    一般強度船體結構用鋼分為A、B、D、E4個等級,這4個等級的鋼材的屈服強度(不小于235N/mm^2)和抗拉強度(400~520N/mm^2)一樣,只是不同溫度下的沖擊功不一樣而已;

    Normal strength hull structural steel is divided into A, B, D, E4 grades, the yield strength of the 4 grades of steel (less than 235N/mm^2) and tensile strength (400 ~ 520N/mm^2), just under the different temperature impact energy were different;

    高強度船體結構用鋼按其最小屈服強度劃分強度等級,每一強度等級又按其沖擊韌性的不同分為A、D、E、F4級。

    The strength of high strength hull steel is divided according to its minimum yield strength, and each strength grade is divided into A, D, E, F4 grade according to the different impact toughness.

    A32、D32、E32、F32的屈服強度不小于315N/mm^2,抗拉強度440~570N/mm^2,A、D、E、F分別表示其各自可分別在0°、-20°、-40°、-60°的情況下所能達到的沖擊韌性;

    The yield strength of A32, D32, E32 and F32 not less than 315N/mm^2, the tensile strength of 440 ~ 570N/mm^2, A, D, E and F respectively, their impact toughness can be respectively at 0 degrees, -20 degrees, -40 degrees, -60 degrees under the condition can be achieved;

    A36、D36、E36、F36的屈服強度不小于355N/mm^2,抗拉強度490~620N/mm^2,A、D、E、F分別表示其各自可分別在0°、-20°、-40°、-60°的情況下所能達到的沖擊韌性;

    The yield strength of A36, D36, E36 and F36 not less than 355N/mm^2, the tensile strength of 490 ~ 620N/mm^2, A, D, E and F respectively, their impact toughness can be respectively at 0 degrees, -20 degrees, -40 degrees, -60 degrees under the condition can be achieved;

    A40、D40、E40、F40的屈服強度不小于390N/mm^2,抗拉強度510~660N/mm^2,A、D、E、F分別表示其各自可分別在0°、-20°、-40°、-60°的情況下所能達到的沖擊韌性。

    The yield strength of A40, D40, E40 and F40 not less than 390N/mm^2, the tensile strength of 510 ~ 660N/mm^2, A, D, E and F respectively, their impact toughness can be respectively at 0 degrees, -20 degrees, -40 degrees, -60 degrees under the condition can be achieved.
