A36 Gr.B Marine steel plate

General strength hull structure steel is divided into A, B, D, E4 grades, these 4 grades of steel yield strength (not less than 235N/mm^2) and

tensile strength (400 ~ 520N/mm^2) the same, but the impact force at different temperatures is not the same;

High-strength steel for hull structure is divided into strength grades according to its minimum yield strength, and each strength grade is divided

into A, D, E and F4 grades according to its impact toughness.  The yield strength of A32, D32, E32 and F32 is not less than 315N/mm^2, and the

tensile strength is 440 ~ 570N/mm^2.  A, D, E and F respectively indicate that they can be separated respectivelImpact toughness that can be 

achieved at 0°, -20°, -40°, -60°;  The yield strength of A36, D36, E36 and F36 is not less than 355N/mm^2, and the

tensile strength is 490 ~ 620N/mm^2.  A, D, E and F respectively indicate that they can be used at 0°, 0°, 0°.

Impact toughness achieved at -20°, -40°, -60°;  The yield strength of A40, D40, E40 and F40 is not less than 390N/mm^2, the tensile strength of

510 ~ 660N/mm^2, A, D, E and F respectively indicate the impact toughness that can be achieved at 0°, -20°, -40° and -60° respectively.

【 Expression method of ship plate steel plate 】

The complete representation is as follows:

General strength structural steel and high strength structural steel.  Ship plate refers to the hot-rolled steel plate produced according to the

requirements of the classification society construction code for the manufacture of ship structure.  The general strength structural steel of China

Classification Society is divided into: A, B, D, E four quality grades (CCSA, CCSB, CCSC, CCSD);  The high strength structural steel according to the

China Classification Society specification has three strength levels and four quality levels.
