BV D460 thiab BV E460 yog ob qho tib si siab - lub zog shipbuilding steels pom zoo los ntawm Bureau Veritas nrog lub zog tsawg kawg nkaus ntawm 460 MPa. Qhov sib txawv tseem ceeb nyob rau hauv lawv qhov cuam tshuam qhov kub thiab txias: BV D460 yog kuaj ntawm -20℃C, thaum BV E460 raug kuaj ntawm qhov nruj dua -40℃C.
BV D460: Tsim los rau kev siv cov txheej txheem uas yuav tsum muaj qhov nruab nrab qhov tsis sib haum xeeb, haum rau qhov chaw ua haujlwm txias.
BV E460: Tsim los rau kev siv cov txheej txheem uas yuav tsum tau muaj kev sib tw siab, tsim nyog rau thaj chaw arctic lossis txias heev.
