European Txias-Rolled Steel daim hlau, dav siv rau kev sib sib zog nqus teeb meem thiab kev sau ua cov ntawv thov, tau faib rau hauv ntau cov khoom siv sib txawv cov khoom siv tshwj xeeb. Cov qhab nia no txhais nyob rau hauv EN 10130 koob meej thiab feem ntau sib txawv ntawm cov txiaj ntsig zoo, thiab elongation muaj zog, yog li muaj kev cuam tshuam lawv cov kev ua kom tau zoo thiab kev ua tau zoo.
Dc01yog qib siab tshaj plaws nyob rau hauv koob, muab kev ua kom muaj txiaj ntsig zoo tshaj plaws thiab ductility. Nws cov txiaj ntsig tsawg los ua rau nws zoo tagnrho rau cov ntawv thov uas yuav tsum tau sib sau, xws li cov khoom siv tsheb kho tsheb thiab cov khoom siv hauv tsev. Vim tias nws cov kev kos zoo, DC01 yog feem ntau xaiv thawj qhov uas yauv tsis muaj deformation tseem ceeb thaum tsim khoom.
Dc03sawv cev rau ib kauj ruam nyob rau hauv lub zog piv rau DC01, nrog kev nce qib me ntsis hauv kev tawm lub zog. Cov qib no tawm tsam qhov sib npaug ntawm kev ua kom muaj formability thiab kev ua haujlwm zoo, ua kom haum rau cov khoom siv uas xav tau ob qho tib si du thiab txhim kho lub zog. Nws yog feem ntau siv nyob rau hauv cov chaw uas xav tau kev sib sau ua kom muaj kev ntseeg siab.
Dc04txuas ntxiv nce ntxiv cov paib muaj zog thaum tswj cov theem uas pom tau zoo ntawm kev muaj peev xwm. Nws yog feem ntau xaiv rau cov ntawv thov uas xav tau cov khoom muaj peev xwm siab dua thaum tseem tab tom ua cov txheej txheem. Lub zog txhim kho ntawm DC04 ua rau nws nrov hauv cov chaw uas ruaj khov yog qhov tseem ceeb tshaj plaws.
Dc05thiabDc06yog cov qib siab-zog hauv cov koob no. DC05 muaj ntau dua txhim kho tensile muaj piv rau cov qib qis, ua rau nws haum rau cov khoom uas yuav tsum tau tiv thaiv ntau dua. DC06, nrog lub zog siab tshaj plaws lub zog thiab tensile lub zog ntawm DC cov qhab nia tau ua tau zoo tab sis qhov twg yuav tsum tau tsim nyog ntawm cov kev cai. Cov qhab nia no feem ntau yog siv rau hauv cov ntawv siv muaj kev lag luam thiab cov qauv txheej txheem.
Saib xyuas cov qhab nia hauv European mus rau Suav cov qauv hauv tebchaws tuaj yeem nyuaj vim muaj kev sib txawv vim kev sib txawv hauv cov ntawv qhia; Txawm li cas los xij, cov cuab yeej kho tshuab muab rau kev sib txig sib luag. Suav teb cov qauv, xws li cov uas tau hais hauv GB / T 699-2015 Cov ntawv tsis zoo rau cov khoom siv txias, rau lub zog txias, lub zog tensile, thiab elongation. Piv txwv li, qhov kev muaj txiaj ntsig zoo ntawm European DC01 sib raug rau Suav Stand grades tsim rau kev sib sib zog nqus duab nrog qis zog zog. Ib yam li ntawd, cov yam ntxwv nruab nrab thiab cov yam ntxwv siab ntawm DC03 rau DC06 tuaj yeem sib phim nrog cov qib hauv Suav uas muaj kev ua tau zoo sib npaug ntawm lub zog thiab ductility. Cov kws ua choj feem ntau piv cov ntaub ntawv ntxaws ntxaws xws li cov txiaj ntsig thiab cov qhab nia hauv Suav tau ua tiav cov ntaub ntawv uas xav tau raws li cov ntaub ntawv European.
