L-seem hlau sib npaug cov ces kaum - s35j2
S355j2 lub kaum sab xis steel
Cov Khoom Siv Npe: S355J2
Txheem: en 10025-2
Cov yam ntxwv: S355j2 yog lub siab-zog qis-alloy qauv hlau nrog zoo weldability, formability, thiab kev cuam tshuam ntawm tsawg kub. Nws yog qhov haum rau cov ntawv thov txheej txheem uas xav tau lub zog siab dua thiab tawv.
"J2" lub ntsiab lus: qhia tias cov hlau tau dhau qhov kev cuam tshuam nyuaj, ua tiav qhov tsawg kawg nkaus uas muaj 27 j / cm² ntawm {2} {2} degree.
