Lub zog dav dav hlau rau cov qauv hull tau muab faib ua plaub qib: A, B, D thiab E.
Lub zog tawm los (tsis tsawg dua 235N / mm^2) ntawm plaub qib ntawm cov hlau no yog tib yam li lub zog tensile (400-520N / mm^2), tab sis qhov cuam tshuam lub zog ntawm qhov kub thiab txias sib txawv.
High-strength hull structural 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, F4 qib raws li nws tej yam toughness.
Lub zog tawm ntawm A32, D32, E32, thiab F32 tsis tsawg dua 315N / mm^2, thiab lub zog tensile yog 440-570N / mm^2. Impact toughness ntawm -40 degree , -60 degree ;
Lub zog tawm ntawm A36, D36, E36, F36 tsis tsawg dua 355N / mm^2, tensile lub zog yog 490-620N / mm^2. A, D, E thiab F sawv cev rau qhov cuam tshuam qhov hnyav uas tuaj yeem ua tiav ntawm 0 degree , -20 degree , -40 degree , thiab -60 degree feem;
Lub zog tawm ntawm A40, D40, E40, thiab F40 tsis tsawg dua 390N/mm^ 2. Lub zog tensile yog 510-660N/mm^2, thiab A, D, E, thiab F sawv cev rau qhov cuam tshuam qhov hnyav uas tuaj yeem ua tiav ntawm 0 degree , -20 degree , -40 degree , thiab -60 degree feem.
