Q: Cov khoom ntawm DC04 kauj yog dab tsi?
A: Nws yog qis- carbon txias- dov steel kauj rau kev sib sib zog nqus nqus, ua raws li GB / T 5213-2019 (raws li EN 10130). Nws cov yam ntxwv tseem ceeb yog cov ntsiab lus tsis tshua muaj carbon thiab siab formability, siv rau complex txias stamping.
Q: Cov cim tseem ceeb ntawm cov tshuaj muaj pes tsawg leeg ntawm DC04 yog dab tsi?
A: C≤0.08%, Mn≤0.4%, P≤0.025%, S≤0.02%, Al≥0.015%, thiab cov khoom seem seem ua tau raws li tus qauv txwv.
Q: Dab tsi yog qhov txawv ntawm DC04 thiab SPCC, SPCD, thiab SPCE?
A: DC04 muaj superior formability: r90≥2.0, n90≥0.20, thiab elongation ≥40%; SPCC yog rau kev siv dav dav, thiab SPCD/SPCE muaj qis dua - kos duab zoo dua DC04.
Q: Dab tsi yog qhov kev xa khoom ntawm DC04?
A: Muab rau hauv txias-rolled annealed mob, nrog nto tiav ntawm FB (qib siab dua), FC (qib siab), thiab FD (super siab), feem ntau matte (D) los yog glossy (B).
Q: Dab tsi yog qhov tuab thiab dav dav rau DC04?
A: Thickness 0.18-0.80mm, dav 700-1230mm, puab txoj kab uas hla feem ntau 508mm los yog 420mm, ib yob hnyav ≤15.1 tons.
