S3555j2wp huab cua dav hlauhas good low-temperature toughness and generally does not become brittle easily in conventional low-temperature environments, Ua tsaug rau nws cov ntaub ntawv muaj pes tsawg leeg thiab cov qauv J2 "ntawm qib kawm hauv nws lub npe. Hauv qab no yog qhov tseeb tawg:
Lub "J2" hauv S35555555555555555555555555555sp yog txhais los ntawm European txheemEN 10025-5(rau huab cua cov hlau). Nws qhia meej meej yuav tsum tau cov hlau kom tau raws li qhov cuam tshuam tsawg kawg nkaus ntawm27 J (Joules)ntawm qhov kub ntawm-20℃(-4℃f).
Qhov no txhais tau tias S355j2WP yog cov qauv tshwj xeeb (piv txwv li cov ntsiab lus carbon monoxide,
Brittleness tsis yog qhov teeb meem xam rau S355j2Wp, tab sis ob qho xwm txheej yuav ua rau nws qhov qis qis- kub ua tau:
Txom nyem vuam / ua kom zoo: Yog tias vuam yog ua tiav nrog cov kev ua haujlwm tsis sib xws lossis tsis muaj qhov ua kom tuab), txhaws cov microstructures uas tsis cuam tshuam rau qhov kub tsawg.
Huab Ultra -} Tsawg Kub: Tshaj dhau nws cov ntsuas-20 degree, xws li -40℃lossis qis dua (txawm tias thaj chaw sab nrauv), txawm tias qhov no tseem nyob deb ntawm cov ntawv thov siv tau ntau).
Rau yuav luag txhua qhov tsawg {{0 eg, lub caij ntuj no nyob hauv Tebchaws Europe, lossis kub sab qaum tebyuav tsis ua brittleCov. Nws yog dav siv nyob rau hauv qhov qis qis qis - qhov kev thov kub thiab siv cov qauv hluav taws xob, thiab cov txheej txheem sab nraum zoov yam tsis muaj plitture kev txhawj xeeb.
