Txias Rolled DC04 Steel Chev
DC04 yog qhov siab - zoo sib sib zog nqus- kos qib txias- dov qis- cov pa roj carbon hlau tau txhais hauv European tus qauv EN 10130. Nws cov nqi tseem ceeb nyob hauv qhov sib sib zog nqus - kos duab kev ua tau zoo thiab nto zoo tshaj qhov txias txias- cov ntawv yob los ntawm qhov tseeb txias- txheej txheem dov thiab annealing kev kho mob, uas yog tshwj xeeb tshaj yog haum rau kev tsim cov khoom uas yuav tsum tau complex deformation ua.
Raws li qis- carbon steel, nws yog ib qho yooj yim rau rov siv dua thiab rov siv dua, uas yog nyob rau hauv txoj kab nrog kev txhim kho kev lag luam niaj hnub.
Advanced technology thiab nruj zoo tswj system xyuas kom meej tias cov khoom ua tau zoo heev ruaj khov thiab txhim khu kev qha nyob rau hauv lub coil thiab nruab nrab ntawm batch.
Kev tswj nruj nruj (thickness, dav, phaj zoo) ua kom du thiab ruaj khov thiab txo cov nqi ua tiav tom qab.
Tom qab precision dov thiab kev kho deg, txias dov coil DC04 muaj qhov ua tiav ntawm qhov chaw siab, tsis tshua muaj roughness thiab uniformity, thiab tuaj yeem siv ncaj qha rau cov khoom seem lossis ua cov txheej txheem siab - zoo.
Tshuaj muaj pes tsawg leeg (tus nqi raug raws li EN 10130)
Carbon (C): Tsawg dua lossis sib npaug rau 0.08%
Manganese (Mn): Tsawg dua lossis sib npaug rau 0.40%
Phosphorus (P): Tsawg dua lossis sib npaug rau 0.030%
Sulfur (S): Tsawg dua lossis sib npaug rau 0.030%
Cov ntsiab lus tsis tshua muaj alloying ua kom cov khoom txias txias zoo thiab weldability.
Cov khoom siv kho tshuab (tus nqi raug raws li EN 10130)
Yield zog (Rp0.2): 120 - 240 MPa (nyob ntawm thickness thiab mob)
Tensile zog (Rm): 270 - 350 MPa
Elongation ntawm tawg (A80mm): Ntau dua lossis sib npaug li 34% (feem ntau siab dua rau thickness Tsawg dua lossis sib npaug li 2 hli)
Plastic strain ratio (r-tus nqi): Ntau dua lossis sib npaug rau 1.8 (tus nqi nruab nrab, cuam tshuam tsis kam rau thinning)
Ua haujlwm hardening Performance index (n-tus nqi): Ntau dua lossis sib npaug rau 0.20 (xav txog kev muaj peev xwm deformation tsis sib xws)
