj khov ntawm cov qauv.
Ntxiv mus, H-beam Q355 muaj kev tiv thaiv corrosion zoo, ua tsaug rau kev tswj xyuas zoo ntawm cov ntsiab lus xws li phosphorus thiab sulfur hauv nws qis- alloy muaj pes tsawg leeg, nrog rau cov txheej txheem kho cua sov tsim nyog. Hauv cov ntawv thov siv tau, H-beam Q355 tuaj yeem siv tau ntev hauv qee qhov chaw corrosive yam tsis tas yuav muaj kev tiv thaiv ntxiv.
