DC01 txhais li cas?
DC01" tuaj yeem muaj lub ntsiab lus sib txawv nyob ntawm cov ntsiab lus. Ntawm no yog qee qhov kev txhais lus:
Hauv cov khoom siv hlau: DC01 yog hom txias - dov steel ntawv. Nws belongs rau cov dav dav - lub hom phiaj txias - dov steel series thiab yog dav siv nyob rau hauv kev tsim ntawm ntau yam khoom xws li tsheb, khoom siv hauv tsev, thiab hlau khoom vim nws zoo formability thiab nto zoo.
DC01 steel sib npaug li cas?
DC01 steel yog European - tus qauv txias - dov qis - carbon steel ca khoom rau txias forming6. Nws cov hlau sib npaug hauv lwm cov qauv yog raws li hauv qab no5:
Suav tus qauv: Nws yog sib npaug rau 08, 08F, thiab 08Al hauv GB / T 5213 - 2019. Tus lej steel hauv Baosteel tus qauv yog DC01, thiab cov qauv sib xws yog Q / BQB 403.
DC 01 khoom yog dab tsi?
DC01 yog txias - dov qis - carbon steel phaj los yog sawb khoom1. Nov yog cov lus qhia ntxaws:
Chemical composition1: Cov ntsiab lus tseem ceeb muaj xws li carbon (C), manganese (Mn), phosphorus (P), sulfur (S), thiab lwm yam. Cov feem ntau ntawm cov pa roj carbon tsawg dua los yog sib npaug li 0.12%, manganese Tsawg dua lossis sib npaug li 0.60%, sulfur Tsawg dua lossis sib npaug li 0.045%, phosphorus 0.0 thiab cov ntsiab lus sib npaug ntawm 0.045%, phosphorus tsawg dua 0. yog Ntau dua lossis sib npaug rau 0.020%.
Mechanical properties1: Lub zog tensile (σb) yog 270 - 410MPa, lub zog tawm los (σs) yog 130 - 260MPa, thiab qhov elongation tom qab tawg (δ5) yog ntau dua lossis sib npaug li 28%.
Qhov txawv ntawm DC01 thiab DC03 yog dab tsi?
1. Tshuaj muaj pes tsawg leeg
Cov ntsiab lus carbon:
DC01: Feem ntau muaj cov ntsiab lus siab dua piv rau DC03. Cov ntsiab lus carbon hauv DC01 feem ntau yog tsawg dua lossis sib npaug li 0.12%.
DC03: Nws muaj cov ntsiab lus qis dua. Qhov qis carbon qib no muaj txiaj ntsig zoo rau kev txhim kho qee yam khoom, tshwj xeeb tshaj yog formability.
Lwm cov ntsiab lus: Tag nrho cov tshuaj pleev ib ce ntawm ob lub steels kuj muaj xws li manganese, phosphorus, thiab sulfur, tab sis cov proportions meej yuav txawv me ntsis kom ua tiav cov yam ntxwv sib txawv.
Qhov txawv ntawm DC01 thiab DC05 yog dab tsi?
DC01 tuaj yeem siv rau kev ua haujlwm yooj yim, piv txwv li Bending, embossing, hlaws thiab rub. DC03 yog qhov tsim nyog rau kev tsim cov kev xav tau zoo li kev kos duab sib sib zog nqus thiab nyuaj profiles haum. DC04 yog tsim rau siab deformation yuav tsum. DC05 yog qib thermal forming, nws tsim nyog rau kev tsim ntau dua.
