A36 Ship Building Steel Plate Naval Plate Marine Plate

according to the classification strength grade of the minimum yield strength, the strength grade and each according to its impact toughness of different level is divided into A, D, E, F4. A32, D32, E32, F32 the yield strength of not less than 315 n/mm ^ 2, the tensile strength of 440 ~ 570 n/mm ^ 2, A, D, E, F, respectively their respective respectively in 0 ° ~ 20 °, 40 °, 60 ° what can be achieved under the condition of impact toughness; A36, D36, E36, F36 the yield strength of not less than 355 n/mm ^ 2, the tensile strength of 490 ~ 620 n/mm ^ 2, A, D, E, F, respectively their respective respectively in 0 ° ~ 20 °, 40 °, 60 ° what can be achieved under the condition of impact toughness;
A40, old D40, E40, F40 the yield strength of not less than 390 n/mm ^ 2, the tensile strength of 510 ~ 660 n/mm ^ 2, A, D, E, F, respectively their respective respectively in 0 ° ~ 20 °, 40 °, 60 ° what can be achieved under the condition of impact toughness.
