Dab tsi yog qhov txawv ntawmdc04 uathiab SPCC?
DC04 yog European tus qauv EN 10130, uas yog siab -qib txias- dov steel rau stamping. Nws muaj cov qib steel ntau dua thiab cov yas zoo dua, thiab tsim nyog rau kev sib sib zog nqus stamping.
SPCC yog tus qauv Japanese JIS G3141, uas yog cov qib txias txias -rolled steel nrog kev ua haujlwm yooj yim, haum rau kev stamping lossis cov khoom siv.
Dab tsi yog DC04 cov khoom siv qib?
DC04 yog qib plaub txias- dov qis carbon steel hauv European EN 10130 tus qauv. Nws yog cov khoom siv siab heev tsim los rau siab - stamping nyuaj. Nws yog "tus kws tshaj lij kos duab sib sib zog nqus" nyob rau hauv txias-cov hlau dov thiab yog qhov tsim nyog rau siab - nyuaj tsim dua DC01/SPCC.
Puas yog DC04 me me hlau?
Cov pa roj carbon tsawg yog hais txog carbon steel nrog cov ntsiab lus ntawm cov pa roj carbon tsawg dua 0.25%, thiab cov ntsiab lus ntawm DC04 feem ntau tsis tshaj 0.08%, yog li nws belongs rau cov hlau tsis muaj carbon steel thiab muaj cov yas zoo, weldability thiab txias ua haujlwm.
Puas yog CR3 zoo ib yam li DC04?
CR3 thiab DC04 yog ob qho tib si txias- dov qis- carbon hlau, tab sis lawv tsis zoo ib yam. CR3 yog ib qho dav dav -lub hom phiaj txias- dov steel raws li cov qauv hauv Suav teb, tsim nyog rau kev stamping zoo tib yam, thiab muaj tus nqi siab -effectiveness ratio; DC04 yog European qauv sib sib zog nqus nqus hlau nrog zoo ductility (Ntau dua lossis sib npaug rau 34%) thiab r-tus nqi (Ntau dua lossis sib npaug rau 1.8), thiab yog tsim los rau kev sib sau ua ke.
Dab tsi yog qhov txawv ntawm DC04 thiab CR3?
DC04 yog cov hlau tshwj xeeb rau kev sib sib zog nqus kos duab raws li European cov qauv, thaum CR3 yog lub hom phiaj dav dav dav hlau yob raws li Suav teb cov qauv.
