KR (Korean Register) yog lub koom haum thoob ntiaj teb kev faib tawm lub luag haujlwm rau kev tshuaj xyuas thiab ntawv pov thawj ntawm cov nkoj thiab cov khoom siv hauv hiav txwv.
KR high-strength hull qauv steel yog muab faib ua qib zog raws li nws qhov tsawg kawg nkaus yield zog, thiab txhua qib zog yog muab faib ua A, D, E, thiab F 4 qib raws li nws cov kev cuam tshuam toughness.
A, D, E, thiab F feem sawv cev rau qhov cuam tshuam hnyav uas lawv tuaj yeem ua tiav ntawm 0 degree , -20 degree , -40 degree , thiab -60 degree feem.
