Ob: Ntau yam Specifications
Cov qauv hlau rau lub plhaub tau muab faib ua cov qib zog raws li nws qhov tsawg kawg nkaus qhov taw qhia: dav dav-lub zog steel qauv thiab cov qauv hlau muaj zog.
Cov qauv steel qauv ntawm Tuam Tshoj Classification Society tus qauv muab faib ua plaub qib zoo: A, B, D, thiab E;Lub zog muaj zog steel qauv ntawm Tuam Tshoj Classification Society tus qauv yog peb qib zog thiab plaub qib zoo:

Cov Lus Qhia: Cov pa roj carbon sib npaug yog hais txog kev hloov cov nyhuv ntawm ntau yam alloying hauv cov hlau ntawm cov ntsiab lus ntawm cov ntsiab lus eutectic rau hauv qhov nce lossis txo cov pa roj carbon.

3. Kev taw qhia ntawm lub nkoj phaj 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 pub tsawg dua 235N / mm^2) thiab lub zog tensile (400 ~ 520N / mm^ 2) zoo ib yam, 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 raws li nws tej yam toughness., F4 qib.Lub zog tawm ntawm A32, D32, E32 thiab F32 tsis tsawg dua 315N / mm^2, thiab lub zog tensile yog 440 ~ 570N / mm^2.-40 °, -60 ° cuam tshuam toughness;yield zog ntawm A36, D36, E36, F36 tsis tsawg tshaj li 355N / mm^2, tensile lub zog yog 490 ~ 620N / mm^2, A, D, E thiab F sawv cev rau tej yam toughness uas yuav ua tau tiav ntawm 0 °, -20 °, -40 °, thiab -60 ° 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 toughness uas tuaj yeem ua tau. Ua tiav ntawm 0 °, -20 °, -40 °, thiab -60 ° feem.
