Cov yam ntxwv ntawm Q355
Ntxiv rau kev ua tau zoo, Q355 muaj cov ntsiab tshwj xeeb uas tiv thaiv cov tshuab hluav taws xob hauv plab corrosion. Vim tias nws yog hlau me me, nws muaj cov ntsiab lus muaj roj carbon qis dua. Yog tias muaj ntau cov pa roj carbon ntau ntxiv rau cov alloy, nws yuav rov faib ua cov hlau cam khwb cia.
Q355 yog qib tshiab Suav hlau uas tau tsim los hloov Q345. Nws cov khoom siv ceev yog 7.85 g / cm3 thiab muaj peb theem zoo, suav nrog Q355B, Q355C, thiab Q355D. Nws muaj cov cuab yeej zoo heev thiab cov txheej txheem kub thiab txias. Hauv qhov sib piv, nws muaj qhov zoo dua thiab txhim kho cov khoom siv kho tshuab thaum piv rau A36 ASTM steel.
Kev siv Q355
Q355 steel muaj cov khoom siv zoo heev, zoo weldability, thiab muaj zog corrosion kuj. Nws tuaj yeem siv los tsim thiab tsim cov roj av cia tso tsheb hlau luam, cov nkoj siab siab, boilers, nkoj, chaw nres tsheb fais fab, thiab ntau lwm yam khoom siv siab. Q355 kuj tau siv dav los ua cov thawv thauj khoom, cov thawv ntim khoom pov tseg, cov thawv ntim huab cua, cov thawv ntim sab nraud, cov thawv ntim khoom, thiab cov thawv ntim khoom.
Yog tias koj xav tau cov hlau uas tsim los sawv ntsug raws li cov kev xav tau ntawm kev tsim kho thiab kev tsim vaj tsev cov khoom uas muab cov weldability zoo thiab toughness, ces Q355 tej zaum yuav yog ib tug muaj zog contender rau koj qhov project tom ntej no los yog txoj hauj lwm.

Q355 steel yog Suav cov qauv hlau, cov khoom ntom ntom: 7.85 g / cm3. Q355B, Q355C, Q355D, khoom, tshuaj muaj pes tsawg leeg yog sib npaug rau European EN.
Qhov kev tso tawm tsis ntev los no ntawm GB/T 1591-2018 tus qauv tshiab tau ua rau muaj kev sib tham ntau heev. Nws puas yuav tsim kev cuam tshuam nrog European tus qauv S355 series? Koj puas xav ua kom cov alloy ntxiv zoo li lub teb chaws tus qauv tshiab rau rebar? Yuav tsis ua rau lwm alloy tig 10 npaug ntawm tus nqi?
Raws li peb txhua tus paub, Tuam Tshoj cov steel kev tsim khoom yog ntau tshaj plaws ntawm cov neeg rebar, ua raws li los ntawm cov phaj steel thiab cov ntawv loj, thiab cov loj tshaj plaws hauv lub phaj yog Q235b, ua raws li Q345B. Qhov cuam tshuam loj tshaj plaws ntawm GB tshiab GB / T 1591-2018 tso yog Q345b, vim tias cov zis ntawm lwm cov qib muaj cov nyhuv me me. Raws li qhov peb tau hais saum toj no, qhov kev hloov no yog nyob rau hauv kab nrog cov qauv thoob ntiaj teb. Nws tuaj yeem qhia los ntawm lub npe lag luam, nws yog qhov tseeb nyob rau hauv kab nrog European txheem. Txawm hais tias nws yog raws ISO, hauv essence, hauv kev lag luam thoob ntiaj teb, S355jr steel phaj tsim kom muaj nuj nqis yog ib yam li Q345B hauv Suav teb.
