Q355B H Section Steel yog dab tsi

Q355B H-Beam yog lub siab- ua haujlwm kub dov cov qauv ntu steel raws li GB/T 1591-2018. Nws symmetrical H-zoo li tus ntoo khaub lig-section muab sib npaug khoov thiab shear kuj piv nrog I-beam, channel steel thiab tiaj phaj. Nws yog qhov nyiam cov neeg siv khoom thauj khoom rau txhua yam ntawm cov txheej txheem steel.

FAQ

01.Dab tsi yog qhov txawv ntawm Q355B H-beam thiab Q235B H-beam?

Q355B muaj lub zog tawm los ntau dua (355MPa vs 235MPa). Nws tuaj yeem nqa cov khoom hnyav dua, haum rau cov chaw tsim khoom loj, txuas hniav thiab hnyav-load steel qauv. Q235B yog rau lub teeb thauj khoom yooj yim thav duab.

02.Puas Q355B H-beam xav tau kev kho cua sov ua ntej kev tsim kho?

Tsis yog. Peb Q355B H-beam yog kub dov thiab ua tau raws li tus qauv siv tshuab ncaj qha tom qab xa khoom. Kev kho cua sov zoo li quenching thiab tempering yog qhov tsis tsim nyog rau kev teeb tsa.

03.Can Q355B H-beam siv nyob rau hauv qis-kub sab nraum tej yaam num?

Q355B muaj qhov kub thiab txias ntawm qhov hnyav (20 degree). Yog tias koj xav tau kev tsim kho nyob rau hauv qhov kub thiab txias, peb tuaj yeem muab Q355C / Q355D qib nrog qis - qhov kub thiab txias tsis kam.

04.Puas yog koj H-beam loj? Koj puas tuaj yeem txiav rau qhov ntev?

nruj me ntsis kam rau ua raws li GB / T 11263 tus qauv. Peb muab kev ruaj khov pub dawb -ntev txiav raws li koj cov duab kos, tsis muaj nqi txiav ntxiv rau kev txiav txim ntau.

05.Yog Q355B yooj yim rau vuam? Kuv puas xav tau cov khoom siv vuam tshwj xeeb?

Q355B muaj weldability zoo heev. Ordinary low alloy welding rods muaj. Preheating tsuas yog yuav tsum tau rau cov seem tuab ntxiv kom tsis txhob vuam tawg.

06.Koj puas tuaj yeem muab cov lus ceeb toom thib peb - tog neeg soj ntsuam ua ntej xa khoom?

Yog lawm. Peb txhawb SGS, BV, TUV thib peb - tog tshuaj xyuas. Txhua batch yog txuas nrog official Hoobkas zeb xeem daim ntawv pov thawj rau kev lis kev cai clearance thiab project txais.
