Lub npe tag nrho ntawm EN 10297-1 tus qauv yog "Tshaj tawm cov xwm txheej rau seamless round steel hlab, Ntu 1: Cov hlau tsis muaj hlau thiab hlau hlau rau cov khoom siv kho tshuab thiab cov laj thawj dav dav". Txhawm rau kom ntseeg tau tias qhov loj me, zoo li, nto tiav thiab phab ntsa thickness ntawm lub raj ua tau raws li tus qauv yuav tsum tau ua.
EN 10297-1 cov raj tsis-alloy tshuab feem ntau suav nrog E235, E355, D470, C22E thiab C45E qib.
EN 10297-1 cov tshuab raj siv dav siv hauv kev siv tshuab thiab tshuab engineering, xws li cov khoom siv tsheb, cov qauv tsim, tshuab tshuab, thiab lwm yam.
