1.What yog tus qauv cov lus qhia ntawm DC04?
DC04 txias dov steel ua raws nrog EN 10130: 2006 thiab yog txias txias dov tsis- love carbon steel tau los ntawm batch analing los yog txuas ntxiv analing lossis txuas ntxiv analing lossis txuas ntxiv analing lossis txuas ntxiv analing lossis txuas ntxiv analing lossis txuas ntxiv analing lossis txuas ntxiv analing los yog nruam annealing.
2.What yog tshuaj lom neeg muaj pes tsawg leeg ntawm DC04?
Nws cov tshuaj lom neeg muaj pes tsawg carbon (c) tsawg dua lossis sib npaug rau 0.40%, thiab txhuas tsawg dua lossis sib npaug lossis ntau dua lossis sib npaug 0.015%. Cov ntsiab lus muaj roj carbon ntau muab cov hlau zoo nkauj no thiab weldability.
3.Qhov yog cov khoom siv tshuab ntawm DC04?
Cov txiaj ntsig lub zog yog 130-210mpa, lub zog tensile loj dua los yog sib npaug rau 270mpa, thiab lub elongation tom qab loj dua lossis sib npaug ntawm 34%. Lub siab tau elongation kom ntseeg tau tias cov khoom tuaj yeem yauv loj dua tsis muaj kev ntxhov siab thaum raug kev ntxhov siab, muab nws ua kom muaj peev xwm ua tau zoo heev.
4.Qhov dab tsi yog cov yam ntxwv ua kom zoo ntawm DC04?
Kev muaj peev xwm zoo: DC04 txias - ua cov khoom siv sib sib zog nqus thiab kos duab nrog kev tawg rog lossis tawg. Nws yog qhov haum rau kev tsim cov chaw tsim khoom yuav tsum tau ua kom sib sib nqus lossis muaj khoov.
Zoo heev nto zoo: dhau los ntawm kev txias - rolling stimes zoo li kev ua kom zoo, ua kom muaj zog} Cov khoom lag luam zoo nkauj, txhim kho cov khoom zoo thiab corrosion tsis kam.
Kev ua yeeb yam zoo nkauj: cov steel cov tshuaj muaj pes tsawg leeg thiab cov khoom siv neeg siv tshuab ua kom muaj kev hloov pauv tsawg, ua kom muaj kev ua tau zoo thaum ua haujlwm thiab siv.
5.Qhov twg yog thaj chaw thov ntawm DC04?
DC04 txias - rolled steel yog siv lub cev, xws li tso tsheb hlau luam, roj tso tsheb hlau luam, thiab lwm yam nyob hauv kev lag luam automotive; Lub tshuab nqus tsev, tshuab ntxhua khaub ncaws sab hauv, cua txias caserings, thiab lwm yam hauv kev lag luam hauv tsev; thiab rooj tog khoom ntiag rooj thiab cov khoom siv hauv chaw ua haujlwm hauv lwm daim teb.
