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.
KR A70 D70 E70 F70 nkoj phaj flaw nrhiav kom tau:
thawj nrhiav tau, thib ob nrhiav tau, thib peb nrhiav tau.
KR A70 D70 E70 F70 shipbuilding steel phaj ceev:
7.85/m3.
KR A70 D70 E70 F70 nkoj phaj hnyav hloov mis:
thickness * dav * ntev * ntom.
KR A70 D70 E70 F70 marine qib steel phaj li niaj zaus:
8-80mm*2000-2500mm*{2}} hli
GNEE STEEL muaj peev xwm los txiav txim rau tag nrho cov nkoj ntawm txhua lub zog, txhua qhov tshwj xeeb, thiab txhua hom nkoj pej xeem. Nws tuaj yeem muab cov phaj hlau rau txog li 400,000-tuj roj tankers thiab 24,000 TEU thawv nkoj, ua tiav 'ib-nres kev daws teeb meem' rau cov neeg siv khoom xav tau.
