一般强度船体结构用钢分为A、B、D、E4个等级,这4个等级的钢材的屈服强度(不小于235N/mm^2)和抗拉强度(400~520N/mm^2)一样,只是不同温度下的冲击功不一样而已;

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;

高强度船体结构用钢按其最小屈服强度划分强度等级,每一强度等级又按其冲击韧性的不同分为A、D、E、F4级。

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的屈服强度不小于315N/mm^2,抗拉强度440~570N/mm^2,A、D、E、F分别表示其各自可分别在0°、-20°、-40°、-60°的情况下所能达到的冲击韧性;

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的屈服强度不小于355N/mm^2,抗拉强度490~620N/mm^2,A、D、E、F分别表示其各自可分别在0°、-20°、-40°、-60°的情况下所能达到的冲击韧性;

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的屈服强度不小于390N/mm^2,抗拉强度510~660N/mm^2,A、D、E、F分别表示其各自可分别在0°、-20°、-40°、-60°的情况下所能达到的冲击韧性。

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.
