Grade A marine steel

Classification of marine steel

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 according to its impact toughness.

1、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 represent the impact toughness that can be achieved at 0°, -20°, -40° and -60° respectively.
2、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 represent the impact toughness that can be achieved at 0°, -20°, -40° and -60° respectively.
3、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.

Grade A and Q235B

In general, the ABS Grade A ship building plates and Q235B mild steel plates almost have no big difference in chemical composition and mechanical properties. That is why a lot of clients can also accept to use Q235B carbon steel. Under such condition, the Q235B has advantages as: fast delivery and lower price also.
